Google's official chrome-devtools-mcp server and CLI are now marked officially stable (v1.1.1), letting coding agents attach to a live Chrome session for reliable automation, in-depth debugging, and performance analysis. New features include WebMCP tool listing/execution from within DevTools, custom third-party debugging tools that pages define via JavaScript, and custom HTTP header emulation (auth tokens, custom User-Agents). The repo is at 43k+ stars.
