Chrome DevTools MCP Hits 522pts — Coding Agents Can Now Debug Live Authenticated Browser Sessions
Google shipped an enhancement to Chrome DevTools MCP (requiring Chrome M144, currently in beta) that lets coding agents auto-connect to your running browser session via `--autoConnect`, including sessions behind sign-in walls and active DevTools debugging panels. Agents can inspect network requests you've already selected, elements, and console state — bridging manual and AI-assisted debugging in one workflow. Chrome shows a permission dialog on each connection and a banner while the session is active; the HN community surfaced this December 2025 post today at 522pts/209cmts, signaling major practitioner demand.
