Chrome DevTools MCP review
Google Chrome DevTools team's local MCP server for SEO. What it can reach, what it costs and who should connect it.
Our verdict
Free, official and genuinely useful for Core Web Vitals work: the agent measures a real browser instead of guessing. Remember it's lab data, not the real-user field data Google ranks on.
Why it's on our list
Chrome DevTools MCP is the Chrome team's official server that lets an agent drive a real Chrome browser, record performance traces, analyse Core Web Vitals insights and run Lighthouse audits. It's here because it's free and covers page speed, the SEO job most data servers skip.
