# Account
Source: https://docs.machine0.io/cli/account
CLI reference for authentication, billing, and configuration.
## login
Log in via browser OAuth. Session token stored at `~/.machine0/auth-token`.
```bash theme={"theme":"css-variables"}
machine0 login
```
***
## logout
Log out and revoke the session token.
```bash theme={"theme":"css-variables"}
machine0 logout
```
`MACHINE0_API_TOKEN` env var is unaffected by logout. Unset it separately.
***
## account
Show account details and wallet balance.
```bash theme={"theme":"css-variables"}
machine0 account
```
***
## topup
Add funds via Stripe. Minimum \$5.
```bash theme={"theme":"css-variables"}
machine0 topup --amount 10
```
***
## config get
```bash theme={"theme":"css-variables"}
machine0 config get
```
Each value is labeled with its source: `(env)` = environment variable, `**` = project `machine0.env`, `*` = home config (`~/.machine0/machine0.env`). Unmarked values are built-in defaults.
***
## config set
```bash theme={"theme":"css-variables"}
machine0 config set KEY=VALUE [KEY=VALUE ...]
```
Writes to `~/.machine0/machine0.env`. Warns per key when the saved value is currently shadowed by an environment variable or a project `machine0.env`.
See [Configuration](/platform/configuration) for all settings.

## use openclaw
Create an OpenClaw VM and SSH in. Auto-generates a name with `openclaw-` prefix.
```bash theme={"theme":"css-variables"}
machine0 use openclaw
```
# Disks
Source: https://docs.machine0.io/cli/disks
CLI reference for creating, inspecting, listing, and removing persistent disks.
Disks are persistent block storage volumes tied to a region. A disk can
be attached to one VM at a time — either at VM creation (`new --attach`) or
onto an already-running VM (`disks attach`) — and its data survives
suspend/resume and VM destruction — the disk keeps living (and billing) until
you remove it. Disks are billed per GB-hour while they are `READY`
(\~\$0.1667/GB/month).
Disks are durable but **not backed up** — removing a disk (or deleting files
on it) is permanent.
Once mounted, the disk is owned by the VM's normal login user (not `root`),
so it's writable without `sudo` out of the box.
## disks new
Create a disk. The command returns immediately with the disk in a `CREATING`
state; it becomes `READY` on its own, usually within seconds (check with
`disks ls`).
```bash theme={"theme":"css-variables"}
machine0 disks new --size [--region ]
```
| Flag | Description | Default |
| ----------------------- | -------------------------- | ------------------- |
| `-s, --size ` | Disk size in GB (10–16384) | required |
| `-r, --region ` | Region the disk lives in | your default region |
```bash theme={"theme":"css-variables"}
$ machine0 disks new data --size 50 --region eu
✓ Disk "data" is being created (50 GB, eu)
Check status: machine0 disks ls
Once READY, attach it to a new VM: machine0 new --attach disk:data path:/data
```
Disk names use lowercase letters, numbers, and hyphens (max 31 characters).
Each account can have up to 10 disks. A disk can only be attached to VMs in
its own region.
***
## disks ls
List your disks.
```bash theme={"theme":"css-variables"}
machine0 disks ls
```
| Flag | Description | Default |
| -------- | ----------- | ------- |
| `--json` | Output JSON | off |
```bash theme={"theme":"css-variables"}
$ machine0 disks ls
┌──────────────────────────────────────────────────┐
│ Name Status Size Region Attached To │
│ data READY 50 GB eu dev1 │
└──────────────────────────────────────────────────┘
```
`Attached To` names the VM the disk is currently attached to, with
`(attaching...)` or `(detaching...)` while an `attach`/`detach` is still in
flight. A disk in `ERRORED` state failed to provision — run `disks get `
for the error, then `disks rm ` to clean it up and create it again.
***
## disks get
Show a disk's details — status, size, region, cost, and which VM it's
attached to.
```bash theme={"theme":"css-variables"}
machine0 disks get
```
| Flag | Description | Default |
| -------- | ----------- | ------- |
| `--json` | Output JSON | off |
```bash theme={"theme":"css-variables"}
$ machine0 disks get data
DISKS > data
Name data
Status READY
Attached To dev1:/data
Size 50 GB
Region eu
$/month $8.43
Total Cost $6.05
Created At 07/11/2026 @ 18:10 (21d 20h 3m ago)
```
For `ERRORED` disks the provider error is shown (for example, a volume quota
being exhausted) so you know whether recreating will help.
***
## disks rm
Remove a disk and **all of its data**, permanently. Refused while any VM
(including a suspended one) is still attached to the disk — destroy the VM
first.
```bash theme={"theme":"css-variables"}
machine0 disks rm
```
| Flag | Description | Default |
| ----------- | ---------------------------- | ------- |
| `-y, --yes` | Skip the confirmation prompt | off |
```bash theme={"theme":"css-variables"}
$ machine0 disks rm data -y
✓ Disk "data" destroyed
```
The command returns immediately — the disk disappears from `disks ls` at once
and its name is instantly reusable, while the volume is deleted in the
background. `disks rm` also works on `CREATING` disks (cancels provisioning)
and `ERRORED` disks (cleanup).
***
## disks attach
Attach a `READY` disk to an already-running VM.
```bash theme={"theme":"css-variables"}
machine0 disks attach --path
```
| Flag | Description | Default |
| ------------------- | ----------------------------------- | -------- |
| `-p, --path ` | Absolute path to attach the disk at | required |
```bash theme={"theme":"css-variables"}
$ machine0 disks attach data dev1 --path /data
✓ Disk "data" is being attached to "dev1" at /data
Check status: machine0 disks get data
```
The command returns immediately with the attachment in an `attaching...`
state; `disks get`/`disks ls` show `ATTACHED` once the disk is actually
mounted inside the VM. The disk must be `READY`, in the same region as the
VM, and not attached to another VM; the VM must be `RUNNING` and have a
managed SSH key (the same requirement as `machine0 ssh`) — a VM created with
your own public key can't be attached to post-hoc. Up to 5 disks can be
attached per VM, and mount paths can't be nested inside one another. Not yet
supported on GPU sizes or NixOS VMs.
Disks attached with `disks attach` persist across reboots and suspend/resume,
same as disks attached at VM creation.
***
## disks detach
Detach a disk from the VM it's attached to.
```bash theme={"theme":"css-variables"}
machine0 disks detach
```
```bash theme={"theme":"css-variables"}
$ machine0 disks detach data
✓ Disk "data" is being detached
Check status: machine0 disks get data
```
The command returns immediately with the attachment in a `detaching...`
state; the disk disappears from the VM (unmounted and disconnected) once the
job finishes. If the VM has an open file handle on the mount path, the detach
retries rather than forcing it; if it still can't unmount after a few
minutes, the attachment returns to `attached` — stop whatever is using the
mount path and run `disks detach` again.
Like `disks attach`, detaching needs the VM `RUNNING` with a managed SSH key
(the same requirement as `machine0 ssh`) — the command fails immediately with
the reason otherwise. A disk attached to a VM created with your own public
key can't be detached at all (the server can't SSH in to unmount safely);
destroying the VM releases the disk.
A disk still `attaching...` can't be detached yet — wait for the attach to
finish (or fail) first, then retry.
***
## Attaching disks: `new --attach`
Attach disks when creating a VM with the repeatable `--attach` flag on
[`machine0 new`](/cli/machines#new). Each use takes two values: the disk and
the absolute path to attach it at.
```bash theme={"theme":"css-variables"}
machine0 new --attach disk: path:
```
```bash theme={"theme":"css-variables"}
# one disk
machine0 new dev1 --attach disk:data path:/data
# several disks
machine0 new dev1 \
--attach disk:data path:/data \
--attach disk:code path:/code
```
Mount paths must be absolute (letters, numbers, `/`, `_`, `-`), cannot be
inside system directories (`/etc`, `/usr`, `/var`, ...), and cannot be nested
inside one another (e.g. `/data` and `/data/code`) — this applies across all
disks attached to the VM. The disk must be
`READY`, in the same region as the VM, and not attached to another VM. Up to
5 disks can be attached per VM. Attachments survive reboots and suspend/resume
— on resume the disk is re-attached with its data intact. Disks are not yet
supported on GPU sizes or NixOS VMs.
Creation-time attachments work on any eligible VM (they don't need SSH), including
one created with your own public key (`-k`) — but note that such a disk
can't be detached later ([`disks detach`](#disks-detach) needs server SSH
access); destroying the VM is what releases it.
To attach a disk to a VM that's already running (instead of at creation
time), use [`disks attach`](#disks-attach) / [`disks detach`](#disks-detach).
# Profile variables
Source: https://docs.machine0.io/cli/env
CLI reference for env — env variables stored on a profile and injected into every VM created with it, with optional write-only secrets.
The `env` commands manage the env variables stored on a [profile](/cli/profiles). They are stored encrypted and injected into every VM created with `machine0 new --profile ` — written to `/etc/environment` (services and non-login shells) and `/etc/profile.d/machine0-env.sh` (interactive sessions).
Commands target the [current profile](/cli/profiles#profiles-use); pass `-p/--profile` to target another one. The whole group is also available as `machine0 vars` (its pre-1.0.146 name), kept for backward compatibility.
***
## env ls
List a profile's variables. Secret values render masked.
```bash theme={"theme":"css-variables"}
machine0 env ls
machine0 env ls -p work --json
```
***
## env set
Set env variables in a profile (`KEY=VALUE`, space-separated, values may contain `=`). Aliased as `env add`.
```bash theme={"theme":"css-variables"}
machine0 env set KEY=VALUE [KEY=VALUE ...] [--secret] [-p ]
machine0 env set NODE_ENV=production API_URL=https://api.example.com
machine0 env set OPENAI_API_KEY=sk-... --secret -p work
```
**Secret variables** — pass `--secret` to mark every key in that invocation as secret. Secret **values** are write-only: `env ls` and `profiles get` (including `--json`) show them as `******** (secret)` and no API read ever returns them again — they stay readable only inside a VM (e.g. in `/etc/environment`). Key names and their existence remain visible, as for any variable. Details:
* Re-setting a key **without** `--secret` un-marks it (the new value displays in cleartext); re-setting with `--secret` keeps it masked.
* Masked `env ls --json` output is **not round-trippable**: piping it back into `env set` is rejected (it would overwrite the real value with the placeholder). The literal `********` can never be stored as a variable value.
* Variables set before this feature existed aren't retroactively masked — re-set them with `--secret` to mark them.
A variable named `ANTHROPIC_API_KEY` or `OPENAI_API_KEY` competes with a connected [`claude-code` or `codex` integration](/cli/integrations#integrations-connect) on the same profile: the VM ends up holding both credentials, and which one the agent uses depends on the provider's own precedence rules. Pick one mechanism per provider.
`MACHINE0_API_KEY` and `MACHINE0_MCP_URL` are [auto-populated on profiled VMs](/platform/profiles#environment-variables) with the profile's MCP gateway endpoint and a matching API key. Setting **either** name yourself disables injection of **both** (the two only make sense as a pair), and your values are used instead.
**When changes apply** — variables are written when a VM boots (at creation and on resume from suspend) and whenever the profile is re-applied to a running VM with [`profiles deploy`](/cli/profiles#profiles-deploy). Outside those events, a running VM does not pick up `env set`/`unset` changes.
Profiles hold up to 100 variables (64KB serialized); keys are `[A-Za-z_][A-Za-z0-9_]*`, values up to 4096 characters of printable ASCII: no newlines, tabs, double quotes, or non-ASCII characters such as em dashes and emoji (non-ASCII breaks VM provisioning).
***
## env unset
Remove env variables from a profile by key. Aliased as `env rm`. A key that isn't set in the target profile is an error and nothing is removed — this catches typos (and a profile name passed as a key) before a deletion lands on the wrong target. Removal asks for confirmation naming the profile — secret values are write-only, so a removed secret can't be recovered; pass `--yes` to skip the prompt (required in scripts).
