chrome-devtools-mcp is a Model Context Protocol (MCP) server and command-line tool that lets a coding agent control and inspect a live Chrome browser. The page says it works with agents such as Antigravity, Claude, Cursor and Copilot, and gives them access to Chrome DevTools for browser automation, debugging and performance analysis.

It can record performance traces and extract performance insights, analyse network requests, take screenshots, and check browser console messages with source-mapped stack traces. Browser automation uses Puppeteer, which waits for each action to produce a result before continuing.

It is for developers who use AI coding assistants and want those assistants to test, debug or measure a web page in Chrome. Setup means adding a short entry to the MCP client configuration that runs the package through npx. The browser starts when a client first calls a tool that needs one. A chrome-devtools CLI is also included for terminal use, along with skills that teach agents specific tasks such as accessibility audits, Largest Contentful Paint debugging and memory leak hunting.

The page includes several disclaimers. The server exposes browser content to MCP clients, so users should avoid sharing sensitive information. It officially supports Google Chrome and Chrome for Testing only. Usage statistics are collected by default and can be turned off with a flag, and performance tools can send trace URLs to the Chrome User Experience Report API unless disabled.

The project is open source under the Apache-2.0 license. The page does not list a price for the tool itself.
