Best MCP servers for domains and DNS

We found 391 MCP servers for domains and DNS in the catalog; these are the 15 that rank highest. The order comes from our rank, which weighs adoption, freshness, documentation and publisher identity. Nobody can pay for a place on this list. Domain Check, Porkbun (official) and WHOIS lead it. Porkbun (official), CyberSPF and Sitey — free subdomains are published by the company that makes them. Domain Check has the most GitHub stars here (306). 14 of the 15 had activity in the last 30 days. Remote servers need no local install; local ones run on your machine and can reach local files. Each entry lists why it made the list and links to its install page.
