How does the IBAN validation work?

The `validate_iban` tool performs a MOD-97 checksum. It rearranges the IBAN, converts letters to numbers, and verifies that the remainder of the division by 97 is 1.

Can I check the length requirements for a specific country?

Yes, you can use `get_validation_rules` to find the required character length for an IBAN in a specific country code.

What is the difference between IBAN and BIC?

IBAN identifies a specific bank account, while BIC (or SWIFT) identifies the specific bank. You can validate both using `validate_iban` and `validate_bic` respectively.

This MCP server provides precise validation for international banking identifiers. It uses the MOD-97 algorithm to confirm the mathematical accuracy of IBANs and enforces strict alphanumeric structural rules for BIC/SWIFT codes. Use validate_iban to check if an IBAN is valid, validate_bic to verify a BIC code, or get_validation_rules to retrieve expected IBAN lengths for specific countries.
