einvoice-kit-mcp

MCP (Model Context Protocol) server that lets AI agents read and validate EU e-invoices locally: EN 16931, XRechnung, Factur-X/ZUGFeRD, UBL, CII, Peppol BIS.

{ "mcpServers": { "einvoice": { "command": "npx", "args": ["-y", "einvoice-kit-mcp"] } } }

Tools:

• validate_invoice — EN 16931 business-rule validation (~165 rules) with plain-language findings. Accepts XML content or a file path (.xml or Factur-X .pdf).
• read_invoice — parses any supported invoice into a summary plus structured data (parties, lines, VAT breakdown, totals, payment details).

Invoice data never leaves the machine. Zero dependencies beyond the MIT-licensed einvoice engine, which is tested against 120 official EU/KoSIT corpus files.
