Stop paying agencies thousands of dollars for performance audits. This MCP connects your AI agent directly to the official Google PageSpeed Insights API, turning it into an elite Technical SEO and Frontend expert.

The Superpowers

  • Instant Competitor Analysis: Ask the AI to audit a competitor's website. It will run a full Lighthouse scan (Mobile or Desktop) and return their exact scores for Performance, Accessibility, Best Practices, and SEO.
  • Actionable Code Fixes: Unlike a normal dashboard that just tells you "Render-blocking resources found", the AI reads the specific failing audits and writes the exact React, Next.js, or HTML code you need to copy/paste to fix it.
  • Zero Friction: No authentication required for standard use. Just connect the MCP and start auditing websites immediately. Your AI agent can now visually optimize web applications on the fly.

Audit the performance of https://vinkius.com on mobile and tell me how to get to 100/100.

I've ran the Lighthouse audit. **Scores:** Performance: 72, Accessibility: 95, SEO: 100. The main issue dragging your Performance down is a **Render-blocking resource** (`main.js` taking 1.2s to load). To fix this, add the `defer` attribute to your script tag. I will update your `index.html` file now to implement this change.

Run an accessibility audit on https://github.com to see if they missed anything.

I audited GitHub's homepage. They scored **100/100 on Accessibility**. However, the Best Practices score is 83/100 because of an issue with a third-party cookie missing the `SameSite` attribute. As developers, we can learn from their flawless ARIA role implementation.
