How it works

1

Connect once

Add CatchDoms to your MCP client config. Takes 30 seconds. Your API key handles authentication.

2

Ask questions

Talk to your AI normally. "Show me .de domains with DA above 30" or "What auctions end today?"

3

Get results

Your AI fetches the data, formats it, and can help you analyze or export it.

MCP Server for AI Assistants

Connect CatchDoms directly to Claude Code, Cursor, or any MCP-compatible AI assistant.

What is MCP?

Model Context Protocol (MCP) is an open standard that lets AI assistants securely connect to external data sources. Instead of making API calls manually, you can ask your AI assistant natural language questions like "find .fr domains older than 10 years with backlinks".

Setup

  1. Get your API key from the API dashboard
  2. Add this configuration to your MCP client

Claude Code / Cursor

{
  "mcpServers": {
    "catchdoms": {
      "type": "http",
      "url": "https://catchdoms.com/mcp/catchdoms",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Claude Desktop

{
  "mcpServers": {
    "catchdoms": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://catchdoms.com/mcp/catchdoms",
        "--header",
        "Authorization: Bearer YOUR_API_KEY"
      ]
    }
  }
}

Requires Node.js installed.

Where to put this?

Claude Code: ~/.claude.json. Cursor: Settings > MCP. Other clients: check their docs for MCP server config.

Questions

How is this different from the REST API?

Same data, different interface. The REST API is for code: you make HTTP requests, parse JSON. MCP is for conversation: you ask your AI, it handles the technical bits. Both use your API key, both count toward rate limits.

Which MCP client should I use?

Claude Code if you work in terminal. Cursor if you prefer a full IDE. Both support MCP servers out of the box. Any client that implements the MCP spec will work.

What are the rate limits?

Same cap as the REST API — Pro is 15 requests per minute, Authority is 60 requests per minute. Each AI tool call counts as one request, so if your assistant runs 5 searches in a conversation, that is 5 requests against your bucket.

Is my API key safe?

Your key stays in your local config file. It's sent via HTTPS headers. We never see it in logs. Revoke it anytime from the API dashboard.
