Validating an IBAN (International Bank Account Number) requires executing Modulus 97 arithmetic across a 34-character string. LLMs are incapable of performing this math, often guessing validity and causing failed international payouts in platforms like Wise or Stripe. This MCP brings strict banking validation to the edge.

The Superpowers

  • Modulus 97 Math: Performs exact mathematical checksum validation local.
  • Format Check: Verifies exact country-specific lengths and alphanumeric patterns before processing.
