How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →

Supply Chain Security99
  • No malware found by supply-chain analysis.Pass
  • No known CVEs affecting this package version or its production dependencies.Pass
  • Runs hatchling.build at install time, a recognised native-build step with no shell scripting around it. View diagnostics → Pass
  • 3 of 37 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency48
  • Source repository is publicly reachable at the declared URL. View diagnostics → Pass
  • Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail

MCP tools · 50 exposed · ~4,293 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

invoice_convert ~219

Convert a ZUGFeRD or XRechnung invoice to a different profile or syntax. Supports ZUGFeRD profile upgrades and downgrades, ZUGFeRD <-> XRechnung conversion, and cross-syntax CII <-> UBL transformation. Profile downgrades may result in data loss; set allow_data_loss=True to permit this.

NameTypeReqDescription
allow_data_lossbooleanIf True, allow profile downgrades that discard data. Discarded fields are listed in the output. If False and data loss would occur, the conversion is rejected.
target_profilestringyesOne of: MINIMUM, BASIC_WL, BASIC, EN_16931, EXTENDED, XRECHNUNG.
target_syntaxstringTarget syntax: 'CII' or 'UBL'. UBL is only valid for XRECHNUNG.

Structured output declared, but exposes no named fields.

No examples provided.

invoice_create ~426

Generate a ZUGFeRD 2.x or XRechnung 3.x invoice in XML (CII or UBL) format. Supports all ZUGFeRD profiles: MINIMUM, BASIC_WL, BASIC, EN_16931, EXTENDED. For XRechnung, set profile to XRECHNUNG and choose CII or UBL syntax. When the buyer is a German VAT-registered business (DE-prefixed VAT id), the Wachstumschancengesetz B2B mandate (effective 2025-01-01, §14 Abs. 2 UStG) requires a structured EN 16931 invoice. Non-XML output is rejected unless transitional_period_opt_in is set to True (allowed only 2025-2026 with the buyer's written consent).

Structured output declared, but exposes no named fields.

No examples provided.

invoice_parse ~154

Extract structured data from a ZUGFeRD 2.x or XRechnung 3.x invoice. Accepts raw XML (CII or UBL), base64-encoded XML, or base64-encoded PDF (ZUGFeRD hybrid — the XML is extracted from the PDF/A-3 attachment). Returns a structured JSON object matching the invoice data model.

NameTypeReqDescription
include_raw_xmlbooleanInclude the raw XML string in the response.
pdf_base64Base64-encoded PDF bytes. The tool will extract the embedded XML attachment (ZUGFeRD hybrid PDF/A-3).

xml_contentRaw XML string.

Structured output declared, but exposes no named fields.

No examples provided.

invoice_validate ~427

Validate a ZUGFeRD 2.x or XRechnung 3.x invoice XML. Checks against EN 16931 rules and German KoSIT Schematron rules (BR-DE-* business rules). Returns a structured validation report with errors and warnings. Supports all ZUGFeRD profiles (MINIMUM through EXTENDED) and XRechnung (CII and UBL syntax). Profile and syntax are auto-detected if not specified. By default this validator runs entirely locally (Schematron only). Set cloud_validate=True (or EINVOICING_DE_KOSIT_ENABLE=1) to opt in to sending the invoice XML to a remote KoSIT endpoint. Doing so egresses the full invoice payload.

NameTypeReqDescription
cloud_validatebooleanOpt in to sending the invoice XML to a remote KoSIT endpoint (egresses the full invoice payload). Local Schematron only by default.
kosit_strictbooleanIf True, fail hard when the KoSIT cloud validator is unreachable instead of falling back to local Schematron.
profileOverride profile detection. One of: MINIMUM, BASIC_WL, BASIC, EN_16931, EXTENDED, XRECHNUNG. If omitted, auto-detected from the XML GuidelineID.
strictbooleanIf True, warnings are also reported. If False, only errors are returned.
syntaxOverride syntax detection. One of: CII, UBL. If omitted, auto-detected from the XML root element namespace.
use_local_only[Deprecated] Use cloud_validate instead. use_local_only=True is equivalent to cloud_validate=False, which is now the default; this alias is retained for one release and will be removed.
xml_base64Base64-encoded XML bytes of the invoice.
xml_contentRaw XML string of the invoice to validate. Provide either xml_content or xml_base64, not both.
