MCP Agent Mail

Mail-like coordination layer that gives AI coding agents inboxes, threads, and file leases to avoid collisions.

Desktopfreeglobal

MCP Agent Mail is a mail-like coordination layer for AI coding agents, exposed as an HTTP-only FastMCP server, giving each agent a memorable identity, inbox and outbox, searchable message history, and voluntary file-reservation leases so agents working in parallel on the same project don't overwrite each other's edits. It's backed by Git for human-auditable history and SQLite for indexing, aimed at teams running several coding agents on the same codebase at once.
