What is the 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).
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.
How it works
- Append this tax-heavy integration logic
- Add your traditional basic auth API configuration bound in Private base64 streams directly on credentials config
- You are ready to process accounting loops using pure natural chatting formats
Who is this for?
- Regional Accounting Leads — Saving heavy hours navigating UI platforms trying to un-freeze single PDF bills.
- eCommerce Operators — Needing programmatic agents to check invoice status continuously in the background.

Frequently asked questions
Can I bulk cancel tax invoices directly on the Mexican IRS bypassing visual interfaces?
Yes. Utilize the cancel_invoice target tool carefully giving it the unique CFDI ID alongside the formal SAT motive parameter representing your reasoning, and it actively invalidates the fiscal stamp instantly at source.
How securely does the Basic Authentication hold within Vurb handling the Mexican invoices?
The variables act as deep protected MCP credentials. You input them once securely mapping directly to fields labeled with generic sensitive: true. They transform cleanly into masked Base64 encodings locally and disappear off visual UI radar guaranteeing no accidental token logging into public clouds.
Can I retrieve a raw representation like PDF base64 of an older CFDI directly via Claude text generation?
Absolutely. Deploy get_invoice_file referencing the exact entity ID while choosing between XML or PDF format outputs, granting heavy duty tracking across any calendar timeline seamlessly.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Facturama (SAT) MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
