Playwright-Lighthouse MCP server enables Claude to analyze website performance by combining Playwright's browser automation with Lighthouse's auditing capabilities. Built with TypeScript, it offers two main tools: 'run-lighthouse' for comprehensive performance analysis across multiple categories (performance, accessibility, SEO, etc.) with detailed improvement recommendations, and 'take-screenshot' for capturing full or partial webpage images. The server automatically handles browser sessions, generates performance reports with color-coded scores, and saves outputs to local directories, making it valuable for web developers seeking to identify and address performance bottlenecks directly within Claude conversations.
