MCP.Pizza Chef: refreshdotdev

The project has been sunset by its makers and is no longer maintained, so treat it as a snapshot rather than a living tool. While it ran, it drove a real browser through a site you were building, attempting a task you described in plain words, then handed back a report of the steps taken, the error messages it saw, and the rough spots in the experience. It worked inside Cursor, Cline, and Windsurf, and needed a free key from operative.sh.

🔥 Supercharge Your Debugging

operative.sh's MCP Server launches a browser-use powered agent to autonomously execute and debug web apps directly in your code editor.

⚡ Features

  • 🌐 Navigate your webapp using BrowserUse (2x faster with operative backend)
  • 📊 Capture network traffic - requests are intelligently filtered and returned into the context window
  • 🚨 Collect console errors - captures logs & errors
  • 🤖 Autonomous debugging - the Cursor agent calls the web QA agent mcp server to test if the code it wrote works as epected end-to-end.
