Real-time market data in your OpenAI Agents SDK

Your agent pulls live prices and orderbooks without leaving the Python runtime. Use `get_latest_quotes` or `get_latest_orderbooks` to feed current market state into your agent's decision loop. The OpenAI Agents SDK automatically maps these functions to your tool definitions. It handles the transport so your logic stays focused on the trading strategy.

Historical OHLCV analysis for agent backtesting

Feed candle data into your agent models using `get_ohlcv`. This lets your system analyze price action across specific timeframes directly from the data source. Since you are using the OpenAI Agents SDK, these calls benefit from full tracing. You can verify exactly what data your agent requested before it makes a trade decision.

Asset and exchange discovery

Map available markets dynamically using `list_assets` and `list_exchanges`. Your agent can now identify which trading pairs exist before attempting to fetch deep market data. This MCP server ensures your agent doesn't hallucinate symbols. If it isn't in the CoinAPI registry, the agent knows immediately.

Setup guide

Set up CoinAPI 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 CoinAPI tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about CoinAPI MCP in OpenAI Agents SDK

You instantiate an MCPServerStreamableHttp object with your endpoint. Pass that into your Agent constructor as part of the mcp_servers list. The SDK handles the rest.

Yes, you should set cacheToolsList to True in your config. This prevents unnecessary round-trips and keeps your agent within the allowed request volume.

The SDK provides internal guardrails for tool execution. You define the constraints in your agent setup to ensure the data returned is safe to process.

Vinkius manages your connection securely. Your credentials never touch the agent code itself, keeping your access keys out of your local environment.

Your market data requests are ephemeral. They exist only for the duration of the agent's memory window and are never logged or stored by the host.
