🚀 operative.sh web-eval-agent MCP Server

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

🔥 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.

🧰 MCP Tool Reference

| Tool | Purpose | |------|---------| | web_eval_agent | 🤖 Automated UX evaluator that drives the browser, captures screenshots, console & network logs, and returns a rich UX report. | | setup_browser_state | 🔒 Opens an interactive (non-headless) browser so you can sign in once; the saved cookies/local-storage are reused by subsequent web_eval_agent runs. |

Key arguments

• web_eval_agent

  • url (required) – address of the running app (e.g. http://localhost:3000)
  • task (required) – natural-language description of what to test ("run through the signup flow and note any UX issues")
  • headless_browser (optional, default false) – set to true to hide the browser window

• setup_browser_state

  • url (optional) – page to open first (handy to land directly on a login screen)

You can trigger these tools straight from your IDE chat, for example:

Evaluate my app at http://localhost:3000 – run web_eval_agent with the task "Try the full signup flow and report UX issues".
