    Chrome DevTools made an MCP server

    Chrome DevTools released a public preview of their MCP server that enables AI coding agents to control and inspect live Chrome browsers. This tool addresses the limitation of agents coding blindly by providing them with browser inspection capabilities through Puppeteer-powered MCP integration. Agents can now debug applications by inspecting DOM, reading console logs, checking network requests, automating user flows, and running performance audits. The newsletter also covers various web development topics including CSS specificity, TanStack Start migration, Redux usage in 2025, and JavaScript's arguments object handling.
