# Sendmux CLI

## ClawHub account note

This ClawHub skill connects OpenClaw agents to Sendmux. Some workflows require a Sendmux account and an appropriate Sendmux API key or agent token. Sendmux account usage is external to ClawHub; do not ask users to paste secrets into chat.

Use this skill when the terminal is the right Sendmux surface.

## Boundaries

- Do not ask the user to paste API keys.
- For API-key profiles, use `smx_root_` for `management:*` and `smx_mbx_` or scoped `smx_agent_` for `mailbox:*`.
- OAuth profiles require the operation's approved surface, scopes and mailbox access. REST OAuth tokens authenticate HTTP, not SMTP or IMAP.
- Durable agent profiles can read and receive mail while active, but cannot send until an invited owner accepts and approves sending.
- After owner approval, `sending:*` commands with an agent profile automatically exchange and cache a one-hour delegated token.
- Do not run destructive commands without explicit confirmation.
- Use `--json` for agent-readable output.
- Prefer task-specific Sendmux skills when the user needs strategy; use this skill for exact CLI mechanics.

## Install

```bash
npm install -g @sendmux/cli
sendmux --help
```

The package exposes the `sendmux` binary.

## OAuth login and connection checks

For an existing user's account, create a new named OAuth profile with the required scopes:

```bash
sendmux auth:login work --scope mailbox.read --scope email.send
sendmux mailbox:get-connection --profile work --json
```

The CLI opens browser consent and receives the callback on the same computer. `--no-browser` only suppresses automatic browser launch an

## Description:

Use the Sendmux CLI for durable agent inbox registration, owner invites, profiles, and terminal-driven Management, Mailbox, and Sending workflows.

This skill is ready for commercial/non-commercial use.

## Publisher:

[sendmux.ai](https://clawhub.ai/user/sendmux.ai)

### License/Terms of Use:

MIT-0

## Use Case:

Developers and agent operators use this skill to set up Sendmux inboxes and profiles, check access, and carry out email, mailbox, and account-management tasks from a terminal.

### Deployment Geography for Use:

Global

## Known Risks and Mitigations:

Risk: Credentials for mailbox, sending, or account management could be exposed or granted excessive access.

Mitigation: Keep keys in a secret store or environment and use scoped profiles or OAuth where possible; do not paste secrets into chat or command arguments.

Risk: Sending mail or changing account settings can have unintended effects.

Mitigation: Review send and account-management commands before execution and confirm destructive actions explicitly.

Risk: Saved profiles can retain access after the task ends.

Mitigation: Log out or revoke profiles when access is no longer needed.
