Colombia Invoices (DIAN factura electronica via Matias API) MCP server

Look up a previously-issued Colombia document by its uuid (the Matias document UUID returned by create_invoice) to read its DIAN state — wraps GET /documents/{uuid}. Returns the document metadata Matias holds: uuid, cufe (Código Único de Facturación Electrónica), state (the DIAN acceptance state), number, dian_message and created_at. Safe to call anytime; read-only. Required credential header (set once in your MCP client, per-request, never stored): x-matias-token (your Matias bearer token — a JWT access_token from POST /auth/login, or a long-lived Personal Access Token from POST /auth/token). Optional x-matias-env: sandbox (default = pruebas, no fiscal effect) | production (real DIAN fiscal effect). Optional x-matias-base overrides the production base URL Matias assigns on contract. Optional owner-policy headers x-agentpay-max-amount / x-agentpay-approval-above / x-agentpay-allowed-tools.

Issue a Colombia electronic invoice (factura de venta / factura electrónica, DIAN UBL 2.1) through Matias API, which digitally signs it and transmits it straight to the DIAN (no Proveedor Tecnológico middleman) from YOUR OWN Matias account — this server only forwards the call and never holds your certificate. It wraps POST /invoice. Amounts are in Colombian pesos (COP, integer convention) and unit prices are TAX-EXCLUSIVE (valor neto, before IVA). IVA (VAT) rate per line: 19 (standard), 5 (reduced), or 0 (exento/excluido); the server liquidates the IVA locally (line net * rate/100) and builds the UBL totals. You must pass your DIAN resolution_number (from the resolución de facturación DIAN issued to your account) and the buyer. On success you get back the DIAN cufe (Código Único de Facturación Electrónica) and the acceptance state. Set x-matias-env=sandbox (default) to build/transmit in the pruebas environment with NO fiscal effect. Required credential header (set once in your MCP client, per-request, never stored): x-matias-token (your Matias bearer token — a JWT access_token from POST /auth/login, or a long-lived Personal Access Token from POST /auth/token). Optional x-matias-env: sandbox (default = pruebas, no fiscal effect) | production (real DIAN fiscal effect). Optional x-matias-base overrides the production base URL Matias assigns on contract. Optional owner-policy headers x-agentpay-max-amount / x-agentpay-approval-above / x-agentpay-allowed-tools.
