Works fine for me.

taylor@falcon:~/$ docker pull ghcr.io/open-webui/mcpo

Using default tag: latest

Check if you're signed into a docker org that restricts things, otherwise I'd guess network issue.

Hi @taylorwilsdon, I’d like to investigate and work on this issue.

Since the image can be pulled successfully in other environments, I’ll look into whether this is related to GHCR authentication, Docker organization restrictions, or a network/configuration issue on macOS.

I can also try to reproduce the issue with a clean Docker setup and document the findings/workaround.

Could you assign this issue to me?