```bash theme={"theme":"css-variables"}
machine0 env unset KEY [KEY ...] [-p ]
machine0 env unset API_URL
machine0 env rm API_URL -p work --yes # skip the confirmation prompt
```

## images get
```bash theme={"theme":"css-variables"}

***
## images new
Snapshot a VM into a reusable image. The VM is stopped automatically before snapshotting.
```bash theme={"theme":"css-variables"}

| `-d, --description` | Image description |
| `-m, --metadata` | JSON metadata for the version |
### Building from a git repo
With `--git-repo`, `images new` builds a NixOS image server-side from a public GitHub repo's nix flake instead of snapshotting a VM. The branch is resolved to its latest commit at submit time and the commit is recorded on the image version.
```bash theme={"theme":"css-variables"}
machine0 images new --git-repo https://github.com// --nix-profile [flags]
```
| Flag | Description |
| ------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `--git-repo` | Public GitHub repository URL (`https://github.com//`) |
| `--git-branch` | Branch to build (default: `main`) |
| `--nix-profile` | Flake profile to apply — a `nixosConfigurations` attribute, e.g. `base` or `loaded` |
| `--size` | Builder VM size (default: `large`). The builder's disk size becomes the image's minimum VM size — bigger builders build faster but produce images that only boot on equally big VMs |
| `--region` | Builder VM region |
| `--no-wait` | Return immediately instead of waiting for the build |
| `-d, --description` | Image description |
| `-m, --metadata` | JSON metadata for the version |
How it works: a temporary builder VM named `m0-build-*` boots from the NixOS base image, applies `nixos-rebuild switch --flake github://#`, is snapshotted, and destroyed. The builder is visible in `machine0 ls` and bills like a normal machine for the duration of the build (typically 10–40 minutes). A brand-new image name is published immediately on success; building onto an existing image creates a draft version to test and promote, same as a snapshot save.
If the build fails, the error (including the tail of the `nixos-rebuild` log) is recorded on the image version — see it with `machine0 images versions get ` — and re-running the same command retries against the branch's latest commit.
Limitations (v1): public GitHub.com repositories only; no git submodules or LFS (the flake is fetched as a tarball); the profile must import the machine0-nixos base modules (keep the `nix` user and SSH enabled), or the build fails verification.
***
## images update
```bash theme={"theme":"css-variables"}
machine0 images update [flags]
```
| Flag | Description |
| ------------------- | ------------------------------------------------------------------------------------ |
| `-n, --name` | New name |
| `-d, --description` | New description |
| `-r, --region` | Comma-separated regions to add (additive — regions can't be removed from a snapshot) |
***
## images rm
```bash theme={"theme":"css-variables"}
machine0 images rm [image] [flags]
```
| Flag | Description |
| ----------- | ----------------- |
| `-a, --all` | Delete all images |
| `-y, --yes` | Skip confirmation |
Deleting the auto-saved snapshot of a [suspended](/platform/vm-management) machine (named `suspended---`) also destroys that machine -- the snapshot is its only copy of its disk. Check `machine0 ls` for suspended machines before removing `suspended-*` images.
# Integrations
Source: https://docs.machine0.io/cli/integrations
CLI reference for integrations — connect Claude Code, Codex, GitHub, and remote MCP servers to a profile, with per-profile credentials.
Integrations belong to a [profile](/cli/profiles) and connect your machine0 account to external services, storing the resulting credentials encrypted. Commands target the [current profile](/cli/profiles#profiles-use); pass `-p/--profile` to target another one. Four integrations are available in every profile — `claude-code` (Anthropic API key or Claude Code OAuth credentials), `codex` (OpenAI API key or Codex OAuth credentials — VMs created with the profile get a logged-in `codex` plus the profile's MCP endpoint preconfigured), `github` (a GitHub App installation for `gh` and `git push`/`clone` — you pick exactly which repositories during connect), and `machine0-cli` (a machine0 API key so the machine0 CLI works inside a VM) — and you can add any remote HTTP MCP server as a custom integration (for example Linear's official server at `https://mcp.linear.app/mcp`). Each is connected per profile.
Credentials are stored encrypted at rest. OAuth connections open your browser for the provider's consent screen; `claude-code` also asks you to paste the Claude callback URL or `code#state` back into the CLI, which exchanges the code with Anthropic locally before uploading the encrypted credential payload to machine0. `codex` works the same way but captures the browser callback automatically on `localhost:1455` (the same loopback `codex login` uses) — if the callback can't reach your terminal (running the CLI over SSH, or the port is busy), paste the full callback URL from the browser's address bar instead; the OpenAI token exchange also runs locally. `machine0-cli` connects instantly (it mints an API key server-side, visible in your account's token list as `machine0-cli-integration`).
Disconnecting an integration deletes machine0's stored credentials, but does **not** remove credentials already injected into running VMs, suspend snapshots, or custom images baked from them. For `codex` in particular, `~/.codex/auth.json` on a VM keeps working (it self-refreshes) until you log out of codex on the VM or destroy it — and an image created from a codex-authenticated VM carries that file. API keys are yours, not machine0's: disconnecting deletes machine0's copy but the key itself stays valid at the provider (and inside already-provisioned VMs) until you revoke it in the Anthropic or OpenAI console.
***
## integrations ls
List a profile's integrations with their connection status — system integrations first, then custom MCP integrations, each group alphabetical.
```bash theme={"theme":"css-variables"}
machine0 integrations ls
machine0 int ls -p work --json
```
An integration is only ever **connected** or **disconnected**:
| Status | Meaning |
| ---------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------- |
| `connected` (green) | credentials are stored and the last `integrations check` passed |
| `disconnected` (red) | credentials are stored but the last `integrations check` failed (e.g. a revoked token) — reconnect, or re-run `check` after fixing the cause |
| `disconnected` (plain) | not connected in this profile — either run `integrations connect`, or (for `github`) the provider's GitHub App isn't configured on this server |
Plain `disconnected` covers two cases; the reason differs, so read the row's message rather than assuming it always means "run connect". The detail view (`integrations get `) shows `configured: no` when the server has no OAuth credentials for the provider.
Each integration's credentials record when they were last verified — shown in the **Last checked** column of the profile-wide [`integrations check`](#integrations-check) output and carried as a full timestamp in `--json`. The stamp is set when the integration connects and refreshed by every `integrations check`; for MCP integrations that authenticate with OAuth, the server also verifies (and silently refreshes) the stored tokens on a periodic background sweep, so it can advance without you running anything — and a token the provider has revoked or expired is detected and cleared in the background too, flipping the integration to `disconnected` before you next use it. `--` means never checked — for custom MCP servers that need no authentication this is permanent, since there are no stored credentials to record a check against (the server is still probed and its tools still served).
***
## integrations get
Show one integration's details — its status, which external account is connected (an API-key connection shows a masked key label instead, e.g. `API key (sk-ant-...abcd)`), description, and the last check's outcome. For MCP integrations the CLI also probes the server live and lists the **prompts and tools** it exposes through the profile's MCP endpoint (with any [prefix and tool whitelist](#integrations-update) applied), and the attributes include the configured `prefix` (`--` when unset) and `tool whitelist`. The live probe updates the integration's stored health exactly like [`integrations check`](#integrations-check) does — including the silent OAuth token refresh, and removal of dead credentials when the refresh is rejected upstream. Built-in integrations keep the fast attribute-only view.
```bash theme={"theme":"css-variables"}
machine0 integrations get [-p ]
machine0 integrations get github --json
machine0 integrations get notion -p work # live PROMPTS + TOOLS for MCP servers
```
***
## integrations new
Add a remote HTTP MCP server to a profile as a custom integration. Aliased as `integrations create` and `integrations add`.
Integration names follow the same rules as machine names (letters, digits, and dashes; max 63 characters), and built-in names and close aliases (`claude-code`, `claude`, `anthropic`, `codex`, `openai`, `chatgpt`, `github`, `machine0-cli`, and `machine0`) are reserved. Each profile holds up to 50 integrations, and the same name can exist in different profiles. Only HTTP(S) MCP servers are supported, and URLs must be public — private, loopback, and link-local addresses are rejected.
Integrations added with `integrations new` get a default tool/prompt prefix of `_` — an integration named `deepwiki` exposes its tools as `deepwiki_` through the profile MCP endpoint, so each integration's tools are namespaced. Change or remove it with [`integrations update --prefix`](#integrations-update). Integrations added before this default existed are unchanged: any prefix you set still applies, and unprefixed ones serve the server's original names until you set a prefix. [`profiles duplicate`](/cli/profiles#profiles-duplicate) copies each integration's prefix as-is.
```bash theme={"theme":"css-variables"}
machine0 integrations new --url [-p ]
machine0 integrations new deepwiki --url https://mcp.deepwiki.com/mcp
```
***
## integrations update
Update a custom MCP integration's settings. Built-in integrations can't be updated. Pass `""` to any flag to clear it.
```bash theme={"theme":"css-variables"}
machine0 integrations update [flags] [-p ]
machine0 int update notion -d "Team Notion workspace"
machine0 int update notion --prefix notion_
machine0 int update notion --tool-whitelist list,get
machine0 int update notion --prefix "" --tool-whitelist "" # clear both
```
| Flag | Effect |
| ---------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `-d, --description ` | description shown in `integrations ls`/`get` and `profiles get` |
| `--prefix ` | renames **every tool and prompt** the server exposes through the profile MCP endpoint to `` (e.g. `notion_search`). New integrations start with `_`; pass `""` to remove prefixing entirely. Letters, digits, `_`, `-`; max 64 characters |
| `--tool-whitelist ` | comma-separated name prefixes — only tools whose name **starts with** one of the entries are proxied through the endpoint |
How the two compose:
* The whitelist matches the server's **original (unprefixed)** tool names, case-sensitively — `list` admits `list_pages` and `list_users` but not `my_list` or `List_all`. Changing the prefix never changes what the whitelist admits.
* Because entries are prefixes, the upstream can later add a new tool that matches one and it will be proxied automatically — even a full tool name as an entry also admits future extensions of it (`delete` admits a later `delete_all`). There is no exact-match mode; pick entries as specific as possible, and re-run `integrations check` after upstream changes to see exactly what is exposed.
* Entries are limited to letters, digits, dots, underscores, and hyphens (max 128 characters). A tool whose name uses other characters (`search$web`, non-ASCII names) can only be admitted through a shorter prefix entry that stops before the first unsupported character.
* The prefix applies to prompts too; the whitelist applies **only to tools**.
* `integrations check` and MCP clients connected to the profile endpoint see exactly the same prefixed, filtered names.
* A whitelist that matches nothing (e.g. a sentinel entry like `none`) blocks every tool from that server.
* The prefix keeps names valid MCP identifiers, but a very long upstream name plus a prefix can still exceed a client's own name limits.
***
## integrations rm
Remove a custom integration from a profile, deleting its stored credentials. Built-in integrations can't be removed — use `disconnect` instead.
```bash theme={"theme":"css-variables"}
machine0 integrations rm [-p ]
machine0 integrations rm deepwiki --yes # skip the confirmation prompt
```
***
## integrations connect
Connect (authenticate) an integration in a profile. `claude-code` and `codex` support two authentication methods, and `connect` asks which one to use — for `claude-code` the choices are **Anthropic Subscription** and **Anthropic API Key**; `codex` offers **API key** (its default) and account-based OAuth:
* **API key** (`claude-code`: "Anthropic API Key") — paste your own Anthropic (`sk-ant-...`) or OpenAI (`sk-...`) API key. This is the right choice for Anthropic Console (API-usage billing) accounts — create a key in your [Anthropic Console](https://console.anthropic.com) first. The CLI validates it against the provider first (a quick models-list call), then stores it encrypted. Usage bills to your provider account's API credits. No browser, no token refresh. A key the provider rejects outright (401) is refused; a permission-scoped key that can't list models (403 — e.g. an OpenAI restricted project key) prompts a confirm-to-store instead, and `integrations check` reports it as valid with a scoped-key note.
