How to Use the Airwallex MCP in OpenAI Agents SDK

Q: How is my Airwallex balance and transaction data kept secure?

Your financial data, including balances fetched via getbalance, runs inside an isolated V8 sandbox on Vinkius. The connection uses ephemeral execution, meaning your sensitive financial figures are never stored or logged on our servers after the agent finishes its call.

Let your OpenAI Agents SDK inspect Airwallex balances and route global payments safely with built-in guardrails.

Secure Airwallex balances in OpenAI Agents SDK

Connect your OpenAI Agents SDK to the Airwallex MCP Server to check treasury balances across global accounts. This lets your python agents inspect cash flow using `get_balance` and `list_accounts` before they decide to spin up a transfer or flag a low-balance alert. The SDK handles the heavy lifting, passing these tools directly to your agent's execution loop. If an agent tries to pull balance data, the built-in guardrails ensure it only accesses the specific accounts you authorized in your Vinkius dashboard.

Confirm global payments before agent execution

Running autonomous financial workflows can make anyone nervous. By exposing `list_payments` and `list_transfers` to your agents via our MCP Server, you give them the visibility they need to confirm past transactions before creating new ones. The SDK traces every single call to these tools on your OpenAI dashboard. You see exactly when an agent checked a payment status, preventing duplicate transfers and giving you a clean audit log of all financial decisions.

Compare live FX rates for smart routing

Let your agents query live conversion rates with `get_fx_rates` to optimize multi-currency payouts. Instead of hardcoding exchange rules, your agent checks the real-time market and picks the best window to move funds. Your agent calls `list_beneficiaries` to match the target account with the optimal currency. The OpenAI framework manages these tool handoffs, letting a specialized FX agent pass the transaction details to a payment agent with zero manual intervention.

Setup guide

Set up Airwallex 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 Airwallex tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about Airwallex MCP in OpenAI Agents SDK

You pass the Vinkius MCP server link to the Agent constructor using the streamable HTTP parameters. The SDK auto-discovers tools like `get_balance` and `get_fx_rates` instantly. Setting the cache flag keeps your agent fast by avoiding redundant schema fetches.

Yes, you control tool access directly in your Vinkius dashboard. This MCP setup lets you expose only `list_accounts` and block any tools that modify funds if you want a read-only agent.

Guardrails act as a runtime shield before any tool execution. When an agent attempts to call `get_balance`, the SDK checks the parameters against your safety constraints, preventing the agent from passing malformed account IDs.

No, Vinkius handles the authentication handshake for you. Your OpenAI Agents SDK only needs a single Vinkius MCP connection token, keeping your sensitive financial credentials completely out of your codebase.

Your financial data, including balances fetched via `get_balance`, runs inside an isolated V8 sandbox on Vinkius. The connection uses ephemeral execution, meaning your sensitive financial figures are never stored or logged on our servers after the agent finishes its call.
