Overview

Sitehealth delivers a complete website health audit through a single MCP tool call. It examines critical aspects like SSL validity, DNS configuration, email security protocols (DMARC/SPF/DKIM), page load performance, server uptime, and internal/external broken links. This zero-configuration tool requires no API keys, enabling instant diagnostics from any MCP-compatible client.

Key Capabilities

SSL checks: Validates certificate status, expiration dates, chain integrity, and supported protocols.
DNS verification: Inspects A/AAAA, CNAME, MX records for correctness and propagation.
DMARC/SPF/DKIM analysis: Evaluates email authentication setups to prevent spoofing and improve deliverability.
Performance metrics: Measures Core Web Vitals, load times, and resource optimization.
Uptime monitoring: Confirms site availability and response times from multiple global locations.
Broken links scan: Crawls site to detect 404s, redirects, and external link failures.

All results return in a structured JSON response for easy parsing.

Use Cases

Pre-deployment audit: Run a full scan on a staging site to verify SSL setup, DNS propagation, and absence of broken links before going live.
Routine security monitoring: Schedule weekly calls to check DMARC/SPF/DKIM compliance and uptime for production domains.
Performance troubleshooting: Identify slow-loading pages or misconfigured DNS impacting user experience.
Incident response: Quickly assess if outages stem from DNS issues, expired SSL, or server downtime post-report.

Who This Is For

Web developers building or maintaining sites, DevOps teams handling infrastructure reliability, security analysts focused on domain/email protections, and SEO specialists tracking performance and link health. Integrates into CI/CD pipelines, monitoring scripts, or chatbots for automated alerts.