* **Account (OAuth)** (`claude-code`: "Anthropic Subscription") — the browser consent flow, using your Anthropic or ChatGPT account. `claude-code` asks you to paste the callback URL or `code#state` shown by Claude back into the CLI; the CLI performs the Anthropic token exchange locally and stores the OAuth login as-is. Choose this only for an account with a **Claude subscription** (Pro/Max/Team): an OAuth login from an Anthropic Console (API-billing) account authenticates but can't run `claude` on a VM — [`integrations check`](#integrations-check) flags such a login and tells you to reconnect with the API-key option. `codex` opens the same ChatGPT consent screen `codex login` uses and captures the callback automatically on `localhost:1455` — no pasting needed unless the browser can't reach the terminal's machine (CLI over SSH, port in use), in which case paste the callback URL from the address bar; its token exchange also runs locally.
`--auth ` skips the interactive chooser. In a non-interactive session, `--auth api-key` reads the key from stdin; without `--auth`, scripts get the OAuth behavior as before. There is deliberately no flag that takes the key as an argument (it would leak into shell history). In scripts, pass `--yes` too: it skips the replace-credentials confirmation when the integration is already connected (key rotation) and pre-confirms storing a key the models-list probe couldn't verify (a scoped key's 403, or a provider outage).
`github` opens the browser consent screen. `machine0-cli` connects immediately without a browser, and so do custom MCP servers that don't require auth.
```bash theme={"theme":"css-variables"}
machine0 integrations connect [-p ] [--yes] [--auth ]
```
```bash theme={"theme":"css-variables"}
machine0 integrations connect claude-code # asks: Anthropic Subscription or Anthropic API Key?
machine0 integrations connect codex --auth api-key # skip the chooser
echo "$OPENAI_API_KEY" | machine0 integrations connect codex --auth api-key --yes # non-interactive / key rotation
machine0 integrations connect github # browser consent
machine0 integrations connect machine0-cli # instant
```
Re-running `connect` on an already-connected integration asks for confirmation, then replaces the stored credentials with a fresh grant — including switching between API-key and account-based auth (the next VM create, resume, or `profiles deploy` injects the new mode and removes the old one's artifact). Connecting the same integration in another profile is independent — each profile holds its own credentials.
### GitHub repository access
Connecting `github` for the first time installs the machine0 GitHub App on your account or an organization, and GitHub's install screen lets you grant access to **all repositories** or **only the repositories you select**. The stored token can only reach what the installation covers.
* **Change repo access anytime** at [github.com/settings/installations](https://github.com/settings/installations) — changes take effect immediately, no reconnect needed. VMs already running with the profile's credentials follow along, since the token's access tracks the installation.
* **Add another organization without reconnecting.** Once the app is installed anywhere, re-running `connect` completes without showing GitHub's install screen again. To grant access to an additional org or account, use the install link that a passing `integrations check` prints (`github.com/apps//installations/new`) — the stored credentials reach new installations automatically, so nothing else is needed afterwards.
* **Organizations may require admin approval.** If your org does, the install becomes a request and the browser page tells you how to finish: either re-run `machine0 integrations connect` after an admin approves it, or — when the page says authorization is already complete — just run `machine0 integrations check` after approval. Until the admin approves, `integrations check` fails because the credentials reach no repositories.
* **Access is limited to accounts and orgs where the app is installed.** (The previous flow's `read:org` scope covered every org you belonged to; the App model does not.)
* **`gh gist` is not supported** — GitHub Apps have no access to the Gist API. Use a personal access token inside the VM if you need gists.
***
## integrations disconnect
Disconnect an integration, deleting its stored credentials in that profile. `github` and `machine0-cli` also get best-effort revocation on the provider side; `claude-code`, `codex`, and custom MCP credentials are simply deleted — for API-key connections in particular, the key stays valid at the provider until you revoke it in the Anthropic or OpenAI console. The integration shows as `disconnected` until you reconnect. Other profiles' connections are unaffected.
Disconnecting does **not** reach into VMs that were already provisioned with the profile — see the warning at the top of this page: credentials injected into running VMs, suspend snapshots, and custom images stay there until you remove them on the VM or destroy it.
Because the deletion is unrecoverable (reconnecting needs a fresh grant), the command asks for confirmation naming the integration and profile; pass `--yes` to skip it.
```bash theme={"theme":"css-variables"}
machine0 integrations disconnect [-p ] [--yes]
```
***
## integrations check
Check integration connections — one integration, or the whole profile at once. Exits non-zero when a check fails, so it's scriptable. (`integrations inspect` works as an alias.)
```bash theme={"theme":"css-variables"}
machine0 integrations check # check every integration in the current profile
machine0 integrations check # check one
machine0 integrations check -p work --json
```
### Checking one integration
The output shows a `status` line (this run's result) and a `message` line explaining it. Status collapses to two values: `connected` when the check passes, `disconnected` when it fails. When the run flips a previously-connected integration to failing, the status reads `connected -> disconnected` in red with the message in red too. The outcome is remembered: after a failed check the integration shows `disconnected` in red in `integrations ls` (with the failure and time on the detail view) until a check passes or you reconnect. `claude-code`'s and `codex`'s checks run locally in the CLI and report their outcomes back the same way. For MCP servers, the server's prompts and tools are listed (PROMPTS above TOOLS), with any configured [prefix and tool whitelist](#integrations-update) applied — exactly the names MCP clients see through the profile endpoint. One exception for OAuth-connected MCP servers: an expired access token is refreshed silently during the check, and if the server rejects the refresh (the token was revoked upstream), machine0 removes the dead credentials — the integration returns to `disconnected` and needs `integrations connect` again.
What each integration's live check does:
| Integration | Check |
| -------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| `claude-code` | calls the Anthropic API with the stored credential — an API key directly, or the Claude Code OAuth token (refreshing it first if needed). An OAuth login belonging to an Anthropic Console (API-billing) account is reported as failing, because that login can't run `claude` on a VM — reconnect and pick the Anthropic API Key option instead |
| `codex` | API-key mode calls the OpenAI API with the stored key; account mode verifies the stored ChatGPT OAuth tokens locally, refreshing them against OpenAI when near expiry (the refresh is the liveness probe) |
| `github` | calls the GitHub API and reports the authenticated login and which repositories are accessible; a passing check also prints the install link for granting access to another organization |
| `machine0-cli` | verifies the API key against machine0 |
| MCP servers | connects and lists the server's tools (shown as a table, one row per tool), silently refreshing stored OAuth tokens if they have expired |
### Checking the whole profile
Omitting the integration checks **every** integration in parallel, updating each one's stored status and last-checked time, then lists **all the prompts and tools the profile's MCP endpoint exposes** (PROMPTS above TOOLS) — one row per entry with the integration it comes from. The profile's own [prompts](/cli/prompts) are listed first, attributed to `profile`; per-integration prefixes and tool whitelists are applied. If two servers expose the same name, the endpoint serves the one from the last-listed integration; the other rows are marked `(shadowed)` — and a profile prompt always wins over a same-named upstream prompt.
Integrations are listed system-first, then MCP, each group alphabetical — the same order as `integrations ls` (`--json` keeps the server's own order, so key entries by `name`). Each row's status is `connected` (green), `connected -> disconnected` (red, when this run flipped a previously-connected integration to failing), or `disconnected`. A `disconnected` row is red when it fails the run and plain when it's benign (a built-in never connected, or a provider not configured on this server). A red row without the arrow — a custom MCP server failing, or an integration that was already failing before this run — still fails the run:
| State | Status | Exit code | Last checked |
| -------------------------------------------------------------- | --------------------------------- | ---------------------------- | ---------------------------------------------------------------------------------------- |
| connected, check passes | `connected` (green) | ok | updated |
| was connected, check fails this run | `connected -> disconnected` (red) | **non-zero** | updated |
| was connected, stored OAuth tokens rejected upstream (revoked) | `connected -> disconnected` (red) | **non-zero** | cleared (`--`) — the dead credentials are removed; reconnect with `integrations connect` |
| already failing / tokenless MCP fails | `disconnected` (red) | **non-zero** | updated when credentials are stored, else `--` |
| built-in integration never connected | `disconnected` (plain) | ok — reported, not a failure | `--` |
| provider not configured on this server | `disconnected` (plain) | ok — reported, not a failure | `--` |
`--json` returns the full per-integration array with real timestamps (the `claude-code` entry's timestamp comes from the CLI's local check, since that check runs on your machine). Each entry also carries a `previousStatus` field (`"connected"` or `"disconnected"`) — the integration's status *before* this run — so a script can detect a connected→disconnected flip. One freshness nuance for scripting: the profile-wide form returns each integration's `lastCheck*` fields as updated by *this* run, while the single-integration form shows the attributes as they were *before* its check ran — the `status` field is the live answer in both.

***
## ls
List all VMs.
```bash theme={"theme":"css-variables"}
machine0 ls
machine0 ls --json
```
***
## get
Show VM details: specs, pricing, IP, SSH key, timestamps. For an `UNAVAILABLE` VM, a `Status Info` row explains what happened and how to recover.
```bash theme={"theme":"css-variables"}
machine0 get
```
***
## start
Start a stopped or suspended VM. Suspended VMs are recreated from their snapshot with the same name, size, region, and key. Requires sufficient wallet balance.
Also retries a VM that is `UNAVAILABLE` (the provider was out of capacity) or `ERRORED` after a failed create or resume. If the size is still out of stock, the command fails immediately with a clear error instead of leaving the VM stuck. See [Machines → Out-of-capacity](/platform/vm-management#out-of-capacity-unavailable).
```bash theme={"theme":"css-variables"}
machine0 start
```
***
## stop
Stop a running VM.
```bash theme={"theme":"css-variables"}
machine0 stop
```
Stopped VMs still incur charges. Suspend or destroy to stop billing.
***
## reboot
```bash theme={"theme":"css-variables"}
machine0 reboot
```
***
## suspend
Snapshot the VM, delete the cloud instance, pay only image storage.
```bash theme={"theme":"css-variables"}
machine0 suspend [flags]
```
| Flag | Description |
| ----------- | ----------------- |
| `-y, --yes` | Skip confirmation |
The VM moves to `SUSPENDED`. Start again with `machine0 start`. Destroying a suspended VM also deletes its snapshot.
***
## rm
Destroy a VM.
```bash theme={"theme":"css-variables"}
machine0 rm [vm] [flags]
```
| Flag | Description |
| ----------- | ----------------- |
| `-a, --all` | Destroy all VMs |
| `-y, --yes` | Skip confirmation |
***
## ssh
SSH into a VM or run a remote command.
```bash theme={"theme":"css-variables"}
machine0 ssh [flags] [command...]
```
| Flag | Description | Default |
| ------------ | ------------------------------------------------- | ----------------------------- |
| `--username` | SSH username | VM default (usually `ubuntu`) |
| `-t, --tty` | Force pseudo-terminal allocation (like `ssh -tt`) | off |
```bash theme={"theme":"css-variables"}
machine0 ssh my-vm
machine0 ssh my-vm docker ps -a
machine0 ssh --username nix my-vm
machine0 ssh -t my-vm htop
```
Like `ssh`, flags go **before** the VM name — everything after it is the remote command, passed through verbatim (so remote flags like `ls -t` or `bash -lc 'your-command'` just work). If the VM is still starting, the CLI waits for SSH. If the VM has [disk](/cli/disks) attachments that are still coming up, the CLI briefly waits for those too before opening the session. Commands run under the remote user's default non-login shell; for login-shell initialization, use `machine0 ssh my-vm bash -lc 'your-command'`. Running a command doesn't allocate a terminal by default — pass `-t` for interactive programs like `htop`, `sudo` prompts, or TUI apps. Forcing a terminal merges stderr into stdout and rewrites line endings, so don't combine `-t` with output redirection.
***
## update
Update a VM's name, default SSH username, or SSH client initial command.
