About Facturama (SAT) MCP Server
Connect your Facturama / SAT Mexico corporative tax backend to any LLM and natively automate all bureaucratic burdens surrounding digital fiscal receipts (CFDI 4.0).
Pydantic AI validates every Facturama (SAT) tool response against typed schemas, catching data inconsistencies at build time. Connect 14 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.
What you can do
- Live Ledger Invoice — Pull all your recently emitted or pending electronic invoices, checking official CFDI statuses tied into SAT.
- Catalog Maintenance — Retrieve detailed registered products directly, fully validated against official government usage codex.
- Invoice Emitting — Tell Claude to emit a real transaction legally charging a verified Mexican client containing correct RFC values.
- File Scraping — Re-download lost PDFs or massive XML nodes natively generated holding digital timestamps representing valid commerce.
The Facturama (SAT) MCP Server exposes 14 tools through the Vinkius. Connect it to Pydantic AI in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
