## Description

This MCP server provides comprehensive Lighthouse performance analysis capabilities through automated web performance auditing and deep analysis tools. Built with TypeScript and featuring integration with Google's Lighthouse engine, Puppeteer, and Chrome launcher, it offers four core tools: URL analysis with configurable device types and audit categories, deep analysis with critical request chain examination and unused code detection, batch analysis for multiple URLs in parallel, and prompt generation for AI-assisted performance optimization workflows. The implementation includes specialized analyzers for Core Web Vitals, performance patterns, problem detection, and score breakdowns, with browser pool management for efficient parallel processing and comprehensive reporting that generates prioritized recommendations with impact assessments, making it ideal for web developers, performance engineers, and automated CI/CD pipelines that need programmatic access to detailed website performance insights and optimization guidance.
