How to Use the Exchange Rates API MCP in OpenAI Agents SDK

Q: Can my OpenAI Agents SDK bot handle currency fluctuation using the Exchange Rates API?

Yes, use the getcurrencyfluctuationdata tool. It provides the delta between start and end dates so your agent can calculate volatility trends.

Integrate real-time currency data directly into your OpenAI Agents SDK workflows for accurate financial calculations.

Real-time currency conversion for agents

Your agent performs precise conversions between any two currencies. It uses `convert_currency_amount` to handle the math so you don't have to write custom logic for every transaction. This keeps your agent's decision-making loop tight. It avoids the lag of external manual checks by pulling current rates directly into your OpenAI Agents SDK runtime.

Automated market tracking in OpenAI Agents SDK

You get a birds-eye view of major markets by calling `get_top_market_rates`. It pulls the latest figures for USD, GBP, JPY, and CAD into your agent's memory space. Your agent can now react to market shifts instantly. It's the fastest way to feed raw financial data into your agent's reasoning process without manual data entry.

Historical data access for financial analysis

The `get_historical_exchange_rates` tool lets your agent look back at specific dates. It's useful for auditing past transactions or verifying rates from previous days. This MCP server provides the data your agent needs to build reliable reports. You can trust the numbers because they come straight from the source.

Setup guide

Set up Exchange Rates API 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 Exchange Rates API tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())
