Summary
Queries DNS records through Cloudflare's resolver with support for A, AAAA, MX, TXT, CNAME, and NS lookups. This is a straightforward wrapper around DNS queries, useful when you need Claude to troubleshoot domain configuration, verify email server setup, or check nameserver delegation without leaving the conversation. The x402 micropayment integration suggests metered usage, though the repository itself is light on implementation details. Runs as a remote server over SSE transport, so you're hitting the hosted endpoint rather than running queries locally. Reach for this when you want programmatic DNS inspection without switching to dig or nslookup.
