Wraps Google's Lighthouse performance auditing tool so AI assistants can programmatically analyze webpage metrics. Exposes two main operations: run comprehensive audits across performance, accessibility, SEO, and PWA categories, or grab just the performance score. You can configure device emulation and network throttling. The real power comes from combining this with agentic workflows where your AI can audit a site, identify bottlenecks, suggest optimizations, then re-audit to measure improvements. Works with any MCP-compatible assistant and requires Chrome/Chromium for the underlying Lighthouse engine.
