Nothing serious here today

Today is the operative word: we check Domain Intelligence every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 6

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

dns

dns_records

DNS records for a domain: A, AAAA, MX, TXT, NS, CAA and SOA, resolved in parallel.

domain

domain_lookup

Full report on a domain in one call: WHOIS/RDAP registration, DNS records, live SSL certificate, subdomains (live hosts with IPs first) and email authentication (SPF, DMARC, DKIM). Use it to triage a suspicious domain or profile a company's domain. If one section fails it comes back as an object with an `error` field and the rest is unaffected. Set wait=true to wait for every subdomain source (up to about 20 s) instead of the fast first result.

email_security

Email authentication for a domain: SPF and DMARC records, and DKIM keys found by probing about 29 common selectors (Google, Microsoft 365, Mailchimp, SendGrid and others). Custom selectors may not be found.

ssl

ssl_certificate

The certificate a domain serves on port 443, from a live TLS handshake: issuer, subject, valid_from, valid_to, days_until_expiry, SANs, signature algorithm and serial number.

subdomains

subdomains

Subdomains of a domain from certificate transparency logs, passive DNS and DNS brute force. `live` lists hosts that resolve now, each with its IP; `subdomains` lists every name found, live first; `pools` summarises large shared-infrastructure zones. The first lookup of a domain is a fast snapshot and later ones are fuller; set wait=true to wait for every source (up to about 20 s).

whois

whois_lookup

Registration data for a domain: registrar, created, updated and expiry dates, nameservers and status. RDAP first (rdap.org, IANA bootstrap, 22 fallback servers), then port-43 WHOIS for 60+ TLDs. `_source` says which one answered. Use it for domain age, expiry or registrar checks.

Domain Intelligence — questions

Answers built from our own checks of this server.

What can Domain Intelligence do?

It exposes 6 tools, read directly from the server on our last check. Among them: dns_records, domain_lookup, email_security, ssl_certificate, subdomains, whois_lookup. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Domain Intelligence working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 398 ms. The bar chart above shows every period we have measured.

How do I connect Domain Intelligence?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Domain Intelligence need an API key?

No. Domain Intelligence completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Domain Intelligence?

It answers our handshake in 398 ms on average, which is faster than 31% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Domain Intelligence open source?

Yes — it is published under the MIT licence, written in Python and 14 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
