Exposes six tools: audit_site for full reports, quick_check for fast scores, and focused audits for accessibility (47 WCAG 2.1 AA checks with criterion references), performance, and SEO. Also includes compare_sites for side-by-side URL analysis. Built with EU Accessibility Act compliance in mind, flagging sites as compliant, partial, or non-compliant based on WCAG standards. Checks everything from alt text and ARIA landmarks to Open Graph tags, structured data, viewport config, and touch target sizes.
