FAQ from Lighthouse Mcp

What are the runtime requirements?

Node.js 16 or later and a Chrome/Chromium browser installed on the system.

How do I install Lighthouse Mcp?

You can install via the MCP Registry, run directly with npx lighthouse-mcp, install globally with npm install -g lighthouse-mcp, or clone the repo and build locally.

What parameters does the run_audit tool accept?

It requires a url, and optionally accepts categories (array from "performance", "accessibility", "best-practices", "seo", "pwa"), device ("mobile" or "desktop", default "mobile"), and throttling (boolean, default true).

Can I get only the performance score without a full audit?
