  "textContent": "Welcome to the dev Community, @Tade95!\n\nThanks for sharing the detailed breakdown.\n\nBased on what you described, the connection and read tool discovery appear to be working, but the write tool calls are being blocked before they reach your MCP server.\n\nAccording to the Help Center, full MCP support, including write/modify actions, is currently rolling out in beta for ChatGPT Business, Enterprise, and Edu.\n\nFor write/modify actions, ChatGPT may ask for confirmation depending on the app permissions, the action context, and the potential impact of the action. In some cases, especially risky actions may be blocked instead of being presented for approval, which could explain why the request is not reaching your server.\n\nOne clarification: OpenAI-built apps are currently search-only and do not support write actions, so behavior with apps like Google Drive may not be directly comparable to a custom MCP app.\n\nIf you’ve already opened a Support ticket, could you please share the ticket number here? That will help us investigate this further with the relevant context. If not, please open one and include the workspace ID, app name, exact error text, timestamps, affected write tool details, and any relevant MCP server/tool metadata.\n\nThanks again for flagging this.\n\n~ Smith",
