🚀 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.

🏁 Quick Start (macOS/Linux)

  1. Pre-requisites (typically not needed):
  • brew: /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
  • npm: (brew install npm)
  • jq: brew install jq
  1. Run the installer after getting an api key (free)
