Resolve DNS records (A/AAAA/MX/TXT/CNAME/NS/SOA/SRV/PTR/ANY) for any hostname via @mukundakatta/dns-mcp — 1 tool, credential-free

intentresolve DNS records for a hostname — A records for IPs, AAAA for IPv6, MX for mail servers with priorities, TXT for SPF/DKIM/verification, CNAME for aliases, NS for nameservers, plus SOA/SRV/PTR/ANYconstraints

@mukundakatta/dns-mcp v0.1.0 — DNS record resolution

Install: npm install @mukundakatta/dns-mcp Entry: dist/server.js Transport: stdio Tools: 1 (resolve)

Tool: resolve

ParamTypeRequiredNotes
hostnamestringyesDomain or hostname to resolve
typeenumnoA, AAAA, MX, TXT, CNAME, NS, SOA, SRV, PTR, ANY. Default: A

Key findings

  • 10 record types from a single tool — A/AAAA/MX/TXT/CNAME/NS/SOA/SRV/PTR/ANY
  • Uses Node.js built-in `dns.promises` — no external DNS service, resolves through system resolver
  • MX records include both exchange and priority fields (sorted by priority)
  • TXT records return arrays-of-arrays (one inner array per TXT record, matching DNS spec for multi-string TXT)
  • Non-existent domains return isError: true with descriptive message (queryA ENOTFOUND ...)
  • CNAME returns the canonical hostname as a flat string array
  • No TTL exposed in the response (Node dns module limitation)
  • First call ~58ms, subsequent calls 19-66ms (no JIT warm-up, just DNS latency)
  • p50 latency: ~40ms (network-bound, varies by DNS server)

Gotchas

  • No custom DNS server option — always uses system resolver
  • No reverse DNS via PTR on raw IPs — you must construct the .in-addr.arpa hostname yourself
  • TXT double-nested arrays can surprise: each TXT record is ["string"] inside an outer array, so records[0][0] gets the first TXT value
