Agent Comm

Agent Comm is an open-source MCP (Model Context Protocol) server designed to facilitate real-time intercommunication, state sharing, and coordination between multiple AI coding agents, such as Claude Code, Cursor, Codex CLI, and any custom MCP-compatible AI tools. It exposes REST, WebSocket, and MCP stdio endpoints, enabling agents to register/discover each other, exchange messages (direct, broadcast, and channel-based), share and atomically update state (key-value store), log and observe activity events, and serialize access to shared resources and files. Built with hooks for robust file coordination and process guarding, Agent Comm ensures agents avoid conflicts and can coordinate complex coding or automation workflows across parallel AI agents or terminals, making it ideal for developer teams, researchers, and engineering organizations experimenting with multi-agent systems.
