🇩🇴 Dominican Republic Invoice MCP live

AI agents can now submit a Dominican Republic e-CF (factura electrónica / comprobante fiscal electrónico) to the DGII. This remote MCP server forwards your already-signed e-CF XML to the government DGII gateway — get_seed → get_token → submit_invoice (returns a trackId) → query_status. It only wraps the DGII web services: your DGII digital certificate and the e-CF signing stay merchant-side, and this server does not generate the e-CF XML.

Omit x-dgii-env to stay in the open test (TesteCF certificación) environment — no fiscal effect, no registration; prod = eCF production. DGII authentication is certificate-based: you sign the semilla and every e-CF with your own DGII-recognized digital certificate (Digifirma or another approved CA). Your certificate and private key never leave your side — this server never sees them.

How it works

• Certificate-based auth (4 steps): get_seed fetches a semilla → you sign it merchant-side → get_token exchanges the signed semilla for a ~1h Bearer token → you build + sign your e-CF → submit_invoice forwards it and returns a trackId.
• You sign, we forward: you pass the signed semilla and signed e-CF as base64; this server never signs, never generates the XML, and never stores anything.
• Asynchronous validation: a trackId is your acuse de recibo (receipt) — query_status polls /ConsultaResultado until estado is Aceptado (fiscally valid), Aceptado Condicional, or Rechazado.
• Status enums: results carry estado, codigo, rnc, encf, mensajes[] and numbered next_steps.

Why it is safe

• Stateless: no database — your signed XML and session token travel per-request and are never stored.
• Signing stays with you: the digital signature and the DGII certificate are applied and kept merchant-side; a compromise here cannot forge or alter your e-CF.
• 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. The cap applies to the grand total (MontoTotal, incl. ITBIS, in pesos DOP) when it can be read from the signed XML.

Weak-model friendly

Environment taken from a header (never in the body); the four DGII web services mapped one-to-one to four tools; status enums spelled out in every tool description; DGII HTTP responses passed through with numbered next_steps; every error teaches the fix (sign the semilla, base64 not raw XML, missing token, env). get_seed has no fiscal effect.
