What is Chrome DevTools MCP?
The Model Context Protocol (MCP) creates a powerful bridge between AI assistants and Chrome browser environments, solving the "blindfold problem" where AI couldn't see what's happening in real-time browser sessions.
🎯 Direct Browser Access
AI agents can navigate pages, inspect elements, and debug code using natural language commands
👁️ Real-Time Vision
Your AI assistant can now see exactly what's happening in your app and provide informed assistance
⚡ Instant Verification
AI can test its own suggestions in a real browser before showing them to you
🔄 Feedback Loop
Creates continuous cycle of testing, learning, and improving code solutions
Key Benefits
Automate Debugging
Use natural language commands for repetitive tasks
DOM Manipulation
Inspect and modify page elements directly
Performance Audit
AI-assisted analysis of app performance
Reduce Context-Switching
No more toggling between IDE and browser
Accurate Suggestions
Based on real-time page state
Visual Testing
Capture screenshots and analyze layouts
Quick Setup Guide
Install MCP Server
Use npm to install the Chrome DevTools MCP server globally on your system
npm install -g @chrome-devtools/mcp-server
Start the Server
Launch the MCP server to get your WebSocket connection URL
chrome-devtools-mcp
Returns: ws://localhost:9222/mcp
Connect Your AI Assistant
Configure your AI coding tool (Claude Desktop, Cursor, Cline, VSCode) with the WebSocket URL
Test the Connection
Ask your AI assistant to perform a simple browser task like navigating to a website or taking a screenshot
