operative.sh's MCP Server is a tool for autonomous debugging of web applications directly from your code editor.

The operative.sh web-eval-agent MCP Server is designed to enhance the debugging process by allowing a browser-use powered agent to autonomously execute and debug web applications directly within your code editor. This server is part of the operative.sh suite and is aimed at developers who want to streamline their debugging workflow. It provides features such as navigating web applications, capturing network traffic, collecting console errors, and performing autonomous debugging. The server uses tools like the web_eval_agent to evaluate user experience and setup_browser_state to manage browser sessions. It integrates with various platforms and can be installed manually or through a quick start script.

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 expected end-to-end

Tools

  • 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.
