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

check_email_dns

Use this when the user wants an email DNS check, a DMARC checker, an SPF record checker, a DKIM checker, or an MX lookup for a domain. Reads the live public DNS records through DNS-over-HTTPS and returns MX hosts, the SPF record with its DNS-lookup count against the limit of 10, the DMARC policy, reporting and alignment, DKIM keys for the selectors you give, and a pass/warn/fail findings list with a fix and a CSV report. Do not use for internal DNS server visibility, full deliverability tests, or reading or sending mail.

lookup

lookup_dns_records

Use this when the user wants a dns lookup, an mx record check, or a txt record lookup for a domain. Reads live public DNS records through DNS-over-HTTPS and returns A, AAAA, MX, NS, TXT, CNAME, CAA, and SOA records with their TTLs, plus a CSV report. Do not use for internal DNS server visibility, reverse DNS of an IP address, or records outside the supported type list.

Zovo DNS Checker — questions

Answers built from our own checks of this server.

What can Zovo DNS Checker do?

It exposes 2 tools, read directly from the server on our last check. Among them: check_email_dns, lookup_dns_records. 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 Zovo DNS Checker working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 216 ms. The bar chart above shows every period we have measured.

How do I connect Zovo DNS Checker?

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

Does Zovo DNS Checker need an API key?

No. Zovo DNS Checker completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Zovo DNS Checker?

It answers our handshake in 216 ms on average, which is faster than 68% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
