NsLookup.io

listing.about

Connects an assistant to nslookup.io for DNS and domain intelligence. It can look up 53 DNS record types, check propagation across 18+ global DNS servers, inspect SSL/TLS certificates, verify BIMI/VMC records, audit DNS health, scan SPF/DKIM/DMARC and web security, run RDAP lookups, identify hosting providers, and test website availability from 7 locations. It can also review proposed DNS changes before they are applied.

The hosted endpoint is a Streamable HTTP server. The 17 public tools work with no sign-in or API key. Six my_ tools read your own NsLookup.io monitoring account (monitors, incidents, uptime history, DNS changes, certificate expiry) and need a browser OAuth sign-in. A local npx package offers the public tools only.
