Command Mail plugin
Command Mail is one inbox for all of your email addresses, built so your AI agent can work in it. The agent reads, searches, sorts and drafts, and sends only if you allow it, per permission and per mailbox.
This repository connects agent hosts to the hosted Command Mail MCP server at https://commandmail.app/mcp and adds a mail workflow skill. You need a Command Mail account: start for free with one address; Pro adds sending, more addresses and your full history.
The server is also listed in the Official MCP Registry as app.commandmail/mail.
Install
ChatGPT and Codex. Command Mail will appear in the ChatGPT and Codex plugin directory once it is listed there. Until then, add this repository as a marketplace in Codex:
codex plugin marketplace add FYN-Labs/commandmail-plugin
codex plugin add command-mail@commandmailClaude Code.
/plugin marketplace add FYN-Labs/commandmail-plugin
/plugin install command-mail@commandmailCursor. Clone the repository into your local plugin folder, then run Developer: Reload Window:
git clone https://github.com/FYN-Labs/commandmail-plugin ~/.cursor/plugins/local/command-mailGemini CLI.
gemini extensions install https://github.com/FYN-Labs/commandmail-pluginAny other MCP client. Add a remote MCP server with the Streamable HTTP transport and the URL https://commandmail.app/mcp.
Sign in
On first use, your agent opens Command Mail in the browser. Sign in and switch on the permissions you want to grant; sending without your approval starts switched off. The connection uses OAuth 2.1 with PKCE, so you never give the agent a password or API key. You can disconnect an agent at any time under Settings → Connections.
Permissions
Each mailbox also has an autonomy level (read, suggest, rules or auto) that limits what an agent may change. Email content is treated as data, never as instructions.
Network and credentials
The plugin ships no executable code, hooks or install scripts. It declares one remote MCP server, https://commandmail.app/mcp, and the agent host talks only to commandmail.app: the MCP endpoint and the OAuth endpoints it advertises under /.well-known/. The only credential is the OAuth token your agent host receives after you sign in; you never enter a password or API key into the plugin.
Package layout
plugin.json also carries the listing, review cases and release notes for the OpenAI plugin directory under extensions.com.openai. Build the upload ZIP with scripts/build-openai-zip.sh /path/to/commandmail-plugin.zip; it contains only the portable package. Reviewer credentials never belong in this repository.
