Process Secure Pay Checkouts via MCP Server

Your OpenAI Agent can initiate an online payment session using `init_secure_payment`. This handles the entire checkout setup for UnionPay. It ensures that your deployed product correctly processes payments by establishing a secure connection first. After initialization, you can use `request_card_token` to tokenize the user's card data. This action saves the payment method safely for future transactions without ever storing raw credentials.

Manage Payment Status and Risk Checks with OpenAI Agents SDK

Need to know if a QR code transaction went through? Call `get_qr_transaction_status` to check the payment status instantly. You can also run `check_card_risk_status` before processing anything, giving you immediate visibility into UnionPay's risk assessment for that card. This gives your agent crucial guardrails. It prevents transactions from starting if the card is flagged or if the status isn't clear.

Verify Identity and Cancel Tokens with MCP Server

Before accepting payments, run `verify_card_kyc` to check a user’s identity and bind the card. This crucial step validates both the person and the payment instrument within UnionPay. Furthermore, if a subscription ends or a token is compromised, your agent can call `cancel_card_token`. This unbinds an existing token immediately, protecting the customer's account.

Setup guide

Set up UnionPay Open Platform 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 UnionPay Open Platform tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())
