You have two options: * Use it as a "source": chatgpt -> settings -> apps & connectors -> add it as your connector. This supports only 2 functions: search, and fetch; details: https://help.openai.com/en/articles/11487775-connectors-in-chatgpt https://help.openai.com/en/articles/11487775-connectors-in-c... ; in business / edu version there is support for "full MCP mode": https://help.openai.com/en/articles/12584461-developer-mode-and-full-mcp-connectors-in-chatgpt-beta https://help.openai.com/en/articles/12584461-developer-mode-... * Enable "developer mode" chatgpt -> settings -> apps & connectors -> advanced settings -> developer mode. Available on paid&pro levels only. This can do full MCP access, but can't (currently) use your memory settings. The option that works under all conditions is to use the API, and add it as a function directly (no MCP) -this works regardless what plan you have on openai.
