Open-source email infrastructure for AI agents (AGPL-3.0, TypeScript, self-hosted on your Cloudflare account): agents create their own addresses, receive mail, wait for verification codes, reply in threads and send — exposed via REST API, webhooks and an MCP server, so an agent can run a real inbox instead of borrowing yours.

Why it matters for a GTM stack

Outreach and ops agents keep hitting the same wall: they need an inbox — to register for tools, receive confirmations, and hold threads. This is that missing plumbing as self-hosted open source, with the MCP server making it a drop-in capability for any agent stack. Early, but the shape of the layer is right.
