claude mcp add sitehealth-mcp -- npx -y sitehealth-mcp@0.1.1
JSON configuration (Claude Desktop, Cursor, VS Code)

  "overallGrade": "B",

How It Works

All checks use Node.js builtins (tls, dns/promises, fetch) — no external API keys, no costs, no rate limits.

audit_site("example.com")
  ├── SSL check     (tls socket)      → cert validity, expiry
  ├── DNS check     (dns/promises)    → record resolution
  ├── Email auth    (DNS TXT lookups) → DMARC, SPF, DKIM
  ├── Performance   (timed fetch)     → TTFB, page weight
  ├── Uptime        (HEAD request)    → reachability
  └── Broken links  (page crawl)     → link validation
        ↓
  Weighted score (0-100) + grade (A-F) + recommendations
