Domain-MCP

A simple MCP server that lets AI assistants help you with domain research - checking availability, looking up WHOIS info, finding expired domains, and more.

No API keys needed. Everything works out of the box.

What it does

• Check domain availability - See if a domain is available to register

• WHOIS lookup - Get registration info, expiration dates, registrar details

• DNS records - Look up A, MX, TXT, and other DNS records

• SSL certificates - Check SSL cert info and expiration

• Find expired domains - Search for recently expired or deleted domains

• Domain age - See how old a domain is

• Bulk checks - Check multiple domains at once

Using with Claude Desktop

Add this to your Claude Desktop config:

{
  "mcp-servers": {
    "domain-mcp": {
      "command": "python",
      "args": ["/path/to/domain-mcp/main.py", "--transport", "stdio"]
    }
  }
}

Example Usage

Just ask Claude things like:

• "Is mydomain.com available?"

• "Show me WHOIS info for google.com"

• "Find expired domains with 'tech' in the name"

• "What are the DNS records for example.com?"

How it works

Uses free, public APIs and services:

• RDAP for WHOIS data (no auth needed)

• Cloudflare DNS over HTTPS

• crt.sh for SSL certificates

• Public domain databases

Everything is fetched fresh when you ask - no caching, always current data.
