Manage Client Accounts via MCP Server

Your agent can find all registered customers using `list_clients`, or pull a specific person's financial standing with `get_client`. This lets your system immediately check if a client has an overdue balance before processing an order. Need to add new business partners? Just call `create_client` and register them instantly. You also have the option to fetch deep insights into sales totals using `list_sales`, giving you a quick view of where the revenue is coming from.

Control Inventory Levels with Treinta App

Inventory management runs smoothly when your agent calls `list_products` to see everything in stock. If an item sells out, it's simple: use `update_product_stock` to adjust the physical quantity right away. This prevents overselling and keeps the store data accurate. Beyond checking stock, you can add brand new merchandise by calling `create_product`. Your agent ensures every SKU has a place in the system before sales even start.

Process Transactions & Stats with OpenAI Agents SDK

The core financial loop is covered here. An agent can create a new sale using `create_transaction`, or it can clean up messes by reversing bad entries with `delete_transaction`. You'll never lose track of cash flow again. Want to see the big picture? Run `get_business_stats` for macro P&L operations. Need a list of every recorded financial movement? Use `list_transactions`.

Setup guide

Set up Treinta App 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 Treinta App tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())
