Description

This server wraps Google's Lighthouse to run comprehensive audits on given URLs and return performance scores and audit metrics. It supports device emulation (mobile/desktop), optional network throttling, and selection of specific audit categories (performance, accessibility, best-practices, SEO, PWA). Installation options include npx, global npm install, or local development, and it is designed to be integrated with MCP clients like Claude for automated site analysis. The tool is useful for automating performance checks, debugging regressions, and embedding Lighthouse data into agent workflows or CI pipelines.
