Summary
Gives Claude five tools to analyze websites without needing API keys or external services. It fetches pages over HTTP and parses HTML locally to check SEO fundamentals (titles, meta tags, Open Graph, structured data), scan for accessibility issues (ARIA landmarks, alt text, form labels), audit security headers, crawl and test all links for 404s and timeouts, and compare two URLs side by side across all metrics. The check_website tool runs a full health check in one call. Useful when you're auditing a site, debugging broken links, or need to explain SEO problems to Claude with real data instead of guessing. Works offline and sends nothing to third parties.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.
