How to Use the Adyen MCP in OpenAI Agents SDK

Q: How do I connect the Adyen MCP Server to my OpenAI Agents SDK?

Install openai-agents and initialize MCPServerStreamableHttp pointing to your Vinkius Adyen endpoint. Pass the server instance inside the mcpservers list when creating your OpenAI Agents SDK agent.

Q: Does the OpenAI Agents SDK support caching for these Adyen MCP tools?

Absolutely. Set cacheToolsList=True in your OpenAI Agents SDK server parameters to stop your agent from fetching the Adyen schema on every single message. Doing so drastically reduces execution latency.

Q: How does the MCP Server handle multi-merchant environments in OpenAI Agents SDK?

Your OpenAI Agents SDK agent first runs listmerchants to identify the correct merchant ID for the user's region. Afterwards, it passes that ID into subsequent calls like getmerchantdetails to isolate Adyen operations.

Safe refunds with OpenAI Agents SDK guardrails

Your OpenAI Agents SDK setup triggers Adyen refunds using `refund_payment`, but moving money requires strict boundaries. By hooking this MCP Server up to your agent, you let it execute the refund only after validating the original 16-digit PSP reference against your system's guardrails. The OpenAI Agents SDK agent checks the transaction history, verifies the amount, and fires the Adyen refund without human intervention. Because OpenAI Agents SDK handles agent-to-agent handoffs, a triage agent can identify an Adyen refund request and pass it to a specialized payment agent with zero friction.

Automated regional discovery and account audits

Managing multiple global regions in Adyen usually means running `list_merchants` through your OpenAI Agents SDK agent to map your entire company profile across US and EU regions. This MCP Server lets your OpenAI Agents SDK agent scan active profiles and locate specific merchant IDs in seconds. Once your OpenAI Agents SDK agent gets the active accounts, it calls `get_merchant_details` to verify the technical configuration of each endpoint. You can track this entire discovery process directly in your OpenAI developer dashboard to ensure no unauthorized Adyen configurations slip through.

Deep payment metadata inspection

When an Adyen transaction fails, your OpenAI Agents SDK agent runs `get_payment_details` to inspect the complete technical authorization and capture metadata for any specific PSP reference. This tool retrieves raw transaction payloads instantly to diagnose payment bottlenecks. This gives your OpenAI Agents SDK agent the exact raw data needed to decide whether to trigger an Adyen refund or flag the account. Since you can cache the tool list using `cacheToolsList=True` in OpenAI Agents SDK, your production agents inspect payments with minimal latency.

Setup guide

Set up Adyen 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 Adyen tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about Adyen MCP in OpenAI Agents SDK

Install `openai-agents` and initialize `MCPServerStreamableHttp` pointing to your Vinkius Adyen endpoint. Pass the server instance inside the `mcp_servers` list when creating your OpenAI Agents SDK agent.

Yes, you configure this through the OpenAI Agents SDK guardrails by restricting exposure to tools like `refund_payment` at the agent definition level. Setting these boundaries prevents unauthorized financial operations.

Absolutely. Set `cacheToolsList=True` in your OpenAI Agents SDK server parameters to stop your agent from fetching the Adyen schema on every single message. Doing so drastically reduces execution latency.

Your OpenAI Agents SDK agent first runs `list_merchants` to identify the correct merchant ID for the user's region. Afterwards, it passes that ID into subsequent calls like `get_merchant_details` to isolate Adyen operations.

All Adyen PSP references and payment metadata pass through Vinkius's ephemeral V8 sandboxes directly to your OpenAI Agents SDK agent. No transaction amounts or merchant IDs are stored on our servers, keeping your OpenAI Agents SDK financial logs isolated.
