Progress Notifications Not Working in ChatGPT (MCP TS SDK 1.20.0)

Hey, this isn’t supported in ChatGPT right now. MCP Inspector may send a progressToken, but ChatGPT doesn’t currently expose/render MCP notifications/progress. On timeout: I don’t see a documented default timeout for ChatGPT’s web MCP client, so I wouldn’t build around a fixed number. For longer jobs, return quickly with a task/job ID and use polling instead.
