What is the Google Lighthouse SEO Auditor MCP Server?
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.
Built-in capabilities (1)
Returns the scores (0-100) and specific failed audits (e.g. large images, render-blocking JS) so you can suggest exact code fixes. Runs a full Google PageSpeed Insights (Lighthouse) audit on any public URL