```bash theme={"theme":"css-variables"}
machine0 update [flags]
```
| Flag | Description |
| ------------------------------ | --------------------------------------------------------------------------------------------------- |
| `-n, --name` | New name (updates `mac0.io` endpoint) |
| `--default-ssh-username` | Default SSH username |
| `--ssh-client-initial-command` | Command run automatically when the VM is opened in the iPhone app's SSH client (pass `""` to clear) |
| `-y, --yes` | Skip confirmation |
```bash theme={"theme":"css-variables"}
machine0 update my-vm --ssh-client-initial-command "tmux attach || tmux new"
machine0 update my-vm --ssh-client-initial-command "" # clear
```
The SSH client initial command runs once per session, right after the shell loads — only in the iPhone app's terminal (requires app 1.2.2 or later; the web terminal and `machine0 ssh` don't run it). It shows in `machine0 get` under the SSH key. When you create an image from the VM, the command is copied onto the snapshot, and VMs created from that snapshot inherit it (override any time with `machine0 update`). Snapshots taken before the command was set are not retroactively updated. The command is stored and displayed in plain text — don't embed secrets in it; use [profile variables](/cli/env) for secrets.
***
## provision
Provision a VM with a Nix flake or Ansible playbook.
```bash theme={"theme":"css-variables"}
machine0 provision [flags]
```
| Flag | Description | Default |
| ------------ | --------------------------------------- | ------- |
| `--username` | SSH username | auto |
| `--dry-run` | Print planned actions without executing | |
`` can be a local directory, `flake.nix` path, remote flake ref, or `.yml` playbook. Append `#profile` to pick a specific NixOS configuration.
```bash theme={"theme":"css-variables"}
machine0 provision my-vm setup.yml
machine0 provision my-vm ./flake.nix#minimal
machine0 provision my-vm github:owner/repo#default
```

# Profiles
Source: https://docs.machine0.io/cli/profiles
CLI reference for profiles — named groups of integrations (Claude Code, Codex, GitHub, remote MCP servers), prompts, and env variables, each with its own MCP endpoint.
A profile is a named group of integrations, prompts, and env variables. Integrations connect your machine0 account to external services and store the resulting credentials encrypted — and because they live inside profiles, the same integration can be connected several times with different accounts (e.g. `github` as your work account in one profile and your personal account in another). Creating a VM with `machine0 new --profile ` injects the profile's credentials and env variables into it: `gh` is authenticated (`~/.config/gh/hosts.yml` + the git credential helper), `codex` is logged in (`~/.codex/auth.json`), and the profile's MCP endpoint is preconfigured for both Claude Code (`~/.claude.json`) and Codex (`~/.codex/config.toml`).
Each entity has its own command group: `profiles` manages the profile itself, [`integrations`](/cli/integrations) (alias `int`) its integrations, [`env`](/cli/env) (alias `vars`) its env variables, and [`prompts`](/cli/prompts) its prompt library.
New accounts start with a profile named `default`, so you can connect integrations and set variables without creating one first. You always have at least one profile — `profiles rm` refuses to remove your last remaining profile.
**Profile targeting** — the `integrations`, `env`, and `prompts` commands don't take a profile argument. They target the **current profile**, resolved as: the `-p/--profile` flag if given, else the `DEFAULT_PROFILE` setting (environment variable, then a `machine0.env` in the current directory, then `~/.machine0/machine0.env`), else `default`. Set it once with [`profiles use`](#profiles-use), override per command with `-p`, or pin it per project by adding `DEFAULT_PROFILE=` to a `machine0.env` in that directory (the CLI announces an active project pin on stderr). Every command names the profile it acted on.
```bash theme={"theme":"css-variables"}
machine0 integrations connect github # targets the current profile ("default" out of the box)
machine0 profiles new work --description "Work account"
machine0 profiles use work # subsequent commands target "work"
machine0 integrations new deepwiki --url https://mcp.deepwiki.com/mcp
machine0 env set NODE_ENV=production
machine0 prompts new code-review --body @review.md
machine0 env ls -p default # one-off override
machine0 profiles get # shows the current profile and where it's set
```
***
## The profile MCP endpoint
Each profile aggregates its MCP integrations behind one endpoint:
```
https://app.machine0.io/profiles//mcp
```
The endpoint speaks stateless Streamable HTTP (JSON responses, no sessions, no SSE) and serves the combined tools of every MCP integration in the profile — system integrations hold provider credentials and are not part of the aggregation. It also serves the profile's own [prompts](/cli/prompts) over the native MCP `prompts/list` / `prompts/get`, merged ahead of any prompts the upstream servers expose (on a name collision, the profile's prompt wins). Two ways to authenticate:
**OAuth** (interactive clients) — MCP clients supporting [RFC 9728](https://www.rfc-editor.org/rfc/rfc9728) discover the OAuth flow automatically. Claude Desktop, claude.ai connectors, and Claude Code handle this out of the box — just add the URL and approve the browser consent:
```bash theme={"theme":"css-variables"}
claude mcp add --transport http work-profile \
https://app.machine0.io/profiles/work/mcp
```
**API key** (programmatic) — pass your machine0 API key in the `x-api-key` header:
```bash theme={"theme":"css-variables"}
claude mcp add --transport http work-profile \
https://app.machine0.io/profiles/work/mcp \
--header "x-api-key: "
```
On a VM created (or deployed) with the profile, both values are already exported as [environment variables](/platform/profiles#environment-variables) — use `$MACHINE0_MCP_URL` and `$MACHINE0_API_KEY` instead of hardcoding them.
Profiles are an organizational boundary, not a security boundary: any of your API keys — and any MCP OAuth grant on your account — can call any of your profiles' endpoints.
***
## profiles ls
List your profiles with the number of VMs using each one and its description. The current profile is marked with `*`; if the current profile no longer exists (deleted, or a stale setting), the listing says so instead.
```bash theme={"theme":"css-variables"}
machine0 profiles ls
machine0 profiles ls --json
```
***
## profiles use
Set the current profile — the one `integrations`, `env`, and `prompts` commands target when `-p/--profile` isn't given. Validates the profile exists, then writes `DEFAULT_PROFILE` to `~/.machine0/machine0.env`. If an environment variable or a project `machine0.env` currently overrides the setting, the CLI warns and reports the write as not yet active.
```bash theme={"theme":"css-variables"}
machine0 profiles use work
machine0 config set DEFAULT_PROFILE=work # equivalent, without the existence check
```
To pin a profile for one project instead, add `DEFAULT_PROFILE=` to a `machine0.env` file in that directory — it beats the home config there and only there.
***
## profiles new
Create a profile. Aliased as `profiles create` and `profiles add`. Pass `--description` to describe the profile (it shows in `profiles ls` and `profiles get`).
Profile names follow the same rules as machine names (letters, digits, and dashes; max 63 characters) and are unique per account. Accounts are limited to 50 profiles, and a starter `default` profile counts toward that limit like any other (remove it once you have another profile if you need the slot back).
```bash theme={"theme":"css-variables"}
machine0 profiles new
machine0 profiles new --description "Work account with the org GitHub"
```
***
## profiles duplicate
Copy a profile — its description, env variables (secret markers included), prompts, and integrations — into a new profile. Aliased as `profiles copy`.
Each integration is copied with its description, [tool/prompt prefix](/cli/integrations#integrations-update), and tool whitelist intact, so the copy's MCP endpoint exposes the same names as the source. Copied integrations arrive **disconnected**: credentials are never copied, so reconnect any that need them in the new profile with [`integrations connect`](/cli/integrations#integrations-connect). (Custom MCP integrations that don't require credentials keep working without a reconnect.) Without a target name the copy is named `-copy`, then `-copy-2`, `-copy-3`, … if taken; an explicit target name must be free. Copies count toward the 50-profile account limit.
```bash theme={"theme":"css-variables"}
machine0 profiles duplicate # creates -copy
machine0 profiles duplicate
machine0 profiles duplicate work backup --json
```
***
## profiles update
Update a profile's settings. Pass `--name` to rename it, `--description` to change
the description (pass an empty string to clear it). You can pass both at once.
```bash theme={"theme":"css-variables"}
machine0 profiles update --name personal # rename
machine0 profiles update --description "New description"
machine0 profiles update --description "" # clear it
```
Renaming preserves the profile's variables, secrets, and connected integrations —
it only changes the name. If you rename the profile you're currently using
(your `DEFAULT_PROFILE`), the CLI updates that setting so profile-scoped commands
keep working.
Renaming is **not retroactive to machines you've already provisioned.** A
profile's MCP endpoint URL (`/profiles//mcp`) and any MCP URL already
injected into a running machine keep the old name until you redeploy the profile
with [`profiles deploy`](#profiles-deploy) (or resume/recreate the machine).
External tools that hardcode the old MCP URL will also need updating.
***
## profiles deploy
Deploy a profile onto a **running** VM — wipes the previously injected profile's credentials and env variables off the machine and injects this profile's instead. The profile is the current one, or pass `-p/--profile`. Because it replaces what's on the machine, the command asks for confirmation naming both the profile and the machine; pass `--yes` to skip it (required in scripts and with `--json`).
Deployment happens server-side over SSH; integration secrets never pass through your terminal. Works on both Ubuntu and NixOS machines (NixOS needs a current image version; older images apply credentials but shells won't see env vars until the image updates).
New env vars and credentials apply to new sessions — running shells and agent processes (`claude`, `codex`) keep the old state until restarted.
```bash theme={"theme":"css-variables"}
machine0 profiles deploy [-p ] [--yes]
machine0 profiles deploy my-vm # deploys the current profile
machine0 profiles deploy my-vm -p work --yes --json
```
***
## profiles get
Show a profile's details — its description and MCP connection string, its integrations (built-in and custom) with their connection status, its prompts (with the start of each body), and its environment variables.
With no argument it shows the **current profile**, plus a line saying where the setting comes from (the `DEFAULT_PROFILE` environment variable, a project `machine0.env`, the home config, or the built-in `default`).
```bash theme={"theme":"css-variables"}
machine0 profiles get # current profile + its source
machine0 profiles get work --json
```
For a single integration's details see [`integrations get`](/cli/integrations#integrations-get); for a prompt's body see [`prompts get`](/cli/prompts#prompts-get); for the variables alone see [`env ls`](/cli/env#env-ls).
***
## profiles rm
Remove a profile. This deletes its integrations and their stored credentials (a connected `machine0-cli` key is revoked), removes its prompts, and its MCP endpoint stops working. Your last remaining profile cannot be removed — create another profile first. Removing the current profile warns in the confirmation: run `profiles use` afterwards or commands fall back to a profile that no longer exists (they fail with a pointer at `profiles use`).
```bash theme={"theme":"css-variables"}
machine0 profiles rm
machine0 profiles rm --yes # skip the confirmation prompt
```
# Prompts
Source: https://docs.machine0.io/cli/prompts
CLI reference for prompts — named text templates stored on a profile and served over its MCP endpoint as slash commands.
A prompt is a named text template stored on a [profile](/cli/profiles) and served over the profile's MCP endpoint. Commands target the [current profile](/cli/profiles#profiles-use); pass `-p/--profile` to target another one. Claude Code surfaces MCP prompts as slash commands — `/mcp____`, where `` is whatever name you gave the connection (`machine0` on VMs, which wire the profile endpoint automatically). One `prompts new` makes a prompt available in every Claude surface connected to the profile — unlike machine-local `.claude/commands` files, the library follows the profile everywhere, and edits propagate without touching any machine.
```bash theme={"theme":"css-variables"}
machine0 prompts new code-review --body @review.md -p work
claude mcp add --transport http work https://app.machine0.io/profiles/work/mcp
# in Claude Code: type "/" → /mcp__work__code-review
```
Two propagation rules: **adds and removes** appear in a client on its next connect (Claude Code discovers prompts when it connects — reconnect the server or restart the session to pick up a new prompt); **body and description edits are live** on the next invocation, no reconnect needed.
Prompt names follow the same rules as integration names (letters, digits, and dashes; max 63 characters, unique per profile case-insensitively). Each profile holds up to 50 prompts, bodies up to 64KB, stored encrypted at rest. Prompts in v1 take no arguments — invoking the slash command inserts the body verbatim; argument templating is a planned follow-up.
