Invoiceer e-invoicing tools's hosted MCP server (invoiceer.io), published by invoiceer.io; no sign-in required; Streamable HTTP; 6 tools.
No AI overview yet: these facts come from the registry entry and the server itself.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.invoiceer%2Feinvoicing/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}Validate an e-invoice
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.

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.
queryrequiredCheck a 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.
langleitweg_idrequiredCreate an e-invoice
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.

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.
file_base64requiredExplain a validation 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.
coderequired72% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

A hosted service is used under its provider's terms, so no license is expected here. This check is left out of the percentage.
