Gtmetrix MCP server

Connect Gtmetrix to Claude, ChatGPT, Cursor, Claude Code, Codex, Gemini, GitHub Copilot and any other MCP client, for your whole team. Metorial adds security, governance, and tracing, and gives everyone one Magic MCP URL to connect.

What you can do with the Gtmetrix MCP server

Ask your agent in plain language. Each of these maps to a real tool on the server.

  • Use the run page speed test tool in Gtmetrix
  • Use the list locations & browsers tool in Gtmetrix
  • Use the get report tool in Gtmetrix
  • Use the retest tool in Gtmetrix
  • Use the get page tool in Gtmetrix
  • Use the list pages tool in Gtmetrix

Supported Tools

run_test

Run Page Speed Test

Runs a GTmetrix page speed test on a given URL and optionally waits for the test to complete. Returns the test status and, if completed, the full report with performance metrics. Supports configuring test location, browser, report type, connection throttling, ad blocking, and more.

list_locations_browsers

List Locations & Browsers

Retrieves the available test locations and browsers for GTmetrix performance testing. Use this to discover valid location and browser IDs before running tests. Locations include supported browsers and IP addresses (useful for firewall whitelisting). Browsers include feature support flags.

get_report

Get Report

Retrieves a completed GTmetrix performance report by its report ID or test ID. Returns full performance metrics including grades, scores, Core Web Vitals (LCP, TBT, CLS), timing data, page weight, and links to resources like HAR files, screenshots, and videos. When a test ID is provided, the tool polls for test completion before fetching the report.

retest

Retest

Re-runs a performance test using the original analysis options from an existing page or report. Useful for tracking performance changes over time without reconfiguring test parameters. Optionally waits for completion and returns the new report.

get_page

Get Page

Retrieves a GTmetrix page by ID, including its metadata and optionally its latest report or historical reports list. A page groups all reports that share the same URL and analysis options.

list_pages

List Pages

Lists GTmetrix pages (URL aggregations). Each page groups reports that share the same URL and analysis options, similar to the GTmetrix Dashboard. Supports filtering by URL or monitoring status, sorting, and pagination.

get_account_status

Get Account Status

Retrieves the current GTmetrix account status including API credit balance, next refill time, account type, and feature access flags. Use this to check available credits before running tests.

delete_resource

Delete Page or Report

Deletes a GTmetrix page or report. Deleting a page also removes all its associated reports. This action is permanent and cannot be undone.

get_test

Get Test

Checks the current state of a GTmetrix test without waiting for completion. Returns the report ID when completed, or the failure details when the test failed.

list_tests

List Tests

Lists recent GTmetrix tests with status and report IDs. Supports filtering by state and source, sorting, and pagination to recover queued tests and retrieve completed reports.

list_simulated_devices

List Simulated Devices

Lists GTmetrix simulated-device presets with IDs, viewport dimensions, pixel ratios, and user agents. Pass a device ID to run_test as simulateDevice.

Connect Gtmetrix to your AI client

Every client uses the same Magic MCP URL, and so does any other MCP client. Add it once and sign in with SSO.

  1. Enable Gtmetrix in Metorial. In your Metorial portal, enable the Gtmetrix MCP server and sign in with the account that owns the data. Access stays governed by your team policies.
  2. Add a custom connector. Open Customize, then Connectors. Select Add, then Custom, then Web.
  3. Paste your Metorial MCP URL. Name it Metorial, paste your Magic MCP URL (<your-magic-mcp-url>) and continue.
  4. Sign in. Select Add and sign in to load Gtmetrix tools.

Run Gtmetrix through the Metorial gateway

One governed layer for every app your agents reach, not a separate connector per tool.

  • Give Gtmetrix and every other app to your whole team through one MCP gateway, behind your SSO.
  • Scope which teams and agents can use Gtmetrix tools with role-based access control, and trace every call.
  • Prefer to run it yourself? Metorial is open source and self-hostable.