***
## prompts ls
List a profile's prompts with their descriptions and the start of each body (truncated to the terminal width).
```bash theme={"theme":"css-variables"}
machine0 prompts ls
machine0 prompts ls -p work --json
```
***
## prompts get
Show a prompt's name, description, and full body — word-wrapped to the terminal width.
```bash theme={"theme":"css-variables"}
machine0 prompts get [-p ]
machine0 prompts get code-review --json
```
***
## prompts new
Add a prompt to a profile. Aliased as `prompts create` and `prompts add`. Takes a `--body` and an optional `--description`. Adding a name that already exists errors with a pointer at `prompts update`.
The `--body` flag takes three input modes (curl's `@` convention), and omitting it in a terminal opens `$EDITOR` like `git commit`:
```bash theme={"theme":"css-variables"}
machine0 prompts new ship --body "Run /ship and fix anything that fails."
machine0 prompts new code-review --body @./prompts/review.md
cat review.md | machine0 prompts new code-review --body @-
machine0 prompts new standup # opens $EDITOR
machine0 prompts new code-review --description "review SOP" --body @review.md -p work
```
***
## prompts update
Update a prompt's body or description. Pass an empty string to clear the description. With no flags in a terminal, opens `$EDITOR` pre-filled with the current body.
```bash theme={"theme":"css-variables"}
machine0 prompts update code-review --body @review-v2.md
machine0 prompts update code-review # $EDITOR pre-filled with the current body
```
***
## prompts rm
Remove a prompt from a profile. It disappears from connected clients on their next connect.
```bash theme={"theme":"css-variables"}
machine0 prompts rm [-p ]
machine0 prompts rm code-review --yes # skip the confirmation prompt
```
# Skills
Source: https://docs.machine0.io/cli/skills
CLI reference for installing machine0 agent skills into your coding agents.
machine0 publishes agent skills at [fdmtl/machine0-skills](https://github.com/fdmtl/machine0-skills) — reusable instructions your coding agents (Claude Code, Codex) can invoke; in Claude Code they appear as slash commands. Installation is handled by the open [skills CLI](https://github.com/vercel-labs/skills) under the hood (via `npx`, so npm must be installed); skills are installed globally, in the universal `~/.agents/skills` directory (which Codex reads directly) with a `~/.claude/skills` link for Claude Code; an install targeting a single agent only touches that agent's directory.
The first skill is `/create-machine`: describe a machine in plain English ("a server running postgres on docker managed with a Dockerfile") and the agent scaffolds a git-versioned NixOS project, boots a machine0 VM from it, verifies it, and leaves it running.
## install
```bash theme={"theme":"css-variables"}
machine0 skills install [flags]
```
Prompts for which agents to install to. Re-running updates already-installed skills.
| Flag | Description |
| ------------- | ----------------------------------------------------------------- |
| `-a, --agent` | Target agents, skips the prompt: `claude-code`, `codex`, or `all` |
```bash theme={"theme":"css-variables"}
machine0 skills install # interactive agent selection
machine0 skills install --agent all # both agents, no prompt
machine0 skills install -a claude-code # one agent (also for scripts/CI)
```
***
## uninstall
```bash theme={"theme":"css-variables"}
machine0 skills uninstall [flags]
```
Removes the machine0 skills (by their names, e.g. `create-machine`) from the selected agents. Other skills you have installed are untouched — unless one happens to share a machine0 skill name.
| Flag | Description |
| ------------- | ----------------------------------------------------------------- |
| `-a, --agent` | Target agents, skips the prompt: `claude-code`, `codex`, or `all` |
```bash theme={"theme":"css-variables"}
machine0 skills uninstall -a all
```
# Sync
Source: https://docs.machine0.io/cli/sync
CLI reference for syncing files between your local machine and VMs.
Uses rsync over SSH. Requires rsync on both ends (pre-installed on all machine0 images and macOS).
## push
```bash theme={"theme":"css-variables"}
machine0 sync push :[remote-path] [flags]
```
| Flag | Description |
| ------------- | -------------------------------------------- |
| `--username` | SSH username |
| `--dry-run` | Show what would transfer |
| `--delete` | Delete remote files that don't exist locally |
| `-w, --watch` | Watch for changes and re-sync automatically |
Remote path defaults to `~/` if omitted.
```bash theme={"theme":"css-variables"}
machine0 sync push ./src myvm:~/app
machine0 sync push ./src myvm:~/app --watch
machine0 sync push ./project myvm:~/project --delete
```
***
## pull
```bash theme={"theme":"css-variables"}
machine0 sync pull :[remote-path] [flags]
```
| Flag | Description |
| ------------ | ----------------------------------------- |
| `--username` | SSH username |
| `--dry-run` | Show what would transfer |
| `--delete` | Delete local files that don't exist on VM |
```bash theme={"theme":"css-variables"}
machine0 sync pull myvm:~/app ./src
```
# Running Agents with Profiles
Source: https://docs.machine0.io/examples/coding-agents
Install machine0
```bash theme={"theme":"css-variables"}
curl -LsSf https://machine0.io/install.sh | sh
```
Run agents inside VMs with root access, dedicated resources, and no local machine risk. Use [profiles](/platform/profiles) to inject credentials, MCP servers, prompts, and env variables into the VMs so your agents hit the ground running.
```bash theme={"theme":"css-variables"}
# Authenticate Claude Code, Codex & GitHub
machine0 integrations connect claude-code
machine0 integrations connect codex
machine0 integrations connect github
# Add your MCPs
machine0 integrations new linear --url https://mcp.linear.app/mcp
machine0 integrations connect linear # triggers the OAuth flow
# Configure env variables
machine0 env set MY_SECRET_KEY=... --secret
# Add a prompt
machine0 prompts new build-feature --body "Query Linear for..."
# Create a new VM with the profile
machine0 new myvm --profile default
machine0 ssh myvm
# Claude Code is authenticated and has your MCPs & prompts in context
claude
```
Commands target your `default` profile out of the box; use `-p ` to target another. When you're done, `machine0 sync pull` brings the work back locally and `machine0 suspend myvm` stops compute billing.
# Powerful VMs on Demand
Source: https://docs.machine0.io/examples/compute
Install machine0
```bash theme={"theme":"css-variables"}
curl -LsSf https://machine0.io/install.sh | sh
```
Create stable, powerful VMs in your region. Ideal for offloading compute-heavy tasks like compilation, test runs, or automated research instead of grinding your laptop.
```bash theme={"theme":"css-variables"}
machine0 new buildbox --size 4xl --region us-east # 32 vCPU, 128 GB RAM
machine0 ssh buildbox
machine0 suspend buildbox # suspend, stop compute billing
machine0 start buildbox # pick up where you left off
```
Sizes go from 1 vCPU / 1 GB up to 60 vCPU / 240 GB, plus [GPUs](/introduction/pricing) from RTX 4000 Ada to 8x H200.
# Running Hermes
Source: https://docs.machine0.io/examples/hermes
Install machine0
```bash theme={"theme":"css-variables"}
curl -LsSf https://machine0.io/install.sh | sh
```
Create a VM, install Hermes, and give it isolated credentials.
```bash theme={"theme":"css-variables"}
machine0 new hermes --image nixos-25-11-hermes --size medium # on NixOS
machine0 new hermes --image ubuntu-24-04-hermes --size medium # on Ubuntu
machine0 ssh hermes
# Install and configure Hermes inside the VM
hermes setup
# Back up and suspend when done
machine0 sync pull hermes:~/ ~/Backups/hermes
machine0 suspend hermes
```
# Hosting
Source: https://docs.machine0.io/examples/hosting
Install machine0
```bash theme={"theme":"css-variables"}
curl -LsSf https://machine0.io/install.sh | sh
```
Every VM gets a static IP and authenticated HTTPS at `.mac0.io`, and persists until stopped, suspended, or removed, with 99.99% uptime across 5 regions. Good for hosting web apps, databases, or anything that needs a stable address.
```bash theme={"theme":"css-variables"}
machine0 new webserver --image nixos-25-11-loaded --size small
claude -p "Use machine0 to start a webserver on port 80 on the webserver VM"
# Get the VM's IP
machine0 get webserver
# Open the authenticated HTTPS endpoint
open https://webserver.mac0.io
```
Or use the one-liner, which creates a small webserver VM and SSHes in:
```bash theme={"theme":"css-variables"}
machine0 use webserver
```
# Reproducible NixOS Builds
Source: https://docs.machine0.io/examples/nixos
Install machine0
```bash theme={"theme":"css-variables"}
curl -LsSf https://machine0.io/install.sh | sh
```
Define your OS as code with NixOS. Use the `/create-machine` skill to generate the nix code, boot a VM from it, and snapshot it so you can stamp out as many clones as you want.
```bash theme={"theme":"css-variables"}
# Install the /create-machine skill
machine0 skills install
# Use the skill to create a machine
claude -p "/create-machine a server that auto-starts claude code in tmux on boot"
# Code is auto-generated
ls -l claude-in-tmux/
# SSH in and you're ready
machine0 ssh claude-in-tmux
tmux attach
```
Or manually:
```bash theme={"theme":"css-variables"}
# Create a NixOS VM
machine0 new devbox --image nixos-25-11-loaded --size large
# Clone the flake, modify the config, rebuild
git clone https://github.com/fdmtl/machine0-nixos.git ./
claude -p "Add postgres to the loaded profile"
machine0 provision devbox ./flake.nix#loaded
# SSH in and start working
machine0 ssh devbox
# Create a golden master snapshot
machine0 stop devbox
machine0 images new devbox devbox-gm
# Need a clean or larger VM? Spin one up from the image
machine0 rm devbox
machine0 new devbox --image devbox-gm --size xxl
```
## NixOS on GPUs
The `nixos-25-11-nvidia` image ships the NVIDIA driver stack, CUDA, and the container toolkit pre-baked — no `nixos-rebuild` needed. It runs on the supported NVIDIA GPU sizes: `gpu-4000ada-1`, `gpu-6000ada-1`, and `gpu-h100-1` (AMD `gpu-mi300x-*` sizes are not supported). The SSH user is `nix`.
```bash theme={"theme":"css-variables"}
# GPU-only system images are hidden by default — list them with --all
machine0 images ls --all
# Create a GPU VM from the NVIDIA image
machine0 new ml --image nixos-25-11-nvidia --size gpu-h100-1
# SSH in and run a GPU container — drivers and CUDA are already there
machine0 ssh ml
docker run --rm --gpus all nvidia/cuda:12.4.0-base-ubuntu22.04 nvidia-smi
```
# Running OpenClaw
Source: https://docs.machine0.io/examples/openclaw
Install machine0
```bash theme={"theme":"css-variables"}
curl -LsSf https://machine0.io/install.sh | sh
```
One command to create an OpenClaw VM and SSH in:
```bash theme={"theme":"css-variables"}
machine0 use openclaw
```
Or manually:
```bash theme={"theme":"css-variables"}
machine0 new openclaw --image nixos-25-11-openclaw --size medium # on NixOS
machine0 new openclaw --image ubuntu-24-04-openclaw --size medium # on Ubuntu
machine0 ssh openclaw
# Start the onboarding flow
openclaw onboard --install-daemon
# Back up and suspend when done
machine0 sync pull openclaw:~/.openclaw/ ~/Backups/openclaw
machine0 suspend openclaw
```
# FAQ
Source: https://docs.machine0.io/introduction/faq
**Where do VMs run?** DigitalOcean infrastructure across five regions (New York, San Francisco, London, Amsterdam, Singapore).
**Are stopped VMs billed?** Yes. Stopped VMs reserve cloud resources and bill at full rate. [Suspend](/platform/vm-management#suspend-vs-stop-vs-destroy) to pay only image storage, or destroy to stop billing entirely.
**What if I run out of credits?** Running machines are snapshotted and destroyed. Snapshots are retained -- top up and recreate. [Disks](/cli/disks) are kept (they hold your data) and keep billing until you remove them; recreated VMs don't reattach them automatically — pass `--attach disk:` again. [Auto-topup](/introduction/pricing#wallet) prevents this and is on by default once you have a saved card; you can turn it off from the billing page in the web dashboard.
