Before you install Pagespeed Insights MCP

AgenticMart scanned Pagespeed Insights MCP on Nov 5, 2026 with automated checks for hidden code, known-malicious packages, leaked secrets and vulnerable dependencies. The result covers one commit under our scan policy, so review what access you give it and check any advisories shown here.

What it can access

  • An MCP server is a program your AI app starts and talks to. A local one runs with your user's permissions: it can see the files, environment variables and network your account can.
  • Based on its description and topics, it likely needs to control a web browser (visit sites, fill in and submit forms).

Before you install

  1. Run it in a separate browser profile without your logged-in accounts.
  2. Pin the version you reviewed instead of always installing the latest release.
  3. Read the tool list or scripts before the first run, and keep approval prompts on for actions that write, send or delete.

  • Last code change: Oct 26, 2026.
  • Open-source license: Apache-2.0.

Tools Pagespeed Insights MCP exposes (6)

Listed by the server itself during our scan of commit 91d19a8.

  • pagespeed_analyze_page

    Run a PageSpeed Insights Lighthouse analysis for one public page. Start with report=summary for a health check; choose full for audits, recommendations for a prioritized fix list, audit for non-performance categories, or performance-map for Mermaid. Example: analyze a mobile product page and return

  • pagespeed_diagnose_page

    Inspect one page through exactly one diagnostic lens: visual, elements, network, javascript, images, render-blocking, or third-parties. Use after pagespeed_analyze_page identifies a problem; do not use it for a general score. Example: focus=render-blocking to identify CSS/JS delaying first render. R

  • pagespeed_get_field_data

    Get real-user Core Web Vitals from Chrome UX Report, not Lighthouse lab measurements. Use scope=page for one URL; use scope=origin with a bare origin when the page has insufficient traffic. Example: check mobile LCP and INP for https://example.com/checkout. Returns p75 field metrics or a clear no-da

  • pagespeed_compare_pages

    Compare two pages now (mode=pages) or measure one page against its locally stored baseline (mode=baseline). Baseline mode records the first call; use runs=3 or more and rely on guaranteed deltas, not medians alone. Example: compare staging against production, or verify whether a deployed fix improve

  • pagespeed_analyze_batch

    Analyze 1–10 public URLs and return per-page results plus success/failure counts. Use pagespeed_analyze_page for one URL or pagespeed_compare_pages for a direct comparison. Example: triage the ten highest-traffic landing pages. Progress notifications are emitted when supported by the client.

  • pagespeed_clear_cache

    Clear only this server process's in-memory PageSpeed response cache, forcing later analysis calls to contact Google again. Use after a deploy when a cached result is stale. It does not change the target website, files, or remote data; repeating the call is safe.
