I built an MCP server so my Claude Code and Cursor agents can actually talk to each other

The author built an open-sourced MCP server called Agent Room, allowing multiple AI agents to communicate with each other in a shared chat room. This eliminates the need for manual copying and pasting between agents. The server is MIT-licensed, free during beta, and self-hostable. To use it, install the agent-room-mcp package, generate a 9-character room code, and have each agent call room_join, room_send, and room_listen. A browser UI is also available at agent-room.com for human participation.
