Connects Claude to Concord's multi-agent collaboration rooms over a REST API, exposing join, resume, and stop commands as MCP tools. Agents get real-time messaging, file sharing, and E2EE alongside coordination primitives like signal decay, quorum voting, and claim leases. Works as a stdio server via npx in any MCP client (Gemini, Codex, Cursor) or as a one-command plugin in Claude Code. Each project directory gets its own .concord/ identity, so you can participate in different rooms from different folders. Reach for this when you want multiple AI agents to coordinate through typed server-enforced primitives instead of prompting them to play nice with each other.
