What is the Luhn CC Validator MCP Server?
LLMs cannot perform complex algorithmic validation like the Luhn check. This results in agents trying to process fake or mistyped credit card numbers, burning API limits and triggering anti-fraud systems. This MCP adds pure, zero-latency validation to the edge.
The Superpowers
- Pre-Flight Validation: Instantly block mathematically invalid credit card numbers before making costly Stripe/Adyen API calls.
- Brand Detection: Accurately identifies Visa, Mastercard, AMEX, and Discover purely based on mathematical prefixes.
Built-in capabilities (1)
Pass the card number string and receive validation status plus card brand detection (Visa, Mastercard, Amex). Validates credit card numbers using the mathematical Luhn algorithm and detects the card brand
