  • audit_invoiceAudit e-invoiceread-only

    One-call audit for accounts payable: parse + validate (XSD, official EN 16931 / XRechnung rules, Kontor plausibility: totals recomputed, VAT rates, IBAN, Leitweg-ID check digits, dates, duplicates) and return header facts, VAT breakdown, verdict, grouped findings with fix hints and an accept / review / reject recommendation with rationale. Fully offline. Input: `file_path` (absolute, local filesystem only) or `content_base64` (required for chat attachments / sandboxed uploads).

  • check_obligationsCheck e-invoicing obligations (Germany)read-only

    Offline decision tree over the German e-invoicing mandate (§ 14 / § 27 Abs. 38 UStG, UStDV §§ 33/34/34a, E-RechV): what applies to an issuer or receiver (B2B / B2G / B2C), from when, transition rules (2026, 2027 with the €800,000 prior-year turnover threshold, 2028), exemptions (small business, small-amount invoices, exempt supplies, cross-border), accepted formats and whether a Leitweg-ID is needed. Every answer carries the primary sources, the date the legal parameters were last verified, and a non-advice disclaimer.

  • convert_invoiceConvert e-invoice

    Convert an invoice: extract the XML from a ZUGFeRD/Factur-X PDF, convert UBL ↔ CII via the EN 16931 semantic model (post-validated, with an honest loss report of anything that did not survive), or render a self-contained HTML preview to show the invoice to a human. Optional `output_path` writes the artifact (no overwrite unless `overwrite=true`). Fully offline. Input: `file_path` (absolute, local filesystem only) or `content_base64` (required for chat attachments / sandboxed uploads).

  • explain_ruleExplain validation ruleread-only

    Explain an EN 16931 / XRechnung rule id (e.g. BR-DE-15): official text, plain-language explanation (DE/EN), affected business terms, fix hint. Unknown ids get nearest-match suggestions.

  • generate_invoiceGenerate XRechnung / ZUGFeRD

    Create a compliant e-invoice from structured data: XRechnung 3.0 (UBL 2.1, default) or a ZUGFeRD 2.3 / Factur-X PDF/A-3 with embedded factur-x.xml (`target: zugferd-pdf`, profiles EN16931 / BASIC / EXTENDED). Amounts, VAT breakdown and totals are derived decimal-safe; the result is validated internally — for PDFs the XML is read back out of the generated file first (fail-honest: `valid` reports the real verdict, findings tell what is missing). Optional `output_path` writes the .xml / .pdf to the server's local filesystem (no overwrite unless `overwrite=true`). Fully offline.

  • list_capabilitiesList capabilitiesread-only

    Introspect this server: supported formats and profiles, bundled standard versions (XRechnung, EN 16931, KoSIT configuration, XSDs), rule knowledge-base stats, code lists, legal parameters' last-verified date, tools/resources/prompts and the sovereignty statement (offline, no persistence).

  • parse_invoiceParse e-invoiceread-only

    Detect the format (UBL/CII, EN 16931, XRechnung version, ZUGFeRD/Factur-X profile) of an XML or ZUGFeRD PDF invoice and return its EN 16931 semantic model (BT-annotated). Fully offline. Input: `file_path` (absolute, local filesystem only) or `content_base64` (required for chat attachments / sandboxed uploads).

  • validate_invoiceValidate e-invoiceread-only

    Validate an XML or ZUGFeRD PDF invoice against XML Schema and the official EN 16931 / XRechnung Schematron rules (KoSIT-equivalent verdict) plus Kontor plausibility checks, with plain-language explanations and fix hints. Fully offline. Input: `file_path` (absolute, local filesystem only) or `content_base64` (required for chat attachments / sandboxed uploads).
