Chrome DevTools for agents

Chrome DevTools for agents (formerly Chrome DevTools MCP, npm package chrome-devtools-mcp) is an MCP server from the Chrome DevTools team. It lets a coding agent such as Antigravity, Claude, Cursor, Copilot, Codex or Gemini CLI control and inspect a live Chrome browser. A CLI is also provided for use without MCP.

The agent can record performance traces, analyze network requests, read console messages with source-mapped stack traces, take screenshots, fill forms, click, emulate devices and locations, and run Lighthouse audits. It uses Puppeteer for automation. It can start its own Chrome or connect to a Chrome session you already have open.

It runs locally with Node.js (LTS), npm and current stable Chrome. It is free and open source under the Apache-2.0 licence. Google collects usage statistics by default; the --no-usage-statistics flag turns this off.

Creat pentru

Developers who use AI coding agents to build websites and want the agent to test, debug and verify its code in a real Chrome browser. Also for makers of agent tools who want to add a browser subagent.

Cazuri de utilizare

• Verify in the browser that a code change works

• Playwright MCP

  Records performance traces and runs Lighthouse audits with source-mapped console messages from Chrome DevTools; it also ships a CLI for use without MCP.

• Cloudflare MCP Server

  Runs on your own computer and can connect to the Chrome session you already have open; Cloudflare's Browser Run server is hosted and needs a Cloudflare account.

• Sentry MCP

  Free under Apache 2.0 and needs no account: it inspects the live page while you develop, before any error reaches a monitoring service.
