Chrome DevTools MCP is an npm package that acts as a Model-Context-Protocol server, enabling AI coding agents like Gemini, Claude, Cursor, and Copilot to control and inspect a live Chrome browser.

It provides Chrome DevTools capabilities for performance tracing, network analysis, console debugging, screenshots, and Puppeteer-based automation. Installation uses npx with MCP client configs; requires Node.js v20.19+, current Chrome, and npm; includes opt-outs for usage stats and CrUX data.
