11 tools offered to AI assistants

  • dns_lookup · Look up live DNS records for ONE domain. The default "common" view queries the standard set (A, AAAA, MX, NS, TXT, SOA, CNAME, CAA and more) plus a DNSSEC signed/unsigned verdict; types it did not query are listed in not_queried — request t
  • email_security_check · One call answers "is this domain's email properly secured?" — checks MX, SPF, DMARC and mail-gateway/provider detection for ONE domain. The differentiator vs a plain DNS resolver. Use when the user asks about email deliverability, spoofing
  • whois_lookup · WHOIS / RDAP registration data for ONE domain or IP — registrar, status, creation/expiry, name servers. Returns publicly published WHOIS/RDAP data as-is. Use for "who owns", "when does it expire", "registrar", "when was it registered". One
  • spf_analyze · Analyze a domain's SPF record for ONE domain — the include tree and the RFC 10-DNS-lookup-limit verdict. Use only when the question is specifically about SPF (include tree, lookup count, the `all` qualifier). For an overall "is email secure
  • dmarc_check · Fetch and parse the DMARC policy for ONE domain — presence, p= policy, and the raw record. Use for DMARC-only questions ("does this domain have DMARC", "is it p=reject/quarantine/none"). For full email posture (SPF + DMARC + MX, graded), us
  • validate · Validate the SYNTAX of an SPF or DMARC record string (no DNS lookup) — returns valid/invalid, a score, a letter grade, and a parsed breakdown. Use when the user pastes an SPF/DMARC record and asks "is this correct?".
  • dkim_discover · Discover the DKIM signing keys published for ONE domain. Returns the signing keys found, the mail providers they map to, and their selectors. Use when the user asks about DKIM, signing keys, or "does this domain sign its mail?". Note: a dom
  • blacklist_check · Check whether ONE domain or IP is listed on major email blacklists / RBLs (Spamhaus, Barracuda, SpamCop, SORBS, UCEPROTECT and more). For a domain, checks the domain itself, its website (A-record) IP AND its mail-server (MX) IPs — each verd
  • search · Search DNSai for a domain. Returns result items (id, title, url) covering that domain's DNS records, email-security posture, DMARC policy and WHOIS — pass a result id to fetch for the full data.
  • fetch · Fetch a DNSai result document by id (from search). Runs the lookup and returns the data plus a summary.
  • request_api_key · Get a FREE DNSai API key that raises the daily limit from the small shared anonymous allowance to 100 lookups/day. Pass the user's email; they receive a verification link and, once clicked, the key — no password, no signup. Call this AS SOO

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
