This MCP server implementation creates a mailbox system enabling two AI agents to communicate asynchronously through message passing. Built by Tim Kellogg using FastAPI and SQLite, it provides send_to_agent and check_mail tools that allow agents to exchange messages via a persistent database queue. The server supports multi-agent workflows where agents need to coordinate tasks, share information, or hand off work to each other, with each agent accessing their own mailbox through unique HTTP endpoints.
