PEx and a simple mcMMO command

I am trying to setup a simple permission for mcMMO that will be a one time use and then I am just going to be getting rid of it as I wont need it any longer.

What I am trying to do is set it up so I can import mods into mcMMO's mod file so I can use those mods with mcMMO.

so far I have tried this and using the command /mcimport in game and it still does not work.

groups:
default:
default: true
prefix: '&e'
permissions:
- mcmmo.commands.mcimport

What am I missing? These permissions just are not making any sense to me.

Thanks for any help anyone has to offer!

 

Yes client side mods, like underground biomes, biomes o plenty, simple ores, moar ores. So that I can use the mcMMO skills on those blocks/trees.

 

Moved to alternatives since this will require Cauldron/MCPC+
