Agent Comm Overview

The agent-comm MCP server connects AI coding agents through direct messages, channels, shared state, and presence tracking. It runs as a Node.js stdio MCP server backed by SQLite, with REST and WebSocket interfaces for hooks, dashboards, and custom clients. Agents can register, discover peers, exchange threaded or broadcast messages, poll for incoming work, and coordinate shared values with atomic compare-and-set operations. Reach for it when multiple agents work on the same codebase and need a common coordination layer.

Primary Use Cases for Agent Comm:
  • Register agents by capability for task routing
  • Send threaded messages between coding agents
  • Coordinate work through shared key-value state
  • Manage channels for project-specific discussions
