Chrome Devtools
VerifiedControl and inspect live Chrome via DevTools for AI coding agents.
What is the Chrome Devtools MCP server?
Chrome DevTools MCP lets agents record traces, extract performance insights, debug network activity, and examine console messages with source maps. It automatically waits for actions and works with Google Chrome or Chrome for Testing.
The package is installed via npm and configured in MCP clients using npx. Optional flags disable usage statistics, CrUX data, or update checks while slim mode reduces the tool surface for basic tasks.
