Ibangen MCP Server

ibangen-mcp

Official MCP server for IBANgen, the IBAN generator and validator for payment testing.

MCP server that gives AI agents IBANgen tools for IBAN and US bank account test data.

For assistants without MCP, the same product map is published as plain text at https://ibangen.com/llms.txt and https://ibangen.com/llms-full.txt.

Generated IBANs are test data only. A valid IBAN does not prove that an account exists. US account numbers are synthetic; routing references do not establish live ACH, Fedwire or account eligibility. The metered US tools do not replace the free web preview and do not bypass bank metadata gates. They never automatically retry a transport failure, because a credit may already have been consumed.

Remote server (nothing to install)

Add https://ibangen.com/api/mcp as a custom connector in ChatGPT, Claude, Cursor or VS Code (Streamable HTTP, no key needed to start; send Authorization: Bearer <API key> for paid-plan limits). It offers validate_ibans, generate_test_ibans, bank_test_ibans (free sample IBANs, BIC and bank code of one bank), iban_format and calculate_iban.
