How to Use the Facturama (SAT) MCP in OpenAI Agents SDK

Q: Can OpenAI Agents SDK handle CFDI cancellation with Facturama (SAT)?

Yes, your agent can call the cancelinvoice tool directly when a cancellation event triggers. It uses the UUID of the issued document to submit the cancellation request to the SAT portal.

Q: What happens if a client RFC is invalid?

Your agent catches the error during the createclient or getclient call. It stops the invoicing loop immediately to prevent submitting a bad payload to the SAT.

Validate Mexican tax data using OpenAI Agents SDK

The `get_tax_status` tool connects your Python agents directly to Mexico's tax authority to verify data compliance before you commit transactions. Your agent reads current rules and searches standard codes via `list_catalog` to ensure every line item matches legal requirements. By running these checks inside your agentic loops, you stop bad payloads before they hit the API. You configure this MCP server as an HTTP transport, and your agents automatically verify client profiles with `get_client` to prevent invalid submissions.

Automate CFDI 4.0 invoice generation safely

The `create_invoice` tool executes the entire CFDI generation process directly from your agent's reasoning loop. Your agent maps products using `list_products` and sets correct tax rules with `list_taxes` to build valid XML structures without human intervention. If a client changes their mind, the agent handles the rollback via `cancel_invoice` and cleans up database records with `delete_client`. This prevents the agent from executing stray actions, keeping your accounting books clean.

Extract and deliver tax files automatically

The `get_invoice_file` tool pulls the Base64 graphic representation of your CFDI invoices directly into your OpenAI Agents SDK runtime. Your agent decodes this file and calls `send_invoice_email` to deliver the PDF and XML files straight to the customer. You monitor this entire pipeline using the OpenAI dashboard to track tool calls. To audit sent items, the agent runs `list_invoices` and checks them against `list_clients` to ensure email addresses match official RFC records.

Setup guide

Set up Facturama (SAT) MCP in OpenAI Agents SDK

Prerequisites

Python 3.10+ installed
openai-agents package (pip install openai-agents)
Active Vinkius subscription with a valid endpoint token

1

Install the SDK

Run pip install openai-agents to install the OpenAI Agents SDK. The MCP integration is built-in — no extra dependencies needed.
2

Connect via SSE transport

Use MCPServerSse with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. The SDK auto-discovers all Facturama (SAT) tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives Facturama (SAT) tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Facturama (SAT) tools and returns structured results. Copy the full example on the right to get started.

agent.py

import asyncio
from agents import Agent, Runner
from agents.mcp import MCPServerSse

async def main():
    async with MCPServerSse(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ) as server:
        agent = Agent(
            name="Facturama (SAT) Agent",
            instructions="You have access to Facturama (SAT) tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about Facturama (SAT) MCP in OpenAI Agents SDK

Install the SDK with pip and initialize the HTTP server connection using the Vinkius endpoint. Pass the server instance directly to your agent constructor to auto-discover the 14 invoicing tools via this MCP connection.

Yes, your agent can call the `cancel_invoice` tool directly when a cancellation event triggers. It uses the UUID of the issued document to submit the cancellation request to the SAT portal.

You can set the caching parameter to true in your agent configuration to speed up tool discovery. This keeps the schema definition of tools like `list_products` and `list_taxes` in memory.

Your agent catches the error during the `create_client` or `get_client` call. It stops the invoicing loop immediately to prevent submitting a bad payload to the SAT.

All CFDI invoice details and RFC profiles pass through a secure, ephemeral V8 sandbox on this MCP host. No tax data or customer credentials are saved on Vinkius servers, ensuring compliance with local fiscal privacy laws.
