Chile Invoices (DTE boleta/factura electrónica via OpenFactura) MCP server

Void a Chile DTE by issuing a nota de crédito electrónica (TipoDTE 61) that references the original with CodRef=1 (anula documento) — this is the SII-correct way to cancel; there is no delete. Works through either backend (OpenFactura or LibreDTE, auto-selected from your credential header or the "provider" field). Pass the original document_type + folio; the credit note mirrors the original net amount and reverses it. Returns the credit-note folio.

Fetch a DTE you emitted (by document_type + folio) from your provider (OpenFactura or LibreDTE, auto-selected from your credential header or the "provider" field). Status values: ISSUED (accepted by the provider, awaiting/without an SII acceptance timestamp), ACCEPTED_BY_SII (SII reception confirmed). Returns the receptor, net/IVA/total (CLP). Safe to call anytime. (OpenFactura resolves your Emisor RUT from the API key; LibreDTE uses the x-libredte-emisor header.)

Issue a Chile electronic tax document (DTE): a boleta electrónica (consumer receipt, TipoDTE 39, default) or a factura electrónica (B2B invoice, TipoDTE 33), stamped against SII with the merchant's own CAF. Two backends (auto-selected from your credential header, or force with the "provider" field): OpenFactura/Haulmer (header x-openfactura-key; Emisor auto-derived from your account; DEV sandbox by default, x-openfactura-mode: production to go live) or LibreDTE cloud (header x-libredte-hash + x-libredte-emisor for your RUT; the certification-vs-production environment is whatever your emisor is registered as in LibreDTE — there is no server-side sandbox toggle). Both keep your SII certificate and CAF in your own provider account; this server only forwards a token and stores nothing. Amounts are in CLP (Chilean pesos: whole integers, no decimals). IMPORTANT price convention: for a boleta (39) each price is GROSS (IVA 19% already included, as shown to consumers); for a factura (33) each price is NET (IVA 19% is added on top).
