What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

• validate_invoice

  Check an XRechnung (UBL or CII XML) or a ZUGFeRD/Factur-X PDF against the official KoSIT rules. Returns the verdict, the rule set version, and every finding; each business-rule finding comes with a plain-language meaning, cause and fix. Send the XML as text in `xml`, the PDF base

• parse_invoice

  Read a received e-invoice — XRechnung or any EN 16931 invoice as UBL or CII XML, or a ZUGFeRD/Factur-X PDF — into structured data. `invoice` is in exactly the shape generate_invoice takes (fields the document lacks are left out); `stated` has the totals, the VAT breakdown and eac

• generate_invoice

  Produce an e-invoice as `ubl` or `cii` XML or a ZUGFeRD hybrid PDF (`zugferd`) from invoice data: an XRechnung for a public-sector buyer (profile `xrechnung`, the default), a plain EN 16931 invoice for a business (profile `en16931`). Totals are computed server-side in decimal ari

• explain_rule

  Explain one EN 16931 / XRechnung / Peppol business rule by its code (e.g. BR-DE-15, BR-CO-10, PEPPOL-EN16931-R010): what it requires, why invoices typically break it, and how to fix it, with a link to the full page. Case does not matter. Schema findings (cvc-*) have no explanatio
