Tool names and descriptions exactly as the server reported them on Nov 11, 2026. The maker wrote them, not us; we show them as plain text.
dns_lookupLooks up DNS records (A, AAAA, CNAME, MX, NS, TXT, SOA or CAA) for a domain through a public resolver. Use dig for other record types or for a specific nameserver.
dns_propagationAsks several public resolvers around the world for the same record and reports whether they agree, which shows whether a DNS change has propagated.
dnssec_checkChecks whether a domain is signed with DNSSEC and whether its chain of trust (DS and DNSKEY records) is consistent.
mx_checkLists the mail servers (MX records) of a domain with their priorities and checks that they resolve.
spf_checkReads and validates a domain's SPF record: syntax, the 10-lookup limit, includes and the final policy.
dmarc_checkReads and validates a domain's DMARC record: policy, reporting addresses, alignment and percentage.
dkim_checkLooks up and validates a DKIM public key. Give the selector if you know it; otherwise the common selectors are tried.
bimi_checkChecks a domain's BIMI record and logo (SVG) for brand indicators in email clients.
email_blacklist_checkChecks whether a mail server IP address or a domain is listed on public DNS blocklists. Give exactly one of ip or domain.
email_deliverability_reportScores a domain's email setup (MX, SPF, DKIM, DMARC, MTA-STS, TLS-RPT, BIMI, blocklists) and lists what to fix. Use this first for a general email health question.
whois_lookupLooks up a domain's registration data over RDAP: registrar, creation, expiry and update dates, status and nameservers. Not every country code TLD publishes RDAP.
hosting_checkFinds out who hosts a website: the IP addresses, the network and organisation behind them, the nameservers and any CDN in front.
redirect_checkFollows a URL's redirects hop by hop and reports each status code, the final address and problems such as loops, long chains or http-to-https gaps.
http_headers_checkFetches a page and reports its response headers, with a review of the security headers (HSTS, CSP, X-Frame-Options and others) and cookie flags.
website_down_checkChecks whether a website is reachable from Cloudflare's network: DNS first, then one request. Separates 'does not resolve' from 'will not connect' and 'answers with an error'.
robots_txt_testFetches a site's robots.txt and tests whether a given crawler may fetch a given path, following RFC 9309. Also lists the Sitemap lines and parser warnings.
sitemap_checkFinds a site's XML sitemap (from robots.txt or the usual addresses), then validates it against the sitemaps.org protocol and Google's rules. Reads at most 5 MB; a sitemap index is validated as an index, its child sitemaps are listed but not fetched.
url_status_checkFetches up to 10 URLs from one site and reports each one's final status code, redirects, content type and X-Robots-Tag. Useful for spot-checking pages listed in a sitemap.
ip_lookupDescribes a public IP address: the announced prefix and AS number, the network's name, country, registry and the reverse DNS name.
asn_lookupLooks up an AS number (like AS13335) in Team Cymru and RDAP: the network's name, organisation, country, registry and registration dates. An IP address is mapped to the AS that announces it first.
reverse_dnsFinds the PTR (reverse DNS) name of an IP address and checks that the name resolves back to the same address (forward-confirmed reverse DNS), which mail servers look for.
ssl_checkMakes live TLS connections to a host and reports the certificate chain, expiry, protocol versions, cipher strength and common misconfigurations. Ports 443, 8443, 465, 993 and 995.
smtp_testConnects to a domain's mail servers (MX) on port 25, says EHLO, tries STARTTLS and reports banners, TLS and reverse DNS. It never sends mail.
digSends a DNS query like the dig command, to Cloudflare, Google, Quad9 or a nameserver you name, and returns the full answer with flags and sections. Supports many record types, DNSSEC data and TCP.
dns_traceFollows a name from the root servers down through the TLD to its authoritative nameservers, like dig +trace, and shows each delegation step.
tracerouteTraces the network path from the probe server in Germany to a host, showing each hop's address and round-trip times.
http3_testChecks whether a site supports HTTP/2 and HTTP/3 (QUIC): ALPN negotiation, the Alt-Svc header and a live QUIC handshake probe.
ttfb_testTimes three requests to a web address from the probe server in Germany: DNS, connect, TLS, time to first byte and download. Results are never cached.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (1.0.2) reached the registry yesterday.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).