**What tools are pre-installed?** The `ubuntu-24-04-loaded` image includes Docker, Node.js, Python, Go, Rust, Bun, Claude Code, Codex, OpenCode, tmux, zoxide, fzf, ripgrep, and bat. See [Images](/platform/images).
**Can I export my data?** Yes. SSH in and copy anything, or use `machine0 sync pull`. With NixOS, your OS config is portable to any NixOS host.
**Can I use my own SSH key?** Yes, that's the default. The CLI registers your `~/.ssh/id_rsa.pub` on first use. See [SSH](/platform/ssh).

# Powerful & Persistent VMs from the CLI
Source: https://docs.machine0.io/introduction/overview
```bash theme={"theme":"css-variables"}
curl -LsSf https://machine0.io/install.sh | sh
machine0 new my-vm
machine0 ssh my-vm
```
machine0 provides persistent cloud VMs, designed for long-running agents. One command gives you (or your agent) an SSH-ready VM with dedicated CPU/RAM/GPUs, [modern agents and tooling](/platform/images), a static IP, and HTTPS at `.mac0.io`. VMs stay on until you stop or suspend them, and everything is billed by the minute. Every command has `--json`, and a [remote MCP server](/mcp/overview) lets agents manage their own fleet: spin up a box for a build, snapshot it, tear it down.
## What you get
* **Powerful Computers:** 1-60 vCPU, up to 240 GB RAM. Not shared. Built for compute-heavy workloads, with a 99.99% uptime SLA.
* **GPUs:** H100, H200, MI300X, L40S, RTX 4000/6000 Ada. From \$0.836/hr, up to 8x H200.
* **Suspend & resume:** pause an idle machine, stop paying for compute, resume exactly where it left off. Pay only image storage while suspended.
* **Snapshot & clone:** configure one machine, image it, spin up identical clones. Images are versioned.
* **Disks:** persistent block storage volumes — [create one](/cli/disks) with `machine0 disks new`, attach it to a VM at creation with `--attach disk: path:` or to a running VM with `disks attach`, and keep the data across suspend/resume and VM destruction. \~\$0.1667/GB/month.
* **Profiles:** bundles of MCP servers, integrations (GitHub, Claude Code, Codex), prompts, and env variables, injected at VM creation. This gives each agent exactly the capabilities you choose and nothing else.
* **NixOS or Ubuntu:** NixOS is first-class: declarative, reproducible machines provisioned with [Nix flakes](https://github.com/fdmtl/machine0-nixos). Ubuntu comes with [Ansible](https://github.com/fdmtl/machine0-ubuntu). All images are open source.
* **NixOS on GPUs:** the `nixos-25-11-nvidia` image ships NVIDIA drivers, CUDA, and GPU containers pre-installed — no driver setup — on supported NVIDIA GPU sizes.
* **Static IPs & HTTPS:** every VM gets a public IP and authenticated HTTPS at `.mac0.io`.
* **In-browser SSH terminal:** one click from the web dashboard for VMs with a managed key — no local setup needed.
* **Agent skills:** [`machine0 skills install`](/cli/skills) adds machine0's skills to your local coding agents (Claude Code, Codex). The first, `/create-machine`, turns a plain-English description into a git-versioned NixOS project and a running VM built from it.
* **File sync:** `sync push` and `sync pull` with `--watch`.
* **5 regions:** New York, San Francisco, London, Amsterdam, Singapore. Same price everywhere.
* **Per-minute billing:** starts at \$0.013/hr. No commitments, refundable credits.

```bash theme={"theme":"css-variables"}
machine0 sizes
```
## CPU
| Size | vCPU | RAM | Disk | \$/hour | \~\$/month |
| ------------- | ---- | ------ | ------ | ------- | ---------- |
| `small` | 1 | 1 GB | 25 GB | \$0.013 | \$9 |

| `xl` | 4 | 8 GB | 160 GB | \$0.104 | \$76 |
| `xxl` | 8 | 16 GB | 320 GB | \$0.208 | \$152 |
| `large-nvme` | 2 | 4 GB | 80 GB | \$0.061 | \$45 |
| `xl-nvme` | 4 | 8 GB | 160 GB | \$0.121 | \$88 |
| `xxl-nvme` | 8 | 16 GB | 320 GB | \$0.243 | \$177 |
| `xl-premium` | 4 | 8 GB | 50 GB | \$0.236 | \$172 |
| `xxl-premium` | 8 | 16 GB | 100 GB | \$0.473 | \$345 |
| `xxxl` | 16 | 64 GB | 200 GB | \$0.825 | \$602 |
| `4xl` | 32 | 128 GB | 480 GB | \$1.980 | \$1,445 |

| `6xl` | 60 | 240 GB | 900 GB | \$3.714 | \$2,711 |
The `-nvme` sizes run on newer-generation CPUs with NVMe storage for
significantly higher disk IOPS — same vCPU, RAM, and disk as their regular
counterparts.
The `-premium` sizes are dedicated (not shared) vCPUs, the fastest single-thread performance we offer.
## GPU
| Size | GPU | VRAM | vCPU | RAM | Disk | \$/hour |
| --------------- | --------------- | -------- | ---- | -------- | ------ | -------- |
| `gpu-4000ada-1` | 1x RTX 4000 Ada | 20 GB | 8 | 32 GB | 500 GB | \$0.836 |
| `gpu-l40s-1` | 1x L40S | 48 GB | 8 | 64 GB | 500 GB | \$1.727 |
| `gpu-6000ada-1` | 1x RTX 6000 Ada | 48 GB | 8 | 64 GB | 500 GB | \$1.727 |
| `gpu-mi300x-1` | 1x MI300X | 192 GB | 20 | 240 GB | 720 GB | \$2.849 |
| `gpu-h100-1` | 1x H100 | 80 GB | 20 | 240 GB | 720 GB | \$4.851 |

## Regions
| Region | Location |
| --------- | ------------- |
| `us-east` | New York |
| `us-west` | San Francisco |
| `uk` | London |
| `eu` | Amsterdam |
| `asia` | Singapore |
GPU sizes are available in `us-east`, `uk`, `eu`, and `asia` — not `us-west`. GPU VMs are placed on GPU capacity within the region, which may be a nearby datacenter (for example, `us-east` GPU VMs may run in Toronto).
## What gets billed
| Resource | Rate | Notes |
| --------- | ------------------------------------------------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Machines | Per-minute at the size rate | Billed while running **and stopped** (resources reserved). [Suspend](/platform/vm-management#suspend-vs-stop-vs-destroy) to stop machine billing. |
| Images | \$0.078/GB/month, billed hourly as it accrues | Charged for snapshots and suspended VM images. |
| Bandwidth | \$0.01/GiB overage | 1-10 TB free allowance per size. |
| Disks | \~\$0.1667/GB/month, billed hourly as it accrues | Persistent [block storage volumes](/cli/disks). Billed while `READY` — including when the VM they're attached to is suspended — until removed with `disks rm`. |
## Wallet
```bash theme={"theme":"css-variables"}
machine0 account # check balance
machine0 topup --amount 10 # add funds (minimum $5)
```
Unused credits are refundable. When your balance can't cover 1 hour of runtime, running machines are snapshotted and destroyed. Snapshots are retained -- top up and recreate from them.
Auto-topup is on by default: once you have a saved card, your wallet is automatically recharged before machines are suspended. Recharges run at most once every 6 hours, unless your balance is critically low. You can turn it off from the billing page in the web dashboard.
# Quickstart
Source: https://docs.machine0.io/introduction/quickstart
## Install
```bash theme={"theme":"css-variables"}
curl -LsSf https://machine0.io/install.sh | sh
```
Or via npm: `npm install -g @machine0/cli` (requires Node.js ≥ 20.12)
## Create a VM
```bash theme={"theme":"css-variables"}
machine0 new my-vm
```
Override defaults with `--image`, `--size`, `--region`. Change defaults permanently with `config set` ([configuration](/platform/configuration)).
## SSH in
```bash theme={"theme":"css-variables"}
machine0 ssh my-vm
```
The VM has a dedicated IP, HTTPS at `https://my-vm.mac0.io`, and root access via sudo. The CLI uses your `~/.ssh/id_rsa.pub` by default. See [SSH](/platform/ssh).
## Manage VMs
```bash theme={"theme":"css-variables"}
machine0 ls # list VMs
machine0 get my-vm # details
machine0 stop my-vm # stop (still billed -- resources reserved)
machine0 suspend my-vm # snapshot + destroy (pay only storage)
machine0 start my-vm # start a stopped or suspended VM
machine0 rm my-vm # destroy permanently
```
## Snapshot and clone
```bash theme={"theme":"css-variables"}
machine0 images new my-vm my-snapshot
machine0 rm my-vm
machine0 new my-clone --image my-snapshot --size xxl
```
See [Images](/platform/images).

| `name` | string | yes |
***
## vm\_create
Create a VM. Provisioning takes 1-3 minutes (longer for large images). Poll `vm_get` until status changes from `CREATING` to `RUNNING`.
| Parameter | Type | Required | Description |
| -------------- | ------- | -------- | ---------------------------------------- |
| `name` | string | yes | VM name |
| `size` | string | yes | See [sizes](/mcp/sizes) |
| `region` | string | yes | `us-east`, `us-west`, `uk`, `eu`, `asia` |
| `imageName` | string | yes | Image name |
| `sshKeyId` | UUID | no | Uses default key if omitted |
| `imageVersion` | integer | no | Specific version |
To use `ssh_exec`, provide a managed key ID in `sshKeyId`.
***

# MCP
Source: https://docs.machine0.io/mcp/overview
Connect AI agents to machine0 using the Model Context Protocol.
```
POST https://app.machine0.io/mcp
```
Streamable HTTP transport, stateless, JSON responses. Gives agents the same capabilities as the CLI.
## Authentication
**OAuth** (interactive clients) -- MCP clients supporting [RFC 9728](https://www.rfc-editor.org/rfc/rfc9728) discover endpoints automatically. Claude Desktop, claude.ai custom connectors, and Claude Code handle this out of the box.
**API key** (programmatic) -- pass in the `x-api-key` header. Generate keys from your account settings. On a VM created (or deployed) with a profile, a ready-made pair is already exported as env vars: `MACHINE0_MCP_URL` (the profile's MCP endpoint) and `MACHINE0_API_KEY` (a key that authenticates against it) — see [profile environment variables](/platform/profiles#environment-variables).
## Setup
### Claude Desktop
Add to `~/Library/Application Support/Claude/claude_desktop_config.json`:
```json theme={"theme":"css-variables"}
{
"mcpServers": {
"machine0": {
"url": "https://app.machine0.io/mcp"
}
}
}
```
### Claude Code
```bash theme={"theme":"css-variables"}
claude mcp add --transport http machine0 https://app.machine0.io/mcp
```
### Other clients
Any MCP client with Streamable HTTP transport support. Point at `https://app.machine0.io/mcp` with OAuth or an API key header. Browser-based clients work too via OAuth — the OAuth and MCP endpoints are CORS-enabled, so tools like the [MCP Inspector](https://github.com/modelcontextprotocol/inspector) can connect and complete the OAuth flow directly from the browser. (The `x-api-key` header is for non-browser clients; browsers authenticate with OAuth.)
## Tools
| Category | Tools |
| ------------------------- | ----------------------------------- |
| [Machines](/mcp/machines) | 10 -- create, manage, destroy VMs |
| [Images](/mcp/images) | 10 -- snapshot VMs, manage versions |
| [SSH Keys](/mcp/keys) | 7 -- public and managed keys |
| [SSH Exec](/mcp/ssh) | 1 -- run commands on VMs remotely |
| [Sizes](/mcp/sizes) | 1 -- list sizes and pricing |
## Managed keys
To use `ssh_exec`, VMs must be created with a managed key (server-side keypair). Create one with `ssh_key_create_managed`, then pass its ID when creating VMs. VMs with public keys cannot use `ssh_exec`.
