Credit-card number validation MCP.
Part of Pipeworx — an MCP gateway connecting AI agents to 1394+ live data sources.
Tools
| Tool | Description |
|---|---|
validate_card |
Validate a credit/debit card number (keyless, offline): Luhn (mod-10) checksum, detected card network (Visa/Mastercard/Amex/Discover/JCB/Diners/UnionPay/Maestro), and whether the length is valid for that network. Spaces/dashes are ignored. NOTE: this checks the number is well-formed — it does NOT verify the card is real/active/funded (that needs a payment processor). |
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 1394+ 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.
