SiteHealth MCP

Full website health audit in one MCP tool call. Zero API keys required.

One call. Six checks. Scored report.

One-click install: Install on MCPize | npx sitehealth-mcp

Features

• SSL Certificate — validity, expiry, issuer, protocol, SANs

• DNS Health — A/AAAA/MX/NS/CNAME/TXT/SOA, IPv6, resolution time

• Email Auth — DMARC, SPF, DKIM validation with fix recommendations

• Page Performance — TTFB, load time, page weight, compression, caching

• Uptime — HTTP ping with response time

• Broken Links — extract and check page links for 4xx/5xx responses

• Health Score — weighted 0-100 score with letter grade (A-F)

Tools

Tool Description audit_site Full audit — all 6 checks, scored report check_ssl SSL cert validity and expiry check_dns DNS records and resolution check_email_auth DMARC/SPF/DKIM validation check_performance TTFB, load time, page weight check_uptime HTTP ping + response time check_links Broken link detection

Example Output

{ "url": "https://example.com", "overallScore": 82, "overallGrade": "B", "criticalIssues": [ "No DMARC record — required by Gmail/Yahoo/Microsoft for deliverability" ], "warnings": [ "SSL certificate expires in 28 days — renew soon", "2 broken links found out of 47 checked" ], "recommendations": [ "Add a DMARC record: v=DMARC1; p=quarantine; rua=mailto: [email protected] ", "Enable gzip/brotli compression to reduce transfer size" ] }

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
