What is the IBAN Bank Validator MCP Server?
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.
Built-in capabilities (1)
Pass the full IBAN string and the engine performs the Modulus 97 checksum calculation to verify structural and mathematical validity. Validates international bank account numbers (IBAN) using mathematical Modulus 97 checksum

Frequently asked questions
Does it connect to banks?
No, it purely validates the mathematical checksum of the IBAN structure.
Is it secure?
Yes, 100% local evaluation. No data is transmitted.
What countries are supported?
All official SEPA and international countries that use the standard IBAN format.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
