![MCP Server](https://badge.mcpx.dev?type=server&features=tools 'Model Context Protocol Server') [![MCP Enabled](https://badge.mcpx.dev?status=on 'MCP Enabled')](https://modelcontextprotocol.io)

MCP server for checking domain name availability. Supports 500+ TLDs via RDAP, with WHOIS fallback for .de and .cn.

Installation

uvx domain-check-mcp

Usage in .mcp.json

{
  "mcpServers": {
    "domain-check": {
      "command": "uvx",
      "args": ["domain-check-mcp"]
    }
  }
}

Tools

check_domain — Check if a domain name is available for registration

Example

check_domain("example.com")

Returns:

{
  "domain": "example.com",
  "available": false,
  "status": "registered"
}

Supported TLDs

Via RDAP (500+)

All major gTLDs and many ccTLDs with RDAP support, sourced from the IANA RDAP Bootstrap:

.com, .net, .org, .info, .app, .dev, .io, .xyz, .site, .shop, .uk, .fr, .nl, .pl, .consulting, .cloud, .tech, .blog, .store, .online, and many more.

Via WHOIS

TLD	WHOIS Server
.de	whois.denic.de
.cn	whois.cnnic.cn
.fj	www.whois.fj
.gs	whois.nic.gs
.bayern	whois.nic.bayern
.cat	whois.nic.cat
.eus	whois.nic.eus
.radio	whois.nic.radio
.scot	whois.nic.scot
.sport	whois.nic.sport

How it works

Extracts the TLD from the domain name
Routes to the appropriate adapter (RDAP or WHOIS)
RDAP: HTTP lookup — 404 means available, 200 means registered
WHOIS: TCP port 43 lookup — pattern matching on the response
Returns a structured result with availability status
