Audits web performance with Chrome DevTools MCP: measures Core Web Vitals, identifies render-blocking resources, network chains, layout shifts, caching issues, and accessibility gaps. For page load optimization.
Diagnoses web performance issues, fixes Core Web Vitals (LCP, INP, CLS), optimizes bundles, assets, and render performance. Use for slow pages or dropping traffic due to speed.
