OpenAI has introduced full Model Context Protocol (MCP) support in ChatGPT, allowing developers to use custom connectors for read and write actions within chats. This new feature, available in Developer Mode, enables integration with external systems and APIs, transforming ChatGPT into a programmable automation hub. Developers are advised to exercise caution due to the potential for prompt injection attacks and the risks associated with real write operations.

The open letter advocates for empowering developers to focus on building innovative technology while allowing automated systems to manage security concerns. It emphasizes the need for a balance between development and security to foster creativity and efficiency in the tech industry. The letter calls for a shift in perspective that trusts technology to handle security rather than stifling development through excessive regulations.
