HTTPfy network & DNS tools
Free DNS, SPF/DKIM/DMARC, TLS, WHOIS, IP/ASN, blocklist, ping, traceroute and port checks. No key.The vendor's description, from its MCP Registry listing.
Every public check ran and passed. Public audit: we connect as an AI client would, list the tools and check what they say. We do not run them. How we audit

Tools (24)
As the server describes them. The labels are the server's own: it says whether each tool only reads or can change things.
- dns_lookupLook up DNS records of one type (A, AAAA, CNAME, MX, NS, SOA, TXT, SRV) for a domain using public resolvers.Read-only
- dns_propagation_checkQuery a domain on about 40 public resolvers in different regions and report which ones return which answers, to see whether a DNS change has propagated.Read-only
- dnssec_checkValidate the DNSSEC chain of trust for a domain from the root down (DS, DNSKEY, RRSIG) and report each zone as secure, insecure or broken.Read-only
- mx_lookupList the mail exchanger (MX) records of a domain with their preferences.Read-only
- spf_lookupFetch the SPF record of a domain from its authoritative name server and list its mechanisms (ip4, ip6, include, redirect, all).Read-only
- spf_validateValidate the SPF record of a domain: syntax, single-record rule, DNS lookup count (limit 10), void lookups, includes and the all mechanism.Read-only
- domain_whoisWHOIS registration data for a domain: registrar, dates, status and name servers (personal contact data is redacted by registries).Read-only
- domain_expiryRegistration and expiry dates of a domain, with the time remaining before it expires.Read-only
- ssl_certificate_checkConnect to a domain on port 443 and report the certificate chain: subject, issuer, validity dates, days remaining, SANs and chain details.Read-only
- pingPing a public host from httpfy servers (4 ICMP echo requests) and report packet loss and round-trip times. Useful to test reachability from outside your own network.Read-only
- tracerouteTraceroute to a public host from httpfy servers (up to 10 hops). Internal hops of httpfy's own network are masked.Read-only
- ip_whoisWHOIS / registry data for a public IPv4 address: ASN, network range, owner organisation and registry.Read-only
- ip_blacklist_checkCheck whether a public IPv4 address is listed on common DNS-based blocklists such as Spamhaus, Barracuda and SpamCop.Read-only
- mac_vendor_lookupIdentify the manufacturer registered for a MAC address prefix (OUI) using the IEEE registry.Read-only
- asn_lookupLook up the autonomous system (ASN) for a public IP address, or details for an ASN such as AS15169: name, country, announced prefixes and address counts.Read-only
- bimi_checkCheck the BIMI record of a domain, whether DMARC meets BIMI requirements, and whether the SVG logo and certificate URLs are reachable and well formed.Read-only
- caa_checkFind the CAA records that apply to a domain (climbing to parent domains per RFC 8659) and list which certificate authorities may issue certificates.Read-only
- certificate_transparency_searchList certificates logged in Certificate Transparency for a domain (via crt.sh): issuer, validity window and names, with a summary by issuer.Read-only
- dkim_checkCheck DKIM public keys for a domain. With a selector it checks that selector; without one it probes common selectors. Reports key type and RSA key length and flags weak or revoked keys.Read-only
- dmarc_checkFind and explain the DMARC record of a domain (policy, pct, rua/ruf, alignment) and flag weaknesses such as p=none or missing external report authorization.Read-only
- dns_reportFull DNS report for a domain: delegation from the root, every authoritative name server checked individually (reachability, recursion, TCP, consistency), SOA values, MX records and their reverse DNS,…Read-only
- domain_health_reportGrade a domain A to F across 11 checks (name servers, SOA, DNSSEC, MX, SPF, DMARC, CAA, HTTPS certificate, HTTP to HTTPS redirect, HSTS, IPv6), with a reason and fix for each failed check.Read-only
- mta_sts_checkCheck MTA-STS (TXT record and the HTTPS policy file, mode and MX patterns) and the TLS-RPT reporting record for a domain.Read-only
- port_checkCheck whether one TCP port on a public host is open, closed or filtered when tested from httpfy servers on the internet.Read-only
