🚀 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".

🏁 Quick Start

Easy Setup with One-Click Integration

1. Get your API key (free) - when you create your API key, you'll see:
   • "Add to Cursor" button with a deeplink for instant Cursor installation
   • Prefilled Claude Code command with your API key automatically included

Manual Setup (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

2. Run the installer after getting an api key (free)
   • Installs playwright
   • Installs uv
   • Inserts JSON into your code editor (Cursor/Cline/Windsurf) for you!

curl -LSf https://operative.sh/install.sh -o install.sh && bash install.sh && rm install.sh

3. Visit your favorite IDE and restart to apply the changes
4. Send a prompt in chat mode to call the web eval agent tool! e.g.

Test my app on http://localhost:3000. Use web-eval-agent.
