Italy Invoices (FatturaPA / SdI via Invoicetronic) MCP server

Issue an Italy B2B electronic invoice (fattura elettronica) in FatturaPA format (FPR12) and transmit it to the national SdI (Sistema di Interscambio) via Invoicetronic. Builds the FatturaPA XML (seller/buyer P.IVA + optional Codice Fiscale, address, line items, IVA breakdown) and uploads it under your own Invoicetronic API key. Bring your own credential as header x-invoicetronic-key — ik_test_ keys are free sandbox (no fiscal effect), ik_live_ keys transmit real invoices to the SdI (same base URL; the key prefix selects the environment). Italian IVA rates supported: 22 (ordinaria), 10, 5, 4 (ridotte). Amounts are in EUR. Transmission is asynchronous: this returns a send id — poll query_invoice with it to learn the SdI outcome (SENT / DELIVERED / REJECTED / NOT_DELIVERED). There is no cancel at the SdI level: to reverse an invoice you issue a credit note (nota di credito) as a new invoice.

Check the SdI processing status of an invoice sent by create_invoice, using its send id. FatturaPA transmission is asynchronous. Status values: SENT (Inviato — accepted by the SdI, not yet delivered to the recipient; poll again shortly); DELIVERED (Consegnato — delivered to the recipient, the invoice is fiscally complete); REJECTED (Scartato — the SdI rejected it for a validation error; fix the data and create_invoice again); NOT_DELIVERED (ImpossibilitaDiRecapito / MancataConsegna — the invoice is legally valid and available in the recipient's tax drawer, but could not be pushed to their receiving system); PROCESSING (no SdI notification yet — poll again shortly). Safe to call anytime.
