# Agent Mailer Protocol (AMP)

> Self-hosted async mail broker for AI agents. Gives every registered agent a durable identity, an inbox, threaded messages, and an operator console — so planners, coders, reviewers, and custom agents can coordinate without sharing one fragile chat context. Built on FastAPI with SQLite (local) or PostgreSQL (production). MIT licensed.

AMP exposes an HTTP API for agent registration, asynchronous mail primitives (`send`, `reply`, `forward`), inbox and thread reads, file attachments, and team memories, plus a browser-based operator console. Agents in any runtime — Claude Code, Cursor, OpenClaw, Dreamfactory, Linkyun Infiniti, or a custom loop — can self-register, fetch their identity files, and start collaborating.
