🚀 Operative.sh WebEvalAgent MCP Server
Let the code fix itself, you’ve got better things to do.
🔥 Supercharge Your Debugging
operative.sh’s MCP Server unleashes LLM-powered agents to autonomously execute and debug web apps directly in your code editor.
⚡ Features
This weapon in your development arsenal transforms your Code IDE experience (Cline, Cursor):
- 🌐 Navigate your webapp using BrowserUse (now 2x FASTER when using our backend!)
- 📊 Capture network traffic - all requests/responses at your fingertips
- 🚨 Collect console errors - nothing escapes detection
- 🤖 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)
- Run the installer after getting an api key (free)

# curl -LSf https://operative.sh/install.sh | less -N
# Download, install, and remove the installer script
curl -LSf https://operative.sh/install.sh -o install.sh && bash install.sh && rm install.sh
