Einvoicing De MCP Server

MCP server (Model Context Protocol) in Python for German electronic invoicing in ZUGFeRD 2.x and XRechnung 3.x formats (EN 16931, FeRD, KoSIT). Enables AI agents (Claude, IDEs) to create, validate, parse, and convert e-invoices that are fully compliant with the German B2B e-invoicing mandate (effective from 2025, phased enforcement through 2027 to 2028) and the European standard EN 16931. Its 15 documented tools cover peppol, invoice, report, mls.

People who work with peppol, invoice and report and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in XSLT.

03 · What Einvoicing De can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can validate an invoice against EN 16931 and KoSIT rules (BR-DE-\). Local Schematron validation runs by default (no data leaves your machine), extract structured data from ZUGFeRD or XRechnung XML, or from a PDF/A-3 hybrid invoice with embedded factur-x.xml / zugferd-invoice.xml, check whether a business is registered on the Peppol network, and fetch the AS4 endpoint for a participant's document type.
