IBAN-Test MCP Server

Use IBAN validation directly in AI tools and agents

Connect AI clients, internal agents and automations to IBAN-Test through the Model Context Protocol (MCP). Validate IBANs, generate IBANs, check BICs and query API usage - without building bank data logic into your AI system.

REST API Bearer Token MCP Endpoint

Why MCP?

Bank data validation where AI already works

AI agents can understand text, extract data from emails and prepare workflows. For valid payment data, they need a reliable tool. The IBAN-Test MCP server makes these checks available as structured tool calls.

Fewer manual checksAgents validate IBANs, BICs and account data directly in the workflow.
Fewer failed paymentsInvalid bank data is detected before it reaches ERP, CRM or checkout systems.
Clear tool responsesStructured results with code, message and details instead of free-form AI guesses.

For AI workflows that touch payment data

01Check invoice and document data

AI extracts IBANs from invoices and validates them before passing data to accounting or ERP.

02Onboarding and master data

Agents check bank details for suppliers, customers or users during data capture.

03Support and back-office automation

Support assistants can validate submitted bank details without implementing sensitive validation logic.

04Low-code and agent builders

MCP makes IBAN-Test available as a standardized tool for AI clients and automation platforms.

Integration

Frequently asked questions

What teams want to know before connecting MCP

Is the IBAN-Test MCP server a separate AI?
MCP provides validated IBAN, BIC and bank data tools for AI clients.

No. IBAN-Test does not provide a separate AI. It provides validated tools for AI clients and agents. The AI client calls these tools through MCP in a structured way.

IBAN, BIC and bank account results come from the IBAN-Test API, not from an AI guess. This matters when payment data is processed in emails, forms, workflows or back-office processes.

Does MCP use my API quota?
IBAN, BIC and bank account checks through MCP use API requests. Checking current usage is free.

Yes. When an AI client validates an IBAN, checks a BIC, validates a bank account or generates an IBAN through MCP, this uses one API request.

Checking your current usage with ibantest_api_usage does not use an API request. It only shows how much quota has already been used.

Which credentials do I need for MCP?
MCP access uses your API token as a Bearer token.

Use the same API token that you use for the REST API. Send the token as a Bearer token to the MCP endpoint.

https://www.iban-test.eu/mcp
Authorization: Bearer YOUR_API_TOKEN

You can find your API token in the dashboard after login.

Which MCP tools does IBAN-Test provide?
Validate IBANs, generate IBANs, validate bank accounts, validate BICs and check API usage.

The IBAN-Test MCP server provides structured tools for AI clients and agents:

  • ibantest_iban_validate - validate an IBAN
  • ibantest_iban_generate - generate an IBAN
  • ibantest_bank_account_validate - validate bank code and account number
  • ibantest_bic_validate - validate a BIC
  • ibantest_api_usage - show API usage

This lets an AI workflow validate payment data without implementing bank data logic itself.

Bank data validation

Validation against bank directories

For these countries, we check IBANs against available bank directories and return bank details such as institution, city and BIC when available.

IBAN syntax check

Format checks for 115 IBAN formats

Check IBANs for a valid structure, correct length and checksum. This helps you catch typos and transposed digits before a payment fails. Additional bank validation against real bank directories is available for the countries listed above.
