ChatGPT Apps triggers Auth flow when MCP transport is stateless
OpenAI Developer Community
March 20, 2026
Hello,
It seems that when changing the MCP transport to the stateless version, ChatGPT apps stop working. Is this expected?
I can successfully add a Dev connector, but when starting to use it, inside the ChatGPT costumer chat, it triggers the “Auth” dialog, accepting, results in a loop, and reject it, in a failure.
The MCP does not have any authentication and I already validated that the tool can be called in the Chat development platform.
Thank you.
