I've nominated some Agents of SHIELD ships under MCU some days ago because I thought that was the way I had to, but looking at how messy the tag set looks now, and since you're asking for our input, I'd rather them moved under Agents of SHIELD, instead. I feel I agree with the guys above me, separating MCU into MCU Movies, Agents of SHIELD, Daredevil, Jessica Jones, and Agent Carter seems the best way to go.
