isitdns is a remote MCP server that gives an AI agent 8 tools, among them check_domain, dig, dns_events. It answers at https://isitdns.net/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 12 September 2026; the last check, on 24 October 2026, succeeded.
Live DNS: dig public resolvers, audit or sweep a domain, walk a delegation, read the resolver board.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
check_domain | The eleven-check DNS audit for a domain: parent and child nameservers agree, no open recursion, DNSSEC chain, TTL sanity, mail posture, glue at the parent, a DS that matches a live DNSKEY, and whether a truncated UDP answer can be had over Inputs: name |
dig | Ask a public DNS resolver, or any public address, for a record, live, from the isitdns seat. Returns the answer, the flags, the rcode, Extended DNS Errors and the latency in the shape dig prints, plus the JSON. Inputs: name, type, resolver, transport, dnssec, cd |
dns_events | Days when several resolvers were unhealthy at once, as episodes: when each began, how long it ran, how many resolvers were affected at the peak, and which. This is the tool for "was there a DNS outage recently". |
ksk_board | The RFC 8509 root key sentinel across the public resolvers: which resolvers trust which root KSK, and the root DNSKEY set as read now. |
resolver_history | The incident record for the public resolvers: start time, duration and severity of each. Notable incidents by default; all=true includes short degradations. Windows where several operators failed at once are excluded as our own seat's path, Inputs: resolver, all |
resolver_status | The live board: is public DNS OK right now? Every public resolver isitdns watches, its latest reading (status, latency, DNSSEC), read every 3 minutes over DoT, with the time it was read. Give a resolver to get one card. Inputs: resolver |
top_domains | The DNS health of the top 100 domains as of the last DAILY snapshot: rcode, addresses, DNSSEC and rank movement for each. Those come from one probe per day at 11:11:11 UTC and do not move intraday. The nameservers and the points are read se Inputs: domain |
trace | Walk the delegation from the root servers down to the authoritative server for a name, like dig +trace, and say in plain steps whether the delegation is healthy. Inputs: name, type |

It answered our last check on 24 October 2026 in 247 ms. Over 6 checks since 12 September 2026 it answered 6. Status here comes from Neuronto's own probes, not from the publisher.
Yes. It is published by isitdns.net and served from isitdns.net, the vendor's own domain: https://isitdns.net/mcp.
8, as returned by the server's own tools/list on 22 September 2026: check_domain, dig, dns_events, ksk_board, resolver_history, resolver_status, top_domains, trace.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://isitdns.net/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
