I have a mod in plater link to ex method dungeon tool, part of the code points directly to MDT addon:

    if MethodDungeonTools ~= nil and MethodDungeonTools.GetEnemyForces ~= nil then
        local mobPercentageString = ""
        local weight = nil;
        local isTeeming = envTable.isTeeming()
        local npcId = unitFrame.namePlateNpcId
        local count, max, maxTeeming, teemingCount = MethodDungeonTools:GetEnemyForces(npcId)

Mob percetange in keys is still working but i will like to ask if this is going to change to MythicDungeonTool so i may have to change this part of the code in plater mod.
Linto the mod: https://wago.io/M8ejNxoo_

TY

MethodDungeonTools:GetEnemyForces(npcId)
will work until 9.0
The new way to call this function now is:
MDT:GetEnemyForces(npcId)
