Start using HTTPfy network & DNS tools
Choose your client, copy the configuration, then enable the server in your client’s MCP settings.
Run this command in your terminal, then restart Claude Code.

Look 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.
DiscoveredCheck the BIMI record of a domain, whether DMARC meets BIMI requirements, and whether the SVG logo and certificate URLs are reachable and well formed.
DiscoveredFind the CAA records that apply to a domain (climbing to parent domains per RFC 8659) and list which certificate authorities may issue certificates.
DiscoveredList certificates logged in Certificate Transparency for a domain (via crt.sh): issuer, validity window and names, with a summary by issuer.
DiscoveredCheck 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.
DiscoveredFind 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.
DiscoveredLook up DNS records of one type (A, AAAA, CNAME, MX, NS, SOA, TXT, SRV) for a domain using public resolvers.
DiscoveredQuery 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.
DiscoveredFull 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, SPF, DMARC, DKIM and DNSSEC.
DiscoveredValidate the DNSSEC chain of trust for a domain from the root down (DS, DNSKEY, RRSIG) and report each zone as secure, insecure or broken.
DiscoveredRegistration and expiry dates of a domain, with the time remaining before it expires.
DiscoveredGrade 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.
DiscoveredWHOIS registration data for a domain: registrar, dates, status and name servers (personal contact data is redacted by registries).
DiscoveredCheck whether a public IPv4 address is listed on common DNS-based blocklists such as Spamhaus, Barracuda and SpamCop.
DiscoveredWHOIS / registry data for a public IPv4 address: ASN, network range, owner organisation and registry.
DiscoveredIdentify the manufacturer registered for a MAC address prefix (OUI) using the IEEE registry.
DiscoveredCheck MTA-STS (TXT record and the HTTPS policy file, mode and MX patterns) and the TLS-RPT reporting record for a domain.
DiscoveredList the mail exchanger (MX) records of a domain with their preferences.
DiscoveredPing 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.
DiscoveredCheck whether one TCP port on a public host is open, closed or filtered when tested from httpfy servers on the internet.
DiscoveredFetch the SPF record of a domain from its authoritative name server and list its mechanisms (ip4, ip6, include, redirect, all).
DiscoveredValidate the SPF record of a domain: syntax, single-record rule, DNS lookup count (limit 10), void lookups, includes and the all mechanism.
DiscoveredConnect to a domain on port 443 and report the certificate chain: subject, issuer, validity dates, days remaining, SANs and chain details.
DiscoveredTraceroute to a public host from httpfy servers (up to 10 hops). Internal hops of httpfy's own network are masked.
