How to Use the Mastercard MCP in Google ADK

Q: Is Mastercard data access restricted in my Google ADK agent?

You control which tools are exposed. Use the toolnames filter to limit your agent's access strictly to what it needs for the task.

Connect your Google ADK agents to Mastercard payment data for secure merchant lookups and industry-standard account verification.

Identify card details using Google ADK

Run `bin_lookup_post` to pull issuer bank and card type data. This helps your agent identify the product category before you define the user experience. It works by processing the card prefix through the secure POST method, ensuring your agent receives the necessary metadata without exposing full account numbers.

Map merchant locations with Google ADK

Use `search_places_by_address` to find nearby merchants based on user-provided strings. Your agent converts addresses into actionable payment location data. It returns details on digital wallet acceptance and contact info, letting your agent guide users to the right store.

Classify business types using Google ADK

Call `merchant_category_codes` to decode the industry type of any merchant. Your agent uses these 4-digit codes to filter or categorize spending. This provides a clear hierarchy for your industry analysis tasks, allowing the agent to differentiate between restaurants, retail, or travel services.

Setup guide

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

Common questions about Mastercard MCP in Google ADK

Yes. You pass the server parameters to the toolset and your agent gains access to all 12 tools immediately.

You can include any of the tools in your agent's toolset. The agent decides when to call `search_merchants` based on the user's intent.

You control which tools are exposed. Use the tool_names filter to limit your agent's access strictly to what it needs for the task.

The server is compatible with standard HTTP transports used by the framework. Your agent connects to the endpoint and starts executing calls.

The server treats cardholder names as volatile data. It processes the validation request and discards the sensitive fields immediately after the response is returned.
