Connecting to Chat GPT
Use ChatGPT to manage your brokerage account through a custom MCP app.
Light Horse connects to ChatGPT through the Model Context Protocol (MCP). Once set up, you can manage your brokerage account, check positions, and place trades directly from ChatGPT.
Create the Plugin
Go to Plugins on sidebar and click a Plus sign to add a new plugin. On the form you can enter the following:
- Name: anything you like, for example Light Horse
- Connection:
https://portal.lighthorse.io/mcp - Authentication: OAuth
Set the checkbox to agree with OpenAI disclaimer and click Create to save the new plugin. ChatGPT will open a browser window with Light Horse login window. Login as usual, and on the next screen authorize Chat GPT to access your Light Horse account. If your browser is already authenticated at Light Horse, it will automatically redirect so that you don't even see the login window.
Start Trading
Once connected, ask ChatGPT anything about your account. For example:
- "Deposit a $1000 and invest it to SPY please."
- "How is my Light Horse portfolio doing today?"
- "Place a limit order for 10 shares of AAPL at $200."
- "Show me my latest tax form."
