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.
Managed private keys can only be downloaded once at creation time.
