An MCP server that lets one coding agent talk to another: Claude Code, Codex or Grok. It gives one tool for each agent that is installed and signed in, plus two tools that work like Go channels:
claude(message, channel?), codex(…), grok(…) send a message and return a channel id at
once. Without channel, the message starts a new session. With channel, it is a follow-up.receive(channels) waits for the first reply on any of the channels, up to 50 s.close(channel) stops the agent and ends the channel.Each channel is one agent session. Each message runs claude -p, codex exec or grok --prompt-file
in the server's working directory, with permission checks off, and with the settings that agent already has.
Linux and macOS, prebuilt:
From source:
The server offers every agent that is installed and signed in when it starts.
The called agent runs with permission checks off. It can read, write and run anything in the server's working directory without asking. Any agent that can call agentchan gets that access.
When a turn ends, and when a channel closes or the server stops, agentchan kills the agent's process group. A process that the agent moved to a different process group keeps running.
Each message uses the called agent's own login and plan limits. Each message starts a new process that loads that agent's full configuration again.
