How to Use the SimpleFatoora MCP in OpenAI Agents SDK

Q: What process does SimpleFatoora use for B2B invoicing when using the OpenAI Agents SDK?

For formal B2B billing, you call createvatinvoice. This tool ensures the document meets ZATCA standards. The agent will handle attaching the correct product and customer IDs to the final invoice record.

Q: What data does SimpleFatoora touch when validating API keys?

The validateapikey tool only handles your access token and confirms its active status. It doesn't touch customer or product data, just the credentials themselves.

Manage full customer lifecycles via the MCP Server.

When you need to manage client records, start by getting a list of existing users using `list_customers`. You can then fetch specific details for any account with `get_customer`, or update information like addresses using `update_customer`. If an account is closed, running `delete_customer` handles the removal process. These tools let your agent manage customer data across multiple steps. It's perfect for building a deployment where one specialized agent hands off tasks to another, ensuring client records are always current before invoicing.

Generate all required SimpleFatoora document types.

The system handles every type of tax document needed. You can run `create_vat_invoice` for formal B2B transactions or use `create_simplified_invoice` when dealing with direct consumer sales (B2C). Need to record a return? Call `create_credit_note`. The agent ensures the correct tool is invoked based on the transaction type. This makes sure your deployed product handles complex financial logic correctly. It covers standard purchases (`create_standard_purchase`) right through to simple goods tracking via `list_products`.

Verify data integrity and API access for the OpenAI Agents SDK.

Before any transaction, your agent must validate credentials using `validate_api_key`. This prevents failed runs due to expired tokens. For product management, you can check current stock levels or details with `list_products` or `get_product`. Remember that all document creations require a valid key. These verification tools provide the guardrails needed for production work. The agent always confirms connectivity using `check_simplefatoora_status` before attempting any data writes.

Setup guide

Set up SimpleFatoora 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 SimpleFatoora tools at runtime.
3

Create your Agent

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

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate SimpleFatoora 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="SimpleFatoora Agent",
            instructions="You have access to SimpleFatoora tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about SimpleFatoora MCP in OpenAI Agents SDK

You use the agent's tools to perform CRUD operations on customer accounts. To start, run `list_customers` to see who you have. Then, use `get_customer` to pull specific data before running `update_customer`. The agent handles all these steps for you.

For formal B2B billing, you call `create_vat_invoice`. This tool ensures the document meets ZATCA standards. The agent will handle attaching the correct product and customer IDs to the final invoice record.

Yes, the MCP Server supports multiple document creations. You can generate B2C invoices via `create_simplified_invoice`, or handle returns using `create_credit_note`. The agent determines which tool to call based on the required outcome.

Absolutely. Before making any purchase invoice, you should run `list_products` or check details with `get_product`. This verifies the necessary items exist in our system.

The `validate_api_key` tool only handles your access token and confirms its active status. It doesn't touch customer or product data, just the credentials themselves.
