What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

validate_einvoice
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 erro
peppol_lookup
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 invoice
check_leitweg_id
Check a German Leitweg-ID (buyer reference BT-10 for invoices to German public authorities) against the official format and check digit (spec v2.0.2), and whether the authority is registered on Peppol (peppol_registered). Returns validity, the parts and the expected check digits.
create_einvoice
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 b
read_invoice_pdf
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
explain_rule
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.

Common questions

Is Invoiceer e-invoicing tools safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.0) reached the registry 21 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?
