How to Use the REST Countries MCP in OpenAI Agents SDK

Q: Does the REST Countries MCP server support currency lookups in OpenAI Agents SDK?

It does. Use getcountriesbycurrency to find which nations use a specific tender. The data returns in a format your agent can parse instantly.

Q: How do I query languages using REST Countries and OpenAI Agents SDK?

Simply trigger getcountriesbylanguage with your target string. The tool returns every country that lists that language as official.

Instant global lookups for your agents

Your agent needs accurate data to function. Use `get_all_countries` to feed your system a full list of sovereign states without manual input. This MCP Server provides the raw records directly to your logic. It's that simple.

Filter regional data with OpenAI Agents SDK

Stop guessing where a country sits on a map. Pass specific regions to `get_countries_by_region` to narrow down your agent's search space immediately. Your agent handles the response and moves to the next task. It keeps the context window clean.

Validate identity via country codes

Avoid ambiguity when your agent processes user input. The `get_country_by_code` tool resolves ISO alpha-2 or alpha-3 strings to full records. This ensures your agent works with verified data. It eliminates the risk of misidentification during complex logic chains.

Setup guide

Set up REST Countries 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 REST Countries tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())
