PageSpeed Insights MCP

PageSpeed Insights MCP audits web pages through Google's PageSpeed Insights and Chrome UX Report (CrUX) APIs. Version 2.0.0, released 2026-08-26, collapsed an earlier set of nineteen endpoint-shaped tools into six workflow tools: pagespeed_analyze_page, pagespeed_diagnose_page, pagespeed_get_field_data, pagespeed_compare_pages, pagespeed_analyze_batch and pagespeed_clear_cache. The server is distributed as the npm package pagespeed-insights-mcp and runs over stdio only; it requires callers to supply their own Google API key through a required GOOGLE_API_KEY environment variable, since it calls Google's public API rather than any endpoint of its own.

The maintainer, ruslanlap, is an individual developer based in Ukraine who publishes the npm package under a personal Gmail maintainer address and lists no employer. The README instructs every user to generate their own Google Cloud API key rather than pointing at any Google-operated credential or endpoint, consistent with an independent client wrapper rather than a Google-published integration. Because the server fronts Google's API without being published by Google, authority is community.

No surface names a supported MCP specification revision: the README, CHANGELOG.md and the fetched documentation pages contain no reference to a protocol revision date. The package depends on @modelcontextprotocol/sdk ^1.30.0, but a dependency range is not evidence of which revision the server implements, so spec_status remains unknown.
