Credit-card number validation MCP.

Part of Pipeworx — an MCP gateway connecting AI agents to 1133+ live data sources.

Tools

| Tool | Description | |------|-------------| | check_luhn | Run a raw Luhn (mod-10) check-digit validation on any numeric string (cards, IMEI, national IDs, etc.). Returns whether the check digit is valid and what the correct check digit would be. |

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "creditcard": {
      "url": "https://gateway.pipeworx.io/creditcard/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 1133+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about Creditcard data" })

The gateway picks the right tool and fills the arguments automatically.
