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

- 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)
Quick Start
{
"mcpServers": {
"sitehealth": {
"command": "npx",
"args": ["-y", "sitehealth-mcp"]
}
}
}
Then ask your AI agent:
"Audit the health of example.com"

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:dmarc@example.com",
"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
Scoring Weights
| Check | Weight |
|---|---|
| SSL | 20% |
| Performance | 20% |
| Uptime | 20% |
| Email Auth | 15% |
| Links | 15% |
| DNS | 10% |
