Overview
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 acts as a Model-Context-Protocol (MCP) server, giving your AI coding assistant access to the full power of Chrome DevTools for reliable automation, in-depth debugging, and performance analysis. A CLI is also provided for use without MCP. - 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.

}Capabilities
- Performance tracing
Ask your assistant to run `performance_start_trace` and `performance_stop_trace` to record and analyze page load performance insights.
- Network debugging
Use `list_network_requests` and `get_network_request` to inspect API calls, status codes, and response details.
- Console monitoring
Check `list_console_messages` and `get_console_message` for errors, warnings, and source-mapped stack traces.
- Browser automation
Direct your assistant to `click`, `fill`, `navigate_page`, or `take_screenshot` to interact with and capture live pages.
- Memory analysis
Enable memory debugging to `take_heapsnapshot` and `query_heapsnapshot_objects` for finding leaks and retained objects.
- Lighthouse audits
Run `lighthouse_audit` to get performance, accessibility, and SEO scores for any URL.
