  2. 2Choose Create, name it TradingData, paste the MCP server URL and pick OAuth as the authentication method.
  3. 3Save. ChatGPT sends you to tradingdata.io to approve access. Enable the connector in a chat from the plus menu, or in Deep research sources.
  • In the API, pass an API key from your dashboard as the authorization value.

Python (Responses API)
from openai import OpenAI

client = OpenAI()
response = client.responses.create(
    model="gpt-5",
    tools=[{
        "type": "mcp",
        "server_label": "tradingdata",
        "server_url": "https://mcp.tradingdata.io",
        "authorization": "td_your_api_key",
        "require_approval": "never",
    }],
    input="Compare NVDA and AMD revenue growth over the last 4 quarters.",
)
print(response.output_text)

Replace td_your_api_key with a key from your dashboard (API keys). Each key can be revoked on its own.
