Mcp Einvoicing De
This server handles the full lifecycle of German electronic invoices in ZUGFeRD 2.x and XRechnung 3.x formats, both required for B2B invoicing in Germany starting 2025. It exposes six tools: create invoices in CII or UBL XML, validate against EN 16931 and KoSIT Schematron rules, parse existing invoice files, convert between ZUGFeRD profiles or to XRechnung, check Peppol participant registration via AS4, and query German VAT rules including reverse charge scenarios under §13b UStG. The validation catches BR-DE-* business rule violations specific to German requirements. Useful if you're building invoicing workflows for German companies or need to ensure compliance with the mandatory e-invoicing rollout.

EINVOICING_DE_KOSIT_ENABLESet to 1 to opt in to remote KoSIT cloud validation by default across all invoice_validate calls (egresses the full invoice payload). Local Schematron only by default; callers can still opt in per-call with cloud_validate=True.
EINVOICING_DE_KOSIT_VALIDATOR_URLURL of a self-hosted KoSIT validation tool REST endpoint (e.g. http://localhost:8080/api/v1/validate), used only when cloud validation is enabled (cloud_validate=True or EINVOICING_DE_KOSIT_ENABLE=1). Defaults to an [Unverified] validator.kosit.de endpoint if unset.
