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.

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

Connect to the MCP API in minutes

The MCP access uses Bearer tokens in the header and returns structured responses for controlled tool calls. You can find the token in your dashboard after login.

Header

Authorization: Bearer YOUR_API_TOKEN

Tools AI clients can call directly

validate_iban

Validates one IBAN, including SEPA bank participation.

validate_iban_batch

Validates multiple IBANs; each IBAN counts as one API request.

generate_test_iban

Generates an IBAN from country, bank code and account number.

ibantest_bank_account_validate

Checks a German bank code and account number.

ibantest_bic_validate

Validates a BIC.

get_usage_info

Shows API usage without consuming a validation request.

SEPA Direct Debit: Core and B2B

IBAN validation also returns the bank’s participation in SEPA Direct Debit schemes, checked against the EPC participant registers.

sddCore – SEPA Direct Debit Core; sddB2b – SEPA Direct Debit B2B.

Both schemes are checked independently. confirmed means there is an unambiguous, current register match. unknown means participation could not be confirmed; it does not mean the bank does not support the scheme.

This checks bank participation. It does not confirm account existence or direct debit eligibility, a mandate, or the success of a collection.

Frequently asked questions

What teams want to know before connecting MCP

Find more answers in our MCP FAQ about setup, authentication and API usage.

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 get_usage_info 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:

  • validate_iban – Validates one IBAN, including SEPA bank participation.
  • validate_iban_batch – Validates multiple IBANs; each IBAN counts as one API request.
  • generate_test_iban – Generates an IBAN from country, bank code and account number.
  • ibantest_bank_account_validate – Checks a German bank code and account number.
  • ibantest_bic_validate – Validates a BIC.
  • get_usage_info – Shows API usage without consuming a validation request.

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

SEPA Direct Debit: Core and B2B

IBAN validation also returns the bank’s participation in SEPA Direct Debit schemes, checked against the EPC participant registers.

sddCore – SEPA Direct Debit Core; sddB2b – SEPA Direct Debit B2B.

Both schemes are checked independently. confirmed means there is an unambiguous, current register match. unknown means participation could not be confirmed; it does not mean the bank does not support the scheme.

This checks bank participation. It does not confirm account existence or direct debit eligibility, a mandate, or the success of a collection.

Bank data validation

Bank directory checks for 40 countries

IBAN-Test goes beyond checksum-only validation. For these countries, we check the bank identifier against available bank directories and return bank details such as institution, city and BIC when available. See how IBAN validation works.

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.
