Public.com just made it possible to manage your brokerage account by talking to ChatGPT. The investing platform has integrated its Model Context Protocol (MCP) server with OpenAI’s chatbot, creating a direct pipeline between conversational AI and actual trade execution.
In English: you can now ask ChatGPT to analyze your portfolio, research stocks, and even place trades on Public, all through a chat interface. Every trade still requires your explicit confirmation before it goes through.
How the integration actually works
The connection runs on MCP, a framework OpenAI has been rolling out to let ChatGPT communicate with third-party services. To use it, Public users need to enable Developer Mode in ChatGPT and add the Public MCP connector. Once that’s set up, the AI can pull real-time data from your account and interact with it.
The integration supports trading across multiple asset classes: stocks, ETFs, options, bonds, and cryptocurrencies. Crypto services on the platform are facilitated through Zero Hash LLC.
