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

domain

domain_diagnose

Runs a comprehensive health check on a public domain: SPF / DKIM / DMARC for the headline score, plus optional details on email-auth adjacent records (MX, BIMI, MTA-STS, TLS-RPT, DKIM key length), DNS infrastructure (NS, DNSSEC, CAA, AAAA, SOA, TXT), web security (HTTPS, certificate, HSTS, HTTP/2-3, CT log), domain registration (RDAP expiry, registrar lock, DS chain), and brand protection (typosquatting, TLD parity). Returns a structured report with per-category scores, individual diagnostic items, and a `critical_issues` cross-cut summary. No authentication required.

ドメイン番人 — questions

Answers built from our own checks of this server.

What can ドメイン番人 do?

It exposes 1 tools, read directly from the server on our last check. Among them: domain_diagnose. 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 ドメイン番人 working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 85 of 91 checks got a reply (93.4%), average response time 530 ms. The bar chart above shows every period we have measured.

Is ドメイン番人 still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect ドメイン番人?

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 ドメイン番人 need an API key?

No. ドメイン番人 completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is ドメイン番人?

It answers our handshake in 530 ms on average, which is faster than 28% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
