Claude Peers MCP

<p>Claude Peers MCP is an MCP server that lets multiple Claude Code instances find each other and exchange messages in real time. No central orchestrator. No predefined workflows. Just a lightweight broker daemon on localhost:7899 that connects whatever Claude Code sessions you have running.</p> <p>The setup is dead simple: clone the repo, add it to your <code>.mcp.json</code>, and the broker auto-launches when your first session starts. Each Claude Code instance registers as a peer, and from that point, any peer can list all running instances (with their working directory, git repo, and activity summary) and send messages to any other peer.</p> <p>Messages arrive instantly via the <code>claude/channel</code> protocol push. No polling delay for the receiving agent. Dead peers get cleaned up automatically — if a session crashes or closes, it's removed from the registry within seconds.</p> <p>The communication model is ad-hoc. There's no master/worker hierarchy, no task queue, no predefined roles. Agents negotiate freely. A writer agent can ask a reviewer agent to check its work. A frontend agent can query a backend agent about API contracts. A coordinator can delegate tasks to specialists. The protocol doesn't care — it just moves messages.</p> <p>The broker uses SQLite for message persistence and runs entirely on localhost. Nothing leaves your machine. Optional GPT-5.4-nano summaries can describe what each instance is working on, making it easier for agents to find the right peer to talk to.</p> <p>Created by Louis (louislva), Claude Peers MCP was featured in GitHub Open Source Weekly on March 25, 2026, as part of the growing agent coordination trend.</p>
