What is the DNS Lookup API MCP server?

Most cloud and infrastructure work still happens through a UI a human drives. DNS Lookup API MCP server moves it into the conversation instead. DNS record lookup — A, AAAA, MX, TXT, CNAME, NS via Cloudflare. x402 micropayment.

The short version

Lookup DNS records (A, AAAA, MX, TXT, CNAME, NS, SOA, SRV) via Cloudflare DNS-over-HTTPS. Fast and reliable. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Getting it running

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.

The tools it exposes

The server publishes 1 tool. What each one is for:

  • network_lookup_dns — POST

Things to watch

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

How it compares

Plenty of cloud and infrastructure servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. DNS Lookup API's toolset — network_lookup_dns — is a fair guide to whether it matches your workflow. It is maintained by Br0ski777; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Frequently asked questions

It connects DNS Lookup API to MCP-compatible AI assistants such as Claude and Cursor, exposing 1 tool (network_lookup_dns) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with DNS Lookup API directly.
