Your mailbox as MCP tools
A native Model Context Protocol (MCP) server. Point an MCP client at one endpoint and your agent gets email as callable tools.
The MCP endpoint and a mailbox key.
How it works
The server speaks the streamable-HTTP transport. Authentication is a mailbox API key, the same scoped key as the REST API, so a client gets only the role you grant. Connect a client and the mailbox's actions appear as tools.
Connect a client
Point your client at the MCP endpoint and pass a mailbox API key as a Bearer token.
What your agent can do
The mailbox surfaces its actions as tools: messages.send, messages.list, messages.search, threads.reply, and the rest of the mailbox surface. The full tool set is published from the live server in the API reference ↗.
Scoped by design
Each key is scoped to a single mailbox with one role and an optional expiry, so a connected client can do only what you allow. Suppression and limits are isolated per mailbox.
