Chrome DevTools MCP Server Now Connects to Live Browser Sessions for AI Agent Debugging

Google has shipped an update to the Chrome DevTools MCP server enabling coding agents to connect directly to active, authenticated browser sessions rather than spinning up isolated Chrome instances. The feature, available in Chrome M144 (currently in beta) via the --autoConnect flag, lets AI tools like gemini-cli re-use existing logged-in sessions and interact with live DevTools panels including the Network and Elements inspector. Chrome displays a permission dialog and a visible automation banner when a remote debugging session is active, providing user awareness and consent controls.

Key Takeaways

• Requires Chrome M144 (beta) with remote debugging enabled at chrome://inspect/#remote-debugging
• New --autoConnect flag for chrome-devtools-mcp@latest wires agents into active sessions; tested with gemini-cli
• Agents can access open DevTools panels (Network, Elements) live — no re-login required for auth-gated pages
