@validatefin/mcp

MCP server to validate SEPA, UBL/Peppol and camt.053 e-invoice / payment files — 100% locally, no data leaves your machine. Powered by ValidateFin.

Tools

• validate_sepa — SEPA Credit Transfer (pain.001)
• validate_ubl — UBL / Peppol BIS Billing 3.0 (EN 16931)
• validate_camt — camt.053 (ISO 20022) bank statement
• validate_iban — IBAN (mod-97 checksum, country & length)
• generate_camt_test — generate a camt.053 test statement from a pain.001 / pain.008 file

Validation tools take the file content as xml (a string) and return the result (valid/invalid, errors, summary) as JSON. validate_iban takes an iban string, and generate_camt_test returns the generated camt.053 XML.

Install

Add this to your MCP client configuration (Claude Desktop, Cursor, etc.):

{
  "mcpServers": {
    "validatefin": { "command": "npx", "args": ["-y", "@validatefin/mcp"] }
  }
}

Then ask your assistant to validate a SEPA, UBL/Peppol or camt.053 file.

Privacy

Validation runs entirely on your machine. No file or data is ever uploaded to a server — the same privacy guarantee as the ValidateFin website.
