From the repository
Run the script rpc-proxy-worker.js with Node.js (no additional install steps besides having Node.js). The server starts on port 3005 by default, serving a web dashboard at http://localhost:3005. Clients interact via HTTP endpoints (e.g., GET /tool/:toolName, POST /rpc/raw/command) or by connecting to the SSE endpoint at /sse.
