Google has recently unveiled the public beta of 'Chrome DevTools MCP,' a server built on the Model Context Protocol (MCP). This innovative server empowers AI coding agents to control and scrutinize actual instances of the Chrome browser. It is capable of recording performance metrics, inspecting the Document Object Model (DOM) and Cascading Style Sheets (CSS), and effectively addresses the longstanding issue of code-generating agents being unable to observe a page's runtime behavior. By doing so, it transforms static suggestion engines into dynamic, closed-loop debuggers.

As an open protocol, MCP is designed to bridge the gap between large language models and a variety of tools and data sources. Meanwhile, DevTools MCP extends Chrome's debugging capabilities to clients that are compatible with MCP. Google's official GitHub repository boasts an extensive array of tools. The server's automation foundation is implemented using Puppeteer, and its communication with Chrome is facilitated through the Chrome DevTools Protocol.

Setting up MCP clients is a breeze, and the server seamlessly integrates with multiple agent frontends. It is tailored for a runtime environment that includes Node.js version 22 or higher and the latest iteration of Chrome. In its announcement, Google provided illustrative agent workflows, enabling users to carry out real-world measurements and verification tasks. The server stands out for its real-time control capabilities, comprehensive feature set, and straightforward installation process.
