🇦🇷 Argentina Invoice MCP live

AI agents can now issue Argentina electronic invoices — factura electrónica authorized at AFIP/ARCA, returning the CAE (Código de Autorización Electrónico) via WSFE. This remote MCP server wraps the Afip SDK with three tools: create_invoice, query_invoice, get_last_invoice_number. Factura A, B and C (monotributo) are supported.

}

Sign up free at app.afipsdk.com for an access_token (1000 requests/month). In dev mode no AFIP certificate is needed — the test CUIT 20409378472 works out of the box. Switch x-afip-mode to prod and pass your AFIP X.509 certificate + key per-request (afip_cert / afip_key) to authorize real invoices.

IVA computed for you

Send flat fields; the server builds the WSFE FECAESolicitar payload and computes the tax. Factura A/B discriminate IVA — line items are grouped by alícuota (0, 10.5, 21, 27%) into the AlicIva array with ImpNeto, ImpIVA, ImpTotal. Factura C (monotributo) does not discriminate IVA — ImpTotal = ImpNeto, ImpIVA = 0. The next invoice number is fetched automatically via FECompUltimoAutorizado.

Why it is safe

• Stateless: no database — the access_token travels per-request in a header and is never stored.
• Certificates never stored: in prod your AFIP X.509 cert + key are forwarded to Afip SDK for a single request and never logged or persisted.
• Certification stays upstream: the Afip SDK carries the AFIP/ARCA WSAA + WSFE certification; we only translate MCP calls and compute the IVA schema.
• Owner policy guardrails: x-agentpay-max-amount, x-agentpay-approval-above, x-agentpay-allowed-tools — set by the human owner in client config; the agent cannot relax them.

Weak-model friendly

Invoice type, IVA rates, doc types and CUIT validated with teaching errors; the IVA discrimination and all totals are computed automatically; the next invoice number is fetched for you; every result embeds numbered next_steps (including: Argentina has no WSFE cancel — reverse with a nota de crédito).
