chrome devtools mcp — Agent Skill

Chrome DevTools for agents

Chrome DevTools for agents (chrome-devtools-mcp) lets your coding agent (such as Antigravity, Claude, Cursor or Copilot) control and inspect a live Chrome browser. It is available as a Model-Context-Protocol (MCP) server and as a [CLI][cli]. Both give your AI coding assistant access to the full power of Chrome DevTools for reliable automation, in-depth debugging, and performance analysis.

Key features

• Get performance insights: Uses [Chrome

DevTools](https://github.com/ChromeDevTools/devtools-frontend) to record traces and extract actionable performance insights.

• Advanced browser debugging: Analyze network requests, take screenshots and

check browser console messages (with source-mapped stack traces).

• Reliable automation. Uses

puppeteer to automate actions in Chrome and automatically wait for action results.

Disclaimers

chrome-devtools-mcp exposes content of the browser instance to the MCP clients allowing them to inspect, debug, and modify any data in the browser or DevTools. Avoid sharing sensitive or personal information that you don't want to share with MCP clients.

chrome-devtools-mcp officially supports Google Chrome and Chrome for Testing only. Other Chromium-based browsers may work, but this is not guaranteed, and you may encounter unexpected behavior. Use at your own discretion. We are committed to providing fixes and support for the latest version of Extended Stable Chrome.

Performance tools may send trace URLs to the Google CrUX API to fetch real-user experience data. This helps provide a holistic performance picture by presenting field data alongside lab data. This data is collected by the Chrome User Experience Report (CrUX). To disable this, run with the --no-performance-crux flag.
