Quickstart

  "mcpServers": {
    "dncscrub": {
      "url": "https://mcp.dncscrub.com/mcp",
      "headers": {
        "x-dncscrub-api-key": "YOUR_LOGIN_ID"
      }
    }
  }
}
If your AI provider does not allow for custom headers, you can put the API key in the URL as a query parameter: 
{
  "mcpServers": {
    "dncscrub": {
      "url": "https://mcp.dncscrub.com/mcp?apiKey=YOUR_LOGIN_ID"
    }
  }
}
Your API key is your DNCScrub Login ID. Find it in the DNCScrub portal under Users → Get API Key. Your API key is your DNCScrub Login ID. Find it in the DNCScrub portal under Users → Get API Key.

Why Use This Server?

Modern LLMs are powerful—but they lack:
  • Knowledge of Federal & State DNC rules
  • Awareness of calling windows and holiday restrictions
  • Litigator detection
  • Reassigned number verification
  • Real-time campaign-specific policies
The DNCScrub MCP Server fills this gap.
This MCP server executes real API calls for compliance operations. For AI-assisted development and documentation search, see MCP for Developers.
