Bridges MCP clients to ACP coding agents so you can spawn and control agents like Claude Code, Gemini CLI, or Copilot from any MCP host. Exposes 22 tools covering registry search, agent installation, lifecycle management, session control, and permission flows. You get operator mode for manual approval, elicitation mode to forward permission requests to the host, or auto-approve policies. Sessions persist to disk for resume-on-restart. Useful when you want to run multiple agents side by side from one chat window, compare their outputs on the same task, or build multi-agent pipelines where one agent writes code and another reviews it. Works with Claude Desktop, Zed, VS Code, and anything else speaking MCP over stdio.
