Domainintel MCP Server

Domain intelligence for agents: WHOIS, DNS, SSL/TLS, security headers, reputation, subdomains.

What is the Domainintel MCP server?

If you already use Domainintel, the domainintel mcp server is the piece that lets your assistant work with it directly. Domain intelligence for agents: WHOIS, DNS, SSL/TLS, security headers, reputation, subdomains.

What the server does

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.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • 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

Installation

@domainintel/mcp on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Credentials and setup notes

  • Node.js 18 or newer

Where it fits

Plenty of team communication servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Domainintel's toolset — whois_lookup, dns_records, ssl_certificate and 5 more — is a fair guide to whether it matches your workflow. It is maintained by Bishop81; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Worth knowing first

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Frequently asked questions

It connects Domainintel to MCP-compatible AI assistants such as Claude and Cursor, exposing 8 tools (whois_lookup, dns_records, ssl_certificate, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Domainintel directly.
