常见问题

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?

Yes, the `get_performance_score` tool returns just the performance score for a URL, with an optional `device` parameter.

Does Lighthouse Mcp work with Claude Desktop?

Yes, it is designed for use with MCP clients including Claude Desktop; example usage shows asking Claude for a performance score.
