Dns Lookup

Network REST API MCP network tool

Return the DNS records of a domain for one record type (A, AAAA, CNAME, MX, TXT, NS or SOA). Resolved through the public Google DNS-over-HTTPS resolver.

This page documents the MCP tool findutils:dns_lookup. See the REST reference →

This tool fetches a fixed, hard-coded public upstream — never a private host. Results depend on that upstream.
