Change ChatGPT App MCP Domain with new update
OpenAI Developer Community
May 9, 2026
Hey there,
I’d like to update the MCP server URL with a new update of my ChatGPT app, but the system does not allow me to do it.
Basically, I use a fly dot io domain, and now I have associated a custom domain and want to migrate to the new URL.
Anyone have some insight?
Thanks!
