Unique.domains MCP server
Without a tool, an assistant can only guess whether a domain name is taken. This server gives it the record: 34 million one-word names on 505 endings (TLDs), read every day.
- Hosted, nothing to install, no key:
https://mcp.unique.domains/mcp(51 tools) - On your machine:
npx -y @uniquedomains/mcp-server(55 tools without a key)
One question, one tool call. "Is get.plumbing taken?" gets this answer:
{
"name": "get.plumbing",
"status": "for_sale",
"registry": {
"createdAt": "2020-06-03",
"expiresAt": "2027-06-03",
"registrar": { "name": "GoDaddy.com, LLC", "ianaId": 146 }
},
"comps": { "count": 10, "medianUsd": 2677 }
}
