Lighthouse MCP Server

An MCP server that lets AI agents run web audits with Google Lighthouse through more than a dozen tools. It covers performance assessments, accessibility audits, SEO analysis, security checks and Core Web Vitals monitoring for LCP, INP and CLS with threshold checking. Other features include mobile versus desktop comparison with throttling options, custom performance budgets and persistent Chrome profiles so audits can run behind a login. It needs Node.js 22 or newer and a Chrome or Chromium browser that Lighthouse manages, and it installs in VS Code, Cursor, Windsurf, Claude Desktop or any other MCP client. A smoke test exists for profile and attach modes. Written in TypeScript under the MIT license. The project documents command line options and gives copy ready setup steps for each supported editor, so a team can add audits to an agent workflow in a few minutes.
