Overview

Email infrastructure for AI agents: every agent is an identity with its own mailbox, plus shared contacts, notes, and an encrypted vault.

MCPmailer gives an agent a real mailbox at a real address. It can send, receive, thread, search, and wait for a reply the way a person does, over MCP or over plain HTTPS. Around the mailbox sit the things an agent needs to hold a conversation over time: a workspace address book it can write to, shared notes that outlive a session, and a vault of credentials it can use without any of them passing through a prompt.

Everything is scoped to an identity. One handle, one mailbox, one API key, so an agent can only ever send from the address it owns and read the mail addressed to it.

Where to start#

There are two ways in, and neither is the advanced one. If you already run an agent, connect it to a mailbox and you are done: no key, no file, no terminal. If you are writing the agent yourself, point it at the endpoint or call the API directly.
