Chrome DevTools MCP: AI Agents Now Debug Code in Real Time

Google launched support for the Model Context Protocol (MCP) in Chrome DevTools, a change that fundamentally transforms how AI agents assist developers in the debugging process. ## What is MCP in Chrome's context? MCP allows AI agents to connect to external tools in a standardized way. With Chrome DevTools integration, an AI agent like Claude or GPT-4 can now inspect the DOM in real time, read console state, analyze network requests, access performance profiles, and execute scripts in the current page's context. ## Security implications This capability brings risks that need to be addressed: a compromised agent with DevTools access can exfiltrate session tokens, cookies and sensitive data. The permission to run arbitrary scripts in the page context is extremely powerful — and dangerous. In corporate environments, access to production DevTools must be strictly controlled.
