Hosted MCP server for expired, dropping, auction, backorder, and buy-now domains — powered by Karma.Domains. Search 400k+ daily listings with SEO metrics, Wayback history, and live domain checkers from Cursor, Claude, ChatGPT, and other MCP clients.

This repository is the catalog listing (README + server.json). The server itself runs at https://mcp.karma.domains/mcp.

Quick start

      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}
