Validates international bank account numbers, BIC/SWIFT codes, EU and UK VAT IDs, and US EINs. Cross-checks country consistency and queries official registries to confirm supplier legitimacy before payment.

Example request: "Check if a supplier's IBAN and VAT number are valid before approving an invoice for payment"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Invoice & Payment ID Validator to help me. It is a free service with an MCP server at https://invoice-validator.mohamed-bahaa53000.workers.dev/demo/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- validate_iban: Validate an International Bank Account Number: mod-97 checksum, length for its country (100+ countries), SEPA membership. Returns the normalized and formatted IBAN, country and BBAN, or machine-readable error codes. Use before paying an invoice or saving supplier bank details.
- validate_bic: Validate a BIC/SWIFT code (8 or 11 chars): structure, ISO country, test-BIC flag. Pass the IBAN too and it checks that the BIC country matches the IBAN country (a common fraud/typo signal).
- validate_eu_vat: Validate an EU VAT ID (27 member states + XI): format and check digit offline. Set live=true to also query the EU VIES registry for registration status, company name and address (slower, may be throttled; failures return vies.checked=false, never a false 'invalid').
- validate_gb_vat: Validate a UK (GB) VAT registration number: format, branch/government/health-authority types, and the HMRC mod-97 / 9755 checksum.
- validate_ein: Validate a US Employer Identification Number: 9-digit format and a valid IRS campus prefix. EINs have no check digit, so this catches typos and fake prefixes, not every invalid number.
