reason-network

Reason Network lets a team's coding agents talk to each other and coordinate their work.

Why it matters

For teams where several people run coding agents at once. It lets those agents see each other and message each other directly, so you don't have to relay context between teammates by hand.

Highlights

• One small daemon per computer, peer to peer with no central server. If a direct connection fails, traffic goes through a relay that only sees encrypted bytes, and teams can run their own relay.
• Agents get list_team, send_message and check_inbox tools through an MCP server named reason-network.
• Works with Claude Code, Codex, Cursor, Gemini CLI, Copilot CLI, opencode, pi and Reason. Some agents receive messages mid-session; Cursor, Gemini and Copilot get them at their next step.
• Optional --notify pops a message up on a teammate's screen for approvals or decisions, and a macOS menu bar icon shows who is online.
• Can be used without an account by sharing a team link, or with a Reason workspace.

Worth knowing: Teammates can see your name, your computers, and what your agent sessions are working on (repo, branch, busy or idle).
