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 →

Tool Tokens
check_leitweg_id ~84

create_einvoice ~335

Create a valid e-invoice from structured data: XRechnung 3.0 (UBL or CII), ZUGFeRD / Factur-X PDF (EN 16931) or Peppol BIS Billing 3.0. The file is checked with the official KoSIT validator before it is returned; if it fails, you get the rule errors instead of a file. XML comes back as text in `xml`, the ZUGFeRD PDF as base64 in `pdf_base64`. XRechnung needs a seller contact (contact, phone, email), a buyer email or Peppol ID (electronic address), a buyer_reference (Leitweg-ID for German authorities) and payment details (iban). Peppol needs peppol_id for seller and buyer.

explain_rule ~105

Explain an e-invoice business rule code (EN 16931 BR-*, BR-CO-*, XRechnung BR-DE-*, Peppol PEPPOL-EN16931-*): official text (with an English translation for German-only rules), plain-language meaning, severity, the fields (BT/BG) involved and a link to the reference page.

peppol_lookup ~118

Check whether a company can receive e-invoices over Peppol. Accepts a Peppol ID (e.g. 0208:0123456749), a VAT number (e.g. BE0123456749, NL...B01) or a Belgian enterprise number. Returns each matching participant ID, whether it is registered, whether it accepts Peppol BIS invoices, and name/country from the Peppol Directory when published.

read_invoice_pdf ~179

Read an ordinary (non-e-invoice) PDF invoice and return its data in the input format of create_einvoice: seller and buyer (name, address, VAT ID, country), invoice number, dates, IBAN/BIC, Leitweg-ID and the invoice lines (only if quantity x price and the line sum match the PDF's net total; otherwise one line with the net total). Regex-based, no guessing: fields we can't read reliably are missing and listed in `missing`. Check and complete them, then call create_einvoice to get XRechnung, ZUGFeRD or Peppol. Scanned PDFs (no text layer) are not supported. Pass the PDF base64-encoded in `file_base64`. Max 5 MB.

NameTypeReqDescription
file_base64stringyesThe PDF invoice, base64-encoded.

No output schema declared.

No examples provided.

validate_einvoice ~161

Validate an e-invoice (XRechnung UBL/CII, ZUGFeRD / Factur-X PDF, Peppol BIS Billing 3.0, EN 16931) with the official KoSIT validator. Returns valid/invalid, the detected format, every error and warning with its rule code, and the exact corrected value for common calculation errors. Pass the XML as text in `xml`, or a PDF/XML file base64-encoded in `file_base64`. Max 5 MB.

NameTypeReqDescription
