Tool changes

2026-10-18ip_lookupremoved
Look up an IP address or ASN: owner organization, announced prefix, PTR (reverse DNS), RPKI validity and geolocation. Use to identify who is behind an address seen in logs, or to check PTR/RPKI for a mail or BGP issue.
2026-10-18check_ipadded
Look up an IP address or ASN: owner organization, announced prefix, PTR (reverse DNS), RPKI validity and geolocation. Use to identify who is behind an address seen in logs or headers, or to check PTR / RPKI for a mail or BGP issue. Does not test reachability (use check_port).
2026-10-18check_portchangeddescription, input schema, output schema, annotations
before
Check from the internet whether TCP ports of a public host are open, closed or filtered. Use to verify firewall / security group rules, or why a service is reachable locally but not from outside. Only public addresses are allowed.
after · 65% of words in common
Check from the internet whether TCP ports of a public host are open, closed or filtered. Use to verify firewall / security group rules, or to find out why a service works locally but is unreachable from outside. Only public addresses are accepted; this does not test the application behind the port (use check_http or check_tls for that).
2026-10-18check_dnschangeddescription, input schema, output schema, annotations
before
Resolve a name at several public resolvers (Google, Cloudflare, Quad9, …) and compare answers. Use after changing DNS records to check propagation, or when some users reach a different IP or get NXDOMAIN. Returns per-resolver answers and inconsistencies.
after · 77% of words in common
Resolve a name at several public resolvers (Google, Cloudflare, Quad9, …) and compare their answers. Use after changing DNS records to check propagation, or when some users reach a different IP or get NXDOMAIN. Use check_email_domain instead for SPF/DKIM/DMARC analysis. Returns per-resolver answers, inconsistencies and a verdict.
2026-10-18check_email_domainchangeddescription, input schema, output schema, annotations
before
Audit a mail domain as other mail servers see it: MX, SPF (with 10-lookup count), DKIM, DMARC, PTR/FCrDNS, SMTP STARTTLS, MTA-STS, TLS-RPT, BIMI. Use when mail lands in spam or bounces, after changing mail provider or DNS, or before tightening DMARC. Returns a verdict, findings with cause and fix, and a report link.
after · 69% of words in common
Audit a mail domain as other mail servers see it: MX, SPF (including the 10-DNS-lookup limit), DKIM, DMARC policy, PTR / forward-confirmed reverse DNS, SMTP STARTTLS on the MX hosts, MTA-STS, TLS-RPT, BIMI. Use when mail lands in spam or bounces, after changing mail provider or DNS, or before tightening DMARC. Use this (not check_dns) for any email deliverability or authentication question. Returns a verdict, findings with cause and fix, and a report link.
2026-10-18check_httpchangeddescription, input schema, output schema, annotations
before
Fetch a public URL from outside your network: status, redirect chain, TLS, security headers (HSTS, CSP, X-Frame-Options…), caching and compression. Use to debug redirect loops, wrong status codes or missing headers as real visitors and CDNs see them, or to verify a web server config change after deploy. Returns a verdict and findings with fixes.
after · 69% of words in common
Request a public URL from outside your network and inspect the HTTP layer: status code, full redirect chain, security headers (HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy…), caching and compression headers. Use to debug redirect loops, unexpected status codes or missing headers as real visitors and CDNs see them, or to verify a web server / CDN config change after deploy. Use check_tls instead for certificate or TLS protocol questions. Returns a verdict and findings with fixes.
2026-10-18check_tlschangeddescription, input schema, output schema, annotations
before
Scan a public host's TLS from the internet: certificate validity and chain, expiry, hostname match, protocols (TLS 1.0–1.3), ciphers, HSTS. Use when a site shows certificate errors, before/after renewing or rotating a certificate, or to confirm old TLS versions are off. Returns a verdict, findings with cause and fix, and a shareable report link. Takes up to ~60 s.
after · 63% of words in common
Scan a public host's TLS from the internet: certificate validity, chain completeness, expiry date, hostname match, enabled protocols (TLS 1.0–1.3), cipher suites, HSTS. Use when browsers show certificate errors, before/after renewing or rotating a certificate, or to confirm old TLS versions are disabled. Use this (not check_http) for anything about the certificate or TLS configuration itself; works on any TLS port, not only 443. Returns a verdict, findings with cause and fix, and a shareable report link. Takes up to ~60 s.
