Chrome DevTools MCP is an official server that connects AI coding assistants to a live Chrome browser, enabling them to perform real-time debugging, performance analysis, and browser automation.
It acts as a bridge that allows agents to inspect the DOM, analyze network requests, run Lighthouse audits, and interact with web pages as if a human developer were using DevTools.
- 01
Performance tracing and automated Lighthouse-style audits
- 02
Advanced browser debugging including network inspection and console log analysis
- 03
Reliable browser automation for user flows, form filling, and navigation
- 04
Live session attachment via --autoConnect for persistent state and authentication
- 05
Memory heap snapshotting and analysis for leak detection

Best for
Frontend developers and AI agents needing to debug runtime issues, optimize web performance, or verify code changes in a real browser environment.
Not ideal for
Deterministic end-to-end (E2E) testing (use Playwright MCP instead) or debugging non-Chromium browsers like Safari or Firefox.
An essential, high-leverage tool for any developer using AI coding assistants; it eliminates the friction of manual copy-pasting by giving AI direct, actionable visibility into the browser.
As of late 2025 and early 2026, the tool has matured with the addition of the --autoConnect feature (Chrome M144+), allowing agents to attach to existing browser sessions to preserve cookies and login states.
