How to Use the Mastercard MCP in OpenAI Agents SDK

Q: Can my OpenAI Agents SDK agent perform a Mastercard binlookup?

Yes. You just call the binlookup tool with the first 6-8 digits of the card. The agent receives the issuer and card type data immediately.

Use the Mastercard MCP Server to verify card data and report fraud directly within your OpenAI Agents SDK production pipelines.

Real-time card validation for OpenAI Agents SDK

Stop passing invalid card data to your payment gateway. Use `validate_account` to check status before you trigger a transaction flow. Your agent gets an immediate response regarding account validity and issuer details, saving you from unnecessary processing costs.

Automated fraud reporting via OpenAI Agents SDK

Integrate `submit_fraud_report` to flag confirmed incidents instantly. This keeps your internal data synchronized with the Mastercard network. Your agent handles the report payload, ensuring you only send verified fraud cases to the database while keeping your logic contained.

Merchant data lookup with OpenAI Agents SDK

Fetch precise location information using `search_merchants` or `get_merchant`. Your agent identifies nearby payment points based on GPS coordinates. This gives your agent the ability to provide location-aware services that rely on actual merchant category classifications.

Setup guide

Set up Mastercard 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 Mastercard tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about Mastercard MCP in OpenAI Agents SDK

The server handles communication through your established endpoint token. Your agent never touches raw PANs unless it's passing them to the validation tool.

Yes. You just call the `bin_lookup` tool with the first 6-8 digits of the card. The agent receives the issuer and card type data immediately.

The server uses efficient HTTP streaming. Your agent triggers the tools as needed, keeping the overhead minimal for your production environment.

The data comes directly from official APIs. Your agent gets the exact address and category codes for any merchant found during the search.

We use ephemeral sessions for all requests. The server touches payment card numbers only for validation and reporting, never logging sensitive information to disk.
