Working with UEASSET files in command line or UE4Editor headless mode?

Hi,
I am looking for resources or any information about working with UEASSET files without launching the editor or by launching the editor in a headless mode.

I am developing pipeline tools and asset tracking, and I need to query data or add custom metadata to UEASSETs on the fly. Cooking assets without opening the editor is also a goal.

As I understand it now, given that UE4 is opensourced, I should be able to wrap my own standalone cli to accomplish this, but I am curious if there either already exists such a capability in the editor binaries, or a tool for this purpose is out there in the wild.

Short of this, I would need to hook callbacks inside the editor while artists and devs are working to add this metadata, and query / add it when they use the UE4Editor source control integration we plan on using.

Looking forward to hearing about people’s experience and thoughts on this!

Did you ever get any information on this?