# Sizes
Source: https://docs.machine0.io/mcp/sizes
MCP tool for listing VM sizes and pricing.
## size\_list
List available sizes with pricing and regional availability.
**Parameters:** None
Returns an array of size objects:
| Field | Description |
| ------------------- | ----------------------------------------------------------- |
| `size` | Size identifier |
| `vcpu` | Virtual CPUs |
| `ramGb` | RAM in GB |
| `diskGb` | Disk in GB |
| `pricePerHourMicro` | Price per hour in micro-units (divide by 1,000,000 for USD) |
| `gpu` | GPU type or `null` |
| `regions` | Available regions |
See [Pricing](/introduction/pricing) for the full table.
# SSH Exec
Source: https://docs.machine0.io/mcp/ssh
Execute commands on VMs remotely via MCP.
## ssh\_exec
Run a command on a VM via SSH. Returns stdout, stderr, and exit code. No interactive commands or stdin.
| Parameter | Type | Required | Description |
| -------------- | ------- | -------- | ----------------------------------------------------- |
| `machine_id` | UUID | no | VM ID (provide one of `machine_id` or `machine_name`) |
| `machine_name` | string | no | VM name |
| `command` | string | yes | Shell command (max 65,536 chars) |
| `timeout` | integer | no | Seconds (default: 30, max: 300) |
| `username` | string | no | SSH username override |
Requires a managed SSH key. VMs created with public keys will fail. If you need to switch, destroy the VM and recreate it with a managed key ID in `sshKeyId`.
# Configuration
Source: https://docs.machine0.io/platform/configuration
## View and set
```bash theme={"theme":"css-variables"}
machine0 config get
machine0 config set DEFAULT_VM_SIZE=large DEFAULT_VM_REGION=us-east
```
## Settings
| Setting | Default | Description |
| --------------------------- | ------------------------- | --------------------------------------------------------------------------------------------------------- |
| `SSH_KEY_PATH` | `~/.ssh` | SSH key storage directory |
| `DEFAULT_VM_SIZE` | `small` | Default size for `machine0 new` |
| `DEFAULT_VM_REGION` | `eu` | Default region |
| `DEFAULT_VM_IMAGE` | `ubuntu-24-04-loaded` | Default image |
| `DEFAULT_PROFILE` | `default` | Profile targeted by the `profiles`/`integrations`/`prompts`/`env` commands when `-p/--profile` is omitted |
| `SERVER_URL` | `https://app.machine0.io` | API endpoint |
| `SESSION_FILE_PATH` | `~/.machine0/auth-token` | Session token path |
| `USE_EXPERIMENTAL_FEATURES` | `false` | Show hidden command groups (currently none — reserved for future experimental features) |
## Loading order
Highest priority wins:
1. Environment variables
2. Project config (`./machine0.env`)
3. Home config (`~/.machine0/machine0.env`)
4. Built-in defaults
An environment variable set to an empty string counts as unset — a stray `export SERVER_URL=` won't override your `machine0.env` value or fall back to the built-in default.
`config get` labels where each value comes from: `(env)` for environment variables, `**` for the project config, `*` for the home config. Unmarked values are built-in defaults.
## Project config
Drop a `machine0.env` in your project directory to override defaults per-project. `config set` always writes to the home config, and warns per key when the saved value is currently shadowed by an environment variable or the project config.
## Hidden command groups
There are currently no experimental command groups — `USE_EXPERIMENTAL_FEATURES` is reserved for the next one and has no effect today. It's still toggleable:
```bash theme={"theme":"css-variables"}
machine0 config set USE_EXPERIMENTAL_FEATURES=true
```
The flag also works as an environment variable (`export USE_EXPERIMENTAL_FEATURES=true`), but not via a project `machine0.env`.
## API token
For automation, set `MACHINE0_API_TOKEN` instead of using `machine0 login`:
```bash theme={"theme":"css-variables"}
export MACHINE0_API_TOKEN=m0_tok_...
```
# Disks (Beta)
Source: https://docs.machine0.io/platform/disks
Disks are persistent block storage volumes that live independently of any VM. Attach one to a VM at an absolute path, and the data survives suspend, resume, and even destroying the VM.
A disk lives in one region and attaches to one VM at a time. Once mounted, it's owned by the VM's login user. Disks are durable but not backed up. Removing a disk deletes all of its data, permanently.
## Lifecycle
| State | Billed? | Notes |
| ---------- | ------- | ------------------------------------------------------------------- |
| `CREATING` | No | Provisioning, usually seconds |
| `READY` | Yes | Attachable, whether attached or not |
| `ERRORED` | No | Provisioning failed. `disks get` shows why; `disks rm` to clean up. |
## Create a disk
```bash theme={"theme":"css-variables"}
$ machine0 disks new data --size 50 --region us-west
```
## Attach at VM creation
```bash theme={"theme":"css-variables"}
machine0 new dev1 --attach disk:data path:/data
```
## Attach to a running VM
```bash theme={"theme":"css-variables"}
$ machine0 disks attach data dev1 --path /data
```
Detach it again with `machine0 disks detach data`.
## See your disks
```bash theme={"theme":"css-variables"}
$ machine0 disks ls
┌───────────────────────────────────────────────────┐
│ Name Status Size Region Attached To │
│ data READY 50 GB us-west dev1 │
└───────────────────────────────────────────────────┘
```
## Limits
* 10 disks per account, 5 per VM
* 10–16384 GB per disk
* A disk attaches only to VMs in its own region
* Mount paths must be absolute and can't nest inside one another
* Attaching to a running VM requires a managed SSH key
* Not yet supported on GPU sizes or NixOS VMs
## Billing
\~\$0.1667/GB/month, billed hourly while the disk is `READY` — attached or not. See [Pricing](/introduction/pricing).

# Images
Source: https://docs.machine0.io/platform/images
## System images
| Image | Description |
| ----------------------- | -------------------------------------------------------------------------------------------------------------- |
| `nixos-25-11-loaded` | NixOS 25.11 + modern shell and dev tools |
| `nixos-25-11-openclaw` | NixOS 25.11 + OpenClaw |
| `nixos-25-11-hermes` | NixOS 25.11 + Hermes |
| `nixos-25-11-nvidia` | NixOS 25.11 + NVIDIA drivers, CUDA, and GPU containers (`docker --gpus all`). GPU sizes only — see note below. |
| `nixos-25-11` | NixOS 25.11 (minimal) |
| `ubuntu-24-04-loaded` | Ubuntu 24.04 + modern shell and dev tools. **Default.** |
| `ubuntu-24-04-openclaw` | Ubuntu 24.04 + OpenClaw |
| `ubuntu-24-04-hermes` | Ubuntu 24.04 + Hermes |
| `ubuntu-24-04` | Ubuntu 24.04 LTS (minimal) |
NixOS images are built with [Nix Flakes](https://github.com/fdmtl/machine0-nixos) and Ubuntu images with [Ansible Playbooks](https://github.com/fdmtl/machine0-ubuntu)
GPU sizes auto-select the appropriate GPU base image (`gpu-h100x1-base`, `gpu-h100x8-base`, or `gpu-amd-base`). The GPU base images only work with GPU sizes.
For NixOS on GPUs, pass `--image nixos-25-11-nvidia` explicitly — GPU sizes still auto-select the Ubuntu-based `gpu-*-base` images by default. The image ships the NVIDIA driver stack, CUDA, and the container toolkit pre-installed (`docker --gpus all` works out of the box), and the SSH user is `nix`. It runs on the supported NVIDIA GPU sizes: `gpu-4000ada-1`, `gpu-6000ada-1`, and `gpu-h100-1`. AMD sizes (`gpu-mi300x-*`) are not supported. GPU sizes are region-limited — see [Pricing](/introduction/pricing). Like the other GPU base images, it is hidden from `machine0 images ls` by default — use `machine0 images ls --all`. Snapshots you take of it behave like other GPU snapshots (next paragraph): they stay GPU-compatible and can be parked on a CPU size with enough disk, but the NVIDIA stack boots degraded off GPU hardware, so treat CPU sizes as parking rather than a place to run the workload.
Snapshots you take of a GPU VM are regular images with the GPU drivers baked in — you can use them with **any** size that has enough disk (a 1x-GPU snapshot needs `5xl` or `6xl`), and snapshots of those VMs stay GPU-compatible, so you can move the work back to a GPU size later. This makes it cheap to park GPU work: snapshot the GPU VM, destroy it, and pay only for snapshot storage until you need it again.
GPU and standard VMs live in different datacenters within the same region. If a snapshot isn't yet in the datacenter your chosen size needs, `machine0 new` starts the transfer automatically and asks you to retry — it usually takes a few minutes (check progress with `machine0 images get `).
## Custom images
Snapshot any VM into a reusable image:
```bash theme={"theme":"css-variables"}
machine0 images new my-vm my-image
machine0 new clone --image my-image
```
Set a custom image as default:
```bash theme={"theme":"css-variables"}
machine0 config set DEFAULT_VM_IMAGE=my-image
```
## Versioning
Images support multiple versions. Snapshot the same image name again to create a new version. Promote any version to be the active one. See [CLI reference](/cli/images) and [MCP reference](/mcp/images).
## Environment variables and snapshots
Environment variables injected via `--profile` ([profile variables](/cli/env)) are written to disk files (`/etc/environment` and `/etc/profile.d/machine0-env.sh`). When you snapshot a VM with `images new`, these files are captured in the image. Any secrets stored in profile variables will persist in the resulting snapshot. Rotate secrets after saving an image if they should not be reused. This includes the auto-injected [`MACHINE0_API_KEY`](/platform/profiles#environment-variables): VMs created from the image without a profile scrub the env files on first boot, but the key bytes remain inside the image itself (same as `~/.machine0/auth-token` below).
The same applies to credentials injected by `--profile`: `~/.config/gh/hosts.yml`, `~/.codex/auth.json`, `~/.codex/config.toml`, `~/.claude/.credentials.json`, `~/.claude/settings.json`, `~/.claude.json`, and `~/.machine0/auth-token` are on-disk files and travel with snapshots. A codex account credential in particular self-refreshes, so an image baked from a codex-authenticated VM stays signed in on every VM created from it — log out of codex on the VM before snapshotting if that's not what you want. Integrations connected with an **API key** bake that key into the snapshot too, and the key stays valid until you revoke it in the provider's console — treat images made from API-key-authenticated VMs as carrying the key.
## SSH client initial command and snapshots
If the source VM has an [SSH client initial command](/cli/machines#update) set, it is copied onto the snapshot and inherited by VMs created from that snapshot (override it any time with `machine0 update`). Clearing the command on a machine does not remove it from snapshots taken earlier, and pre-existing snapshots are not retroactively updated. The value is stored and displayed in plain text — don't embed secrets in it; use profile variables for secrets. System images never carry an initial command.
## Billing
\$0.078/GB/month based on disk size, billed hourly at the actual prorated cost (no minimum). See [Pricing](/introduction/pricing).
# Networking
Source: https://docs.machine0.io/platform/networking
## Public IP
Every VM gets a dedicated public IPv4. Shown in `machine0 get` and `machine0 ls`. Suspended VMs get a new IP on resume.
## HTTPS proxy
Every VM gets authenticated HTTPS at `https://.mac0.io`, proxying to port 80. No DNS or TLS setup. Renaming a VM updates the endpoint.
## Firewall
All VMs run `ufw` with ports 22, 80, and 443 open. To open more:
```bash theme={"theme":"css-variables"}
machine0 ssh my-vm "sudo ufw allow 8080/tcp"
```
# Profiles
Source: https://docs.machine0.io/platform/profiles
## Overview
A profile is a named set of credentials, MCP connections, prompts, and env variables that you can inject into a VM to give it specific capabilities or a personality.
