How to Set Up and Use Domain Search
Domain Search MCP brings zero-configuration domain availability checking to AI assistants like Claude and ChatGPT, using a cascade of RDAP, GoDaddy, and WHOIS lookups to check domain status without requiring any API keys. It includes an AI-powered name suggestion engine (using a fine-tuned Qwen model locally), bulk checking for up to 100 domains, premium and auction domain detection, and price comparison across registrars. Founders, developers, and brand strategists use it to brainstorm and validate domain names directly inside their AI chat sessions.
Prerequisites
- Node.js 18 or later
- No API keys required for basic domain availability checks
- Optional: Porkbun or Namecheap API credentials for direct registrar pricing
- An MCP client such as Claude Desktop, Claude Code, or Cursor
Run via npx (zero install)
The server can be launched directly with npx — no global installation needed. This is the recommended approach for use with Claude Desktop.
npx -y domain-search-mcp@latestConfigure your MCP client
Add the server to your MCP client's configuration file. For Claude Desktop, edit claude_desktop_config.json. No API keys are required for basic operation.
Enable HTTP mode for web-based clients
For ChatGPT or browser-based MCP clients that require an HTTP endpoint instead of stdio, launch the server with the --http flag.
npx -y domain-search-mcp@latest --http
# Custom port:
MCP_PORT=8080 npx -y domain-search-mcp@latest --httpAdd optional registrar API keys
For real-time pricing from Porkbun or Namecheap, set their API credentials as environment variables. These are optional — basic availability checking works without them.
export PORKBUN_API_KEY=your_key
export PORKBUN_API_SECRET=your_secret
# or for Namecheap:
export NAMECHEAP_API_KEY=your_key
export NAMECHEAP_API_USER=your_username
export NAMECHEAP_CLIENT_IP=your_ipInstall from source for development
Clone the repository and build locally if you want to modify the server or run it without npx.
git clone https://github.com/dorukardahan/domain-search-mcp.git
cd domain-search-mcp
npm install && npm run build && npm startDomain Search Examples
Client configuration

}Prompts to try
Try these prompts in Claude Desktop or any connected AI client to research domain names.
- "Check if myproject.com, myproject.io, and myproject.dev are available."
- "Suggest brandable domain names for a coffee subscription startup."
- "Bulk check these 10 domain names and tell me which are available: [list]."
- "Find premium or auction domains related to 'fintech' that I could buy today."
- "Compare registrar prices for example.com across GoDaddy, Porkbun, and Namecheap."Troubleshooting Domain Search
Domain availability results seem inaccurate or outdated
The server uses a cascade: RDAP first, then GoDaddy API, then WHOIS. Results are cached with a configurable TTL. Clear the cache or set CACHE_TTL_DOMAIN=0 to force fresh lookups for every query.
AI domain suggestions are not returning results
The suggest_domains_smart tool uses a locally-run Qwen model — on first use it may take a moment to initialize. If you have a self-hosted inference endpoint, set QWEN_INFERENCE_ENDPOINT to point to it for faster responses.
HTTP mode server is not accessible from external clients
By default the HTTP server binds to 0.0.0.0 on port 3000. Check that MCP_HOST and MCP_PORT are set correctly, and that your firewall allows inbound connections on the configured port.
