Operative-Sh/web-eval-agent: An MCP server that autonomously evaluates web applications.

Let the coding agent debug itself, you’ve got better things to do.

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

• 🌐 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.
