An asynchronous coordination layer for AI coding agents exposed as an HTTP-only FastMCP server. It enables agents to register persistent identities, send and receive GitHub-flavored Markdown messages, search and thread conversations, and declare advisory file reservation leases to avoid conflicts. The system uses Git for human-auditable artifacts and SQLite for indexing and queries, designed to work with multiple AI coding assistants like Claude Code, Codex, Gemini CLI, and Factory Droid.
