How do I use mcp-server-erechnung?

1. Click on "Deploy Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@mcp-server-erechnung Create an XRechnung for 3 hours of consulting at €120 to Stadt Köln" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

German E-Rechnung MCP Server (`mcp-server-erechnung`)

Official Model Context Protocol (MCP) server for German B2B & B2G E-Invoicing compliance (EN 16931 / Wachstumschancengesetz 2025–2027, KoSIT XRechnung 3.0.2, DATEV ZUGFeRD 2.5 / Factur-X PDF/A-3b, SEPA GiroCode QR, and Smart Hybrid Parsing).

Connect Claude Desktop, Claude Code, Cursor, Windsurf, Cline, or n8n AI Agents to deterministic German E-Rechnung generation, official KoSIT/veraPDF validation, and guarded Empfangspflicht parsing — with zero silent LLM hallucinations in tax or monetary fields.

Why Use This MCP Server?

100% Deterministic Financial Math (BigDecimal + ISO 13616 MOD-97): Your AI agent never generates raw XML and never computes final invoice math. Every qty * unitPriceNet, VAT bucket, and grossTotal is calculated deterministically in exact decimal arithmetic, and every Seller IBAN is verified via Modulo-97.
DATEV & KoSIT XRechnung 3.0 Compliant (BR-DE-* + veraPDF): Enforces German Business Rules (SellerContact, Leitweg-ID / BT-10, SEPA BG-16), embeds TrueType fonts + sRGB ICC profiles (ISO 19005-3 PDF/A-3b), and stamps scannable German GiroCode (EPC SEPA QR) payment codes.
Smart Developer DX: Automatically maps human units ("Stk", "Std", "Tage", "pauschal", "kg", "kWh") to UN/ECE Rec 20 codes (C62, HUR, DAY, LS, KGM, KWH) and auto-infers 0% VAT categories (AE § 13b Reverse Charge, K § 6a Intra-EU, E § 19 UStG, G Export) with mandatory BT-120 German exemption text.
100% Stateless & GDPR / DSGVO Safe: Zero invoice persistence or PII logging.

Tool Name	Description
`generate_erechnung`	Deterministically generate a `ZUGFeRD 2.5` `PDF/A-3b` (with visual DIN 5008 layout + GiroCode QR + `factur-x.xml`) or pure `XRechnung 3.0.2` XML from structured JSON (`<300ms`).
`validate_erechnung`	Validate any ZUGFeRD PDF or XRechnung XML against official EN 16931 XSD, KoSIT `XR_30` Schematron, and `veraPDF` (`rule_id`, `field`, `human_hint`).
`parse_erechnung`	Smart Hybrid Empfangspflicht parser: `~20ms` deterministic `NATIVE_XML` fast-path first, plus math-guarded legacy PDF extraction (`math_verified`, `iban_valid`, `discrepancy`).
`embed_zugferd_pdf`	Upgrade an existing visual PDF (Base64) + JSON into a true `PDF/A-3b` ZUGFeRD 2.5 hybrid document.
`magic_convert_pdf`	Convert a flat legacy PDF (Base64, max 5 pages) into ZUGFeRD 2.5 `PDF/A-3b` under strict `BigDecimal` & `MOD-97` guardrails.

B3.4/5.0

Scored 2026-11-13 07:30 across 5 tools

Disambiguation3/5

generate_erechnung, embed_zugferd_pdf, and magic_convert_pdf all ultimately produce a ZUGFeRD PDF/A-3b hybrid invoice, and the boundaries between 'generate from JSON', 'upgrade PDF+JSON', and 'convert flat PDF' are not fully crisp—magic_convert appears to combine parse+embed. validate_erechnung and parse_erechnung are clearly distinct, and the descriptions do help an agent pick the right entry point, but there is real overlap in the generation/conversion cluster.

Naming Consistency3/5

generate_/validate_/parse_erechnung follow a clean verb+domain pattern, but the set drifts to a different object name in embed_zugferd_pdf and a non-standard quirky verb in magic_convert_pdf. Readable but not one predictable convention across all five tools.

Tool Count4/5

Five tools is well within a healthy scope and each maps to a recognizable invoice operation (generate, validate, parse, embed, convert). Slight over-partitioning in the generation/embedding area keeps it from being a perfect fit, but nothing feels padded or missing count-wise.

Completeness4/5

The core lifecycle is covered: create both ZUGFeRD and XRechnung from JSON, validate against EN 16931/KoSIT/veraPDF, parse inbound invoices, embed and convert legacy PDFs. Minor gaps remain—no direct ZUGFeRD↔XRechnung format conversion and no preview/readable rendering—but agents can work around these via generate with the appropriate format flag.
