Chrome DevTools MCP v1.2.0 Adds --autoConnect: Agents Attach to a Live Browser Session

GitHub·high signal

ChromeDevTools/chrome-devtools-mcp (~43K stars) is Google's official MCP server that gives coding agents real visibility into a live Chrome session — network inspection, console with source-mapped traces, screenshots, and Puppeteer-driven actions. Version 1.2.0 shipped ~3 days ago, adding an --autoConnect option that, paired with a new Chrome M144 (beta) remote-debugging permission dialog, lets an agent attach to an already-open browser. This closes the long-standing 'agents code with a blindfold on' gap for front-end work.
