🔥 What Makes It Different
Most PageSpeed MCP servers wrap one tool: "run PSI on a URL." This server ships six workflow tools covering the full performance workflow — not just a score, but an action plan:
- Full toolkit: page analysis, CrUX real-user data (URL + origin), Lighthouse audits, multi-page & batch comparison, baselines, and regression tracking
- Deep diagnostics: element-level, network, JavaScript, image optimization, render-blocking, and third-party impact analysis
- Actionable output: a recommendations engine that turns raw Lighthouse data into prioritized fixes, plus visual analysis of screenshots
- Practical extras: caching for repeat runs and smart recommendations tuned for AI agents to act on
- Battle-tested: published on npm, listed in the Official MCP Registry and Glama, CI-tested with Vitest