You can maintain as many as you'd like. For example, a `production` profile might be connected via MCP to your error monitoring and log aggregation tools, and carry a prompt template that resolves the top issues:
```bash theme={"theme":"css-variables"}
machine0 profiles new production --description "Production debugger"
machine0 profiles use production # make it the current profile
machine0 integrations connect claude-code # pre-authenticate claude-code
machine0 integrations connect github # gh + git work on the VM
machine0 integrations add sentry --url https://mcp.sentry.dev/mcp # add the sentry MCP
machine0 prompts add top-sentry --body "go through the top issues on sentry and ..."
machine0 new my-vm --profile production
```
The VM comes up ready: `gh` and `git` are authenticated, `claude` is logged in, and the profile's MCP endpoint is preconfigured in Claude Code and Codex (see [MCP gateway](#mcp-gateway) to configure other clients). `profiles deploy` applies a profile to an already-running VM the same way.
For `claude-code`, the VM receives whichever credential kind you connected: the Anthropic Subscription option is injected as the account login (`~/.claude/.credentials.json`), while the Anthropic API Key option is injected as an API key in `~/.claude.json` (`primaryApiKey`), exactly the way `claude login` records each on your own machine.
Every account starts with a profile named `default`, so you can connect integrations and set variables without creating one first. You always have at least one profile.
The `integrations`, `prompts`, and `env` commands target your **current profile**: `default` out of the box, or whatever you set with `machine0 profiles use `. Target another profile for a single command with `-p/--profile`, or pin one per project by putting `DEFAULT_PROFILE=` in a `machine0.env` file in that directory. `machine0 profiles get` shows which profile is current and where the setting comes from.
## Profile objects
### Integrations
Integrations connect a profile to external services and store the resulting credentials encrypted. There are two types:
* **System integrations** (`claude-code`, `codex`, `github`, `machine0-cli`) hold provider credentials that are injected into VMs: connect once, and every VM created with the profile is pre-authenticated. `claude-code` and `codex` accept either your own API key or an account-based OAuth login — for `claude-code` the choices are **Anthropic Subscription** (a Claude Pro/Max/Team login) and **Anthropic API Key** (the right choice for Console/API-billing accounts); `codex` defaults to the API key. See [integrations connect](/cli/integrations#integrations-connect).
* **MCP integrations** are remote MCP servers you add by URL; their tools are served through the profile's [MCP gateway](#mcp-gateway) (and to VMs created with the profile). You can add up to 50 per profile.
Because integrations live inside profiles, the same service can be connected several times with different accounts. For example, `github` with access to different repos on different profiles.
```bash theme={"theme":"css-variables"}
machine0 integrations ls -p production
┌───────────────────────────────────────────────────────────────────────────┐
│ Name Status Type Description │
│ claude-code connected system claude-code authentication │
│ codex connected system codex authentication │
│ github connected system gh cli and git commands │
│ machine0-cli connected system machine0 CLI │
│ linear-mcp connected mcp https://mcp.linear.app/mcp │
│ sentry connected mcp https://mcp.sentry.dev/mcp │
└───────────────────────────────────────────────────────────────────────────┘
```
Injected credentials are plain files on the VM and travel with [snapshots](/platform/images). When a VM is created from an image without a profile, cloud-init wipes the stale profile files. Created with a profile, each connected integration's file is replaced (including switching auth mode), but a baked credential for an integration the new profile doesn't have stays in place — and the credentials always sit inside the image itself, so rotate or disconnect them before sharing one.
### Prompts
Each profile carries a prompt library, served through its MCP gateway. Prompts appear as slash commands in connected Claude clients.
```bash theme={"theme":"css-variables"}
machine0 prompts ls -p production
┌─────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────┐
│ Name Description Body │
│ inventory -- give me a table of all the mcp tools provided by the machine0 MCP, add title, arguments, short description │
│ top-sentry -- give me a list of the top 3 sentry issues today │
└─────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────┘
```
### Environment variables
Environment variables injected into every VM created with the profile. Use `--secret` for write-only values.
```bash theme={"theme":"css-variables"}
machine0 env set DEV_MODE=true -p production
machine0 env set POSTGRES_URL=... --secret -p production
```
Alongside your own variables, every VM whose profile has `machine0-cli` connected (automatic on create and deploy) also exports two machine0-provided variables:
* `MACHINE0_MCP_URL` — the profile's own [MCP gateway](#mcp-gateway) endpoint
* `MACHINE0_API_KEY` — an API key that authenticates against it. Note this is the same account-level API key the injected machine0 CLI uses — it works against any of your profiles' endpoints and the machine0 API itself, so treat processes you run on the VM accordingly.
Use them to point any third-party tool at the profile's MCP gateway without hardcoding the URL or minting a separate key — for example an MCP client config that takes a `url` plus an `x-api-key` header. If you set either name yourself with `machine0 env set`, machine0 injects neither and your values win — this affects only these two env vars; the key is still injected into `~/.machine0/auth-token` and any connected agent configs. Like all injected credentials, the values refresh on `profiles deploy` or resume — they are not updated live on a running VM, and the same applies after rotating the key (`machine0 integrations connect machine0-cli`): redeploy or resume each profiled VM to pick up the new one.
Like your own [secret variables](/cli/env#env-set), the injected values live in the VM's standard env files (on Ubuntu, `/etc/environment` and `/etc/profile.d/` are readable by every user on the VM) — machine0 VMs are single-user machines, but factor this in before running untrusted multi-user workloads on a profiled VM.
These land in the same places as your own variables: login shells and SSH sessions see them automatically. Systemd units don't read those files — point service definitions at `EnvironmentFile=/etc/environment` (Ubuntu) or `EnvironmentFile=/home//.ssh/environment` (NixOS; that file is plain `KEY=value` lines).
## MCP gateway
Each profile aggregates its MCP integrations and prompts behind a single endpoint:
```
https://app.machine0.io/profiles//mcp
```
You can use it independently of machine0 VMs with any MCP-compatible client. It supports both OAuth and API key authentication (via the `x-api-key` header). The gateway also gives you control over what upstream servers expose:
* **Prefixing**: newly added integrations expose every tool and prompt prefixed with their integration name — an integration named `sentry` serves `sentry_` — so each server's tools are namespaced. `integrations update sentry --prefix s_ -p production` changes it; `--prefix ""` removes prefixing. Integrations added before this default are unchanged: any prefix you set still applies, and unprefixed ones keep serving the server's original names until you set a prefix.
* **Tool whitelist**: `--tool-whitelist list,get` serves only the tools whose names start with one of the entries. Entries match the server's original names, before any prefix is applied.
## Commands
See the CLI reference: [`profiles`](/cli/profiles), [`integrations`](/cli/integrations), [`env`](/cli/env), [`prompts`](/cli/prompts).
# Provisioning
Source: https://docs.machine0.io/platform/provisioning
Provisioning configures a VM after creation. NixOS VMs use Nix flakes. Ubuntu VMs use Ansible.
## Nix flakes
```bash theme={"theme":"css-variables"}
machine0 provision my-vm ./flake.nix#profile
machine0 provision my-vm ./my-flake-dir#default
machine0 provision my-vm github:owner/repo#devbox
```
NixOS images are built with [Nix Flakes](https://github.com/fdmtl/machine0-nixos)
## Ansible
```bash theme={"theme":"css-variables"}
machine0 provision my-vm playbook.yml
```
The default Ubuntu image is built with Ansible. See the [machine0 Ansible playbook](https://github.com/fdmtl/machine0-ansible).
## Details
See [CLI reference](/cli/machines#provision) for full flag documentation.
# Security
Source: https://docs.machine0.io/platform/security
## Access
* SSH-only. Password authentication disabled.
* Root login disabled. Access via `ubuntu` (or `nix` on NixOS) with sudo.
* Cloud-init randomizes the root password on every VM.
## Keys
**Public keys** -- your private key never leaves your machine.
**Managed keys** -- server-generated keypair. Private key returned once at creation, saved locally with `0600` permissions.
## Network
* Every VM gets a dedicated public IP.
* VMs are isolated from each other at the network level.
* HTTPS endpoints at `.mac0.io` are authenticated to the VM owner.
* `ufw` enabled by default with ports 22, 80, 443 open.
# SSH
Source: https://docs.machine0.io/platform/ssh
## Default behavior
On first VM creation, the CLI registers your `~/.ssh/id_rsa.pub` and sets it as default. Your private key never leaves your machine.
## Key types
**Public keys** (bring your own) -- machine0 stores only the public half.
**Managed keys** (server-generated) -- the server creates the keypair and returns the private key once. Saved locally with `0600` permissions. Required for MCP [ssh\_exec](/mcp/ssh).
Managed private keys can only be downloaded once at creation time.
## SSH users
| Image | Default user |
| ------------------- | ------------ |
| Ubuntu | `ubuntu` |
| NixOS (provisioned) | `nix` |
Root login is disabled. Both users have full sudo.
## In-browser terminal
For VMs created with a **managed key**, the web dashboard offers an in-browser
terminal. Click SSH on any running VM in the dashboard and a full-screen shell
opens at `/machines//terminal`. The browser connects over WebSocket; the
server uses the managed private key to bridge to the VM's `sshd`. No local
SSH setup needed.
VMs created with a user-provided public key (the default) cannot use the
in-browser terminal — the server does not have the private key. Use
`machine0 ssh ` from your local terminal instead.
Sessions stay connected through long-running commands (the server sends a
4-minute keepalive frame) and auto-close after 30 minutes of inactivity.
Destroying the managed key via `machine0 ssh-keys destroy` or the dashboard
terminates any active terminal sessions using that key.
## Commands
See [CLI reference](/cli/keys) for key management commands.

## Lifecycle states
| State | Billed? | Has IP? | Notes |
| ------------- | ----------------------------- | ------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `CREATING` | No | No | Provisioning (1-3 min, longer for large images). Billing starts once it's running. |
| `RUNNING` | Yes | Yes | Ready for SSH |
| `STOPPED` | Yes | Yes | Resources reserved. Still billed at full rate. |
| `SUSPENDING` | -- | -- | Snapshotting in progress |
| `SUSPENDED` | Image storage only | No | Cloud instance deleted. \~\$0.078/GB/mo. |
| `UNAVAILABLE` | No (snapshot storage, if any) | No | Couldn't start or resume (provider out of capacity). No running VM, so no machine billing; a retained snapshot bills storage. Recovers automatically (see below); `machine0 start` retries immediately. |
| Destroyed | No | -- | Gone. Irreversible. |
### Out-of-capacity (`UNAVAILABLE`)
When the cloud provider has no capacity for a VM's size (mostly GPU sizes), the create or resume lands in `UNAVAILABLE`. `machine0 get` explains what happened, and recovery is automatic:
* **A resume that failed** returns to `SUSPENDED` within about ten minutes. Your data is safe in the suspend snapshot the whole time.
* **A brand-new VM that never started** is removed automatically about 30 minutes after the failure.
`machine0 start ` retries right away in either case — it fails fast with a clear error if the size is still out of stock.
Stopped VMs bill at full rate because cloud resources stay reserved. Suspend or destroy to stop machine billing.
## Suspend vs stop vs destroy
**Stop** keeps the cloud instance alive. Resources stay reserved, billing continues, IP is retained. Use when you need the VM back quickly with the same IP.
**Suspend** snapshots the VM, deletes the cloud instance, and stops machine billing. You pay only image storage (\~\$1.95/mo for a 25 GB boot disk). [Disks](/platform/disks) attached to the VM keep billing while it is suspended and are re-attached on resume. Resume later with `machine0 start` -- the VM gets a new IP. The snapshot (named `suspended---`) is the suspended VM's only copy of its disk: deleting it with `machine0 images rm` also destroys the suspended machine.
**Destroy** deletes everything permanently.
## HTTPS proxy
Every VM gets authenticated HTTPS at `https://.mac0.io`, proxying to port 80. No DNS or TLS setup needed. Renaming a VM updates the endpoint.
## In-browser terminal
VMs created with a managed key get a one-click in-browser shell from the web
dashboard. See [SSH → In-browser terminal](/platform/ssh#in-browser-terminal).
## Commands
See [CLI reference](/cli/machines) and [MCP reference](/mcp/machines).
