🇨🇴 Colombia Invoice MCP live

AI agents can now issue a Colombia factura electrónica (factura de venta, DIAN UBL 2.1, modelo de validación previa). This remote MCP server wraps Matias API — a Software Propio provider that generates, digitally signs and transmits the invoice directly to the DIAN with no Proveedor Tecnológico (PT) middleman — with two tools: create_invoice and query_invoice. It only forwards the calls and does the local IVA math: signing and DIAN transmission stay inside your own Matias account.

Self-register free at matias-api.com — registration happens on the production URL and your credentials automatically replicate to the sandbox, so you can integrate against sandbox-api.matias-api.com/api/ubl2.1 before going live. Required header: x-matias-token (a JWT access_token or a Personal Access Token). Optional: x-matias-env (default sandbox), x-matias-base, and the owner-policy headers below. Your DIAN resolución and certificate live in your Matias account — this server never sees them.

How it works

• You describe, Matias signs & sends: create_invoice takes the buyer (NIT/name), line items, IVA rate and your DIAN resolution_number; the server does the local COP IVA math and posts the factura de venta to /invoice. Matias signs it and transmits it to the DIAN (validación previa), returning the cufe and state. It never signs here and stores nothing.
• Pesos are integer & tax-exclusive: COP is used as whole pesos — pass integer unit prices that are the valor neto (before IVA). IVA per line is 19 (standard), 5 (reduced) or 0 (exento/excluido); IVA is liquidated as net * rate/100 and the UBL totals assembled for you.
• Free to test: x-matias-env=sandbox (the default) builds/transmits in the pruebas environment with no fiscal effect; switch to production for real DIAN submission. Your account decides the DIAN resolución and certificate used.
• Status: query_invoice { uuid } returns the DIAN state, cufe and dian_message with numbered next_steps.

DIAN factura electrónica is mandatory (validación previa)

Colombia's DIAN factura electrónica de venta runs on the modelo de validación previa: the DIAN validates the document before it reaches the buyer, returning the CUFE that makes it fiscally valid. Under successive Resoluciones DIAN and the Estatuto Tributario, issuing the electronic factura de venta is obligatory for responsables de IVA and, progressively, for essentially all taxpayers selling goods or rendering services — paper and POS invoices are being phased out. With Matias you can integrate and test ahead of, or in step with, your obligation.

Why it is safe

• Stateless: no database — your Matias token travels per-request in a header and is never stored.
• Signing stays with you: the digital signature and DIAN transmission happen inside your Matias account (Software Propio, direct to DIAN, no PT); a compromise of this forwarder cannot forge or alter your invoices.
• 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 invoice grand total in pesos (COP).
