SiteHealth MCP
Runs a full site health audit using Node.js builtins with no external API dependencies. Exposes six discrete checks (SSL cert validity and expiry, DNS record resolution, DMARC/SPF/DKIM email auth, TTFB and page weight performance metrics, uptime pings, and broken link crawling) plus a combined audit_site tool that runs all checks and outputs a weighted 0-100 score with letter grade. Free tier includes SSL and DNS checks only. Pro tier unlocks the full audit suite, scoring engine, and actionable fix recommendations. Reach for this when you need programmatic website diagnostics without managing API keys or external service dependencies.
