How to Use the Nuvei MCP in Google ADK

Q: How do I connect the Google ADK to the Nuvei MCP Server?

You initialize McpToolset with the MCP Server HTTP parameters. Then, pass the toolset into your LlmAgent constructor to expose tools like createpayment to Gemini.

Q: Can I restrict which Nuvei tools are exposed to the Google ADK?

Yes, you can use the optional toolnames filter in the toolset configuration. This lets you restrict the Google ADK to read-only tools like getpayment while blocking write actions.

Q: Where is my sensitive cardholder data processed during tokenization?

All card details processed via createcardtoken are sent directly to Nuvei's secure endpoints over encrypted channels. The Google ADK never stores raw card numbers, and the Vinkius sandbox ensures no payment data leaks into your Vertex AI logs.

Connect Google ADK and Gemini to Nuvei to analyze transaction history and run payments directly from BigQuery data.

Analyze Nuvei transaction data with Google ADK

Let Gemini analyze months of payment history using its massive context window. By calling `get_transactions` through the Google ADK, your agent pulls thousands of records directly into its context window to spot fraud trends or reconciliation discrepancies. You can combine this payment data with your warehouse. The agent pulls transaction records from this MCP Server, correlates them with customer tables in BigQuery, and highlights mismatched records instantly.

Trigger charges directly from your Google Cloud workflows

Move from analysis to action. Your enterprise agent can invoke `create_payment` to charge customers based on usage metrics processed in BigQuery. The Google ADK handles the tool execution, returning the transaction ID to your pipeline. For physical shipments or delayed billing, the agent uses `capture_payment` to capture funds once your warehouse systems confirm dispatch. If a pipeline errors out, the agent can call `void_payment` to cancel the pending authorization.

Manage payment tokens using Gemini and Google ADK

Securely register customer cards without manual data entry. The agent takes raw card details from your secure inputs and runs `create_card_token` to generate a reusable token. The agent manages these payment tokens over time. Using `update_token` and `get_token`, your Google ADK agent keeps customer records accurate, while `delete_token` handles immediate subscription cancellations.

Setup guide

Set up Nuvei 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 Nuvei 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="Nuvei_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Nuvei tools via MCP.",
    tools=mcp_tools,
)

You initialize `McpToolset` with the MCP Server HTTP parameters. Then, pass the toolset into your `LlmAgent` constructor to expose tools like `create_payment` to Gemini.

Yes, you can use the optional `tool_names` filter in the toolset configuration. This lets you restrict the Google ADK to read-only tools like `get_payment` while blocking write actions.

Gemini's million-token context window lets the agent ingest huge transaction lists from `get_transactions`. The Google ADK passes this raw data directly to the model for deep analytical tasks.

Yes, this server supports both configurations. You can run it as a local Stdio process during development or host it via HTTP for production Google ADK deployments.

All card details processed via `create_card_token` are sent directly to Nuvei's secure endpoints over encrypted channels. The Google ADK never stores raw card numbers, and the Vinkius sandbox ensures no payment data leaks into your Vertex AI logs.
