Documentation Overview
@domainintel/mcp
An MCP server that gives AI agents live domain intelligence: WHOIS, DNS, SSL/TLS, HTTP security headers, reputation, and subdomain discovery for any domain. It is the same analysis engine that powers DomainIntel.app.
Tools
| Tool | Returns |
|---|---|
whois_lookup | Registrar, creation/expiry/updated dates, registrant country, privacy status, nameservers |
dns_records | A, AAAA, MX, TXT, NS, CNAME, CAA records + SPF/DMARC presence + misconfiguration warnings |
ssl_certificate | Validity, issuer, expiration, days remaining, protocol, warnings |
security_headers | HSTS, CSP, X-Frame-Options and others, scored with recommendations |
domain_reputation | DNSBL / Spamhaus blocklist checks and a reputation score |
subdomain_discovery | Subdomains via Certificate Transparency logs and common-prefix probing |
full_domain_report | Every analyzer at once plus an overall A+ to F security score |
analyze_email_headers | Parses a raw email header block: SPF/DKIM/DMARC results, the Received delivery path with timing, key envelope fields, and a From-vs-Return-Path spoofing flag |
Every tool except analyze_email_headers takes a single domain argument; protocol, www., and paths are stripped automatically. analyze_email_headers takes a headers string (a pasted raw header block) instead.
