OpenAI has introduced a game-changing feature: ChatGPT Developer Mode, powered by GPT-4o. Available to Plus and Pro subscribers, this beta mode provides full access to the Model Context Protocol (MCP) client. With it, developers can directly manage tools, enhancing both efficiency and customization. So, read ahead to know what this mode brings for the users!
What Is ChatGPT Developer Mode?

ChatGPT Developer Mode allows developers to control tools via connectors with read and write capabilities. OpenAI warns it’s powerful but risky, designed for developers who know how to configure and test connectors safely. Here’s what you need to know:
- Access: Available for Plus and Pro subscribers on the web.
- Activation: Enable via Settings → Connectors → Advanced → Developer Mode.
- MCP Import: Add a remote MCP server in the Connectors tab using SSE or streaming HTTP protocols, with OAuth or no authentication.
- Tool Management: Toggle tools on/off, refresh connector data, and use custom prompts to call specific tools.

- Safety Measures: Write actions need user confirmation. OpenAI advises inspecting JSON payloads to avoid data errors or misuse.
- Tool Clarity: Specify tools clearly, e.g., “Use Acme CRM’s update_record tool,” to prevent ambiguity.
- Data Visibility: View tool input/output for debugging and verification.
- Approval Options: Choose to remember tool approval/denial within a conversation, but trust only reliable apps.
OpenAI stresses careful tool selection to avoid overlaps and ensure smooth operation. The readOnlyHint annotation flags tools as read-only; others are treated as write actions, requiring extra caution.
This feature could redefine how developers interact with ChatGPT, streamlining workflows and replacing complex tasks traditionally handled by senior employees. However, OpenAI emphasizes responsible use to prevent data mishaps.
Developers can now debug, verify, and customize tools with unprecedented control. As ChatGPT Developer Mode rolls out, it promises to enhance productivity while demanding careful handling. Stay updated as OpenAI refines this powerful tool for the future.
