About SiteHealth MCP
SiteHealth MCP audits a website’s certificates, DNS, email authentication, performance, uptime, and links, then produces a scored report. It is for users checking website health through an MCP client; some checks and the full audit are listed as Pro features.
Key features
- 01Inspect SSL certificates and DNS records
- 02Validate DMARC, SPF, and DKIM
- 03Measure response and page performance
- 04Check uptime and broken links
- 05Generate a weighted health score
Use cases
- 01Review a site’s configuration and security
- 02Investigate email authentication problems
- 03Check page speed and availability
- 04Find links returning 4xx or 5xx
MCP support
The MCP server exposes tools for a full site audit and individual SSL, DNS, email authentication, performance, uptime, and link checks. The README describes free SSL and DNS checks and Pro access for the full audit and other checks.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.

- 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:[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

| SSL | 20% |
| Performance | 20% |
| Uptime | 20% |
| Email Auth | 15% |
| Links | 15% |
| DNS | 10% |

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
