Sessions register a name, send each other messages, join teams. It&rsquo;s genuinely useful, the agent working on the MicroPython unix port can ask the agent working on the picolet runtime what branch it&rsquo;s actually building, and get an answer, without me being the messenger.</p> <p>Every session runs a plugin to talk to that hub. The plugin is an MCP server: a child process Claude Code spawns, speaking JSON-RPC over stdio on one side and a <code>wss://</code> websocket to the hub on the other. One per session. Written in TypeScript, run under Bun.</p>
