How to Use the UnionPay Open Platform MCP in Google ADK

Q: When building with UnionPay Open Platform and Google ADK, how does the system handle tokenization?

Your agent uses requestcardtoken to securely tokenize card information. This process ensures that even if data is stored in BigQuery, you are only working with secure, non-raw tokens.

Q: Can Google ADK handle both KYC and payment cancellation using UnionPay Open Platform?

Yes. You can run verifycardkyc to confirm identity, and if necessary later, the agent uses cancelcardtoken to revoke access rights.

Q: Regarding data privacy when using UnionPay Open Platform with Google ADK, what specific data types are touched?

This server touches card tokens. Using requestcardtoken, you manage the creation and lifecycle of these secure payment identifiers, keeping raw card data out of your agent's immediate scope.

Execute Secure Payments via MCP Server

Your LlmAgent can start an online checkout session by calling `init_secure_payment`. This action sets up a secure payment flow for UnionPay, which is critical when dealing with large-scale enterprise transactions. After the initial setup, you'll use the agent to manage the full transaction lifecycle. You can also run `request_card_token` to securely store card information within your Google Cloud environment.

Monitor Transactions and Card Status in Google ADK

Need visibility into payments? The agent queries `get_qr_transaction_status` to check if a QR transaction completed successfully. Similarly, using `check_card_risk_status` lets you assess risk before committing funds. These tools allow your Gemini-powered agents to make data-driven decisions in real time.

Manage User Identity and Payment Tokens with MCP Server

You can onboard users by calling `verify_card_kyc` to verify their identity against UnionPay standards. It’s also important for compliance that your agent knows how to stop old access; call `cancel_card_token` when a token is no longer needed. These capabilities let you build full, end-to-end payment pipelines directly in BigQuery and Vertex AI.

Setup guide

Set up UnionPay Open Platform MCP in Google ADK

Prerequisites

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

1

Install Google ADK

Run pip install google-adk to install the Agent Development Kit. MCP support is included via the McpToolset class.
2

Connect via SSE transport

Use McpToolset.from_server() with SseServerParams pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create an LlmAgent

Pass the returned mcp_tools list directly to LlmAgent(tools=mcp_tools). The ADK maps each MCP tool to a native Gemini function call — no manual schema definitions required.
4

Run with any Gemini model

The agent works with any Gemini model (gemini-2.0-flash, gemini-2.5-pro, etc.). Copy the full example on the right to get started with UnionPay Open Platform tools in your ADK agent.

agent.py

from google.adk.agents import LlmAgent
from google.adk.tools.mcp_tool.mcp_toolset import McpToolset
from google.adk.tools.mcp_tool.mcp_session_manager import SseServerParams

# Connect to the MCP via SSE
mcp_tools, exit_stack = await McpToolset.from_server(
    connection_params=SseServerParams(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    )
)

# Create your agent with auto-discovered tools
agent = LlmAgent(
    name="UnionPay Open Platform_agent",
    model="gemini-2.0-flash",
    instruction="You have access to UnionPay Open Platform tools via MCP.",
    tools=mcp_tools,
)
