MCServer has the exact same axis system as Minecraft. I can't say which directions X and Z are, but the Y axis points upwards meaning 127 is the top block, and 0 is the bedrock at the bottom of the map.
If you're using OnBlockPlace or OnBlockDig for this, you always get the coordinates of the block you aimed at.
Use F3. Go to singleplayer and walk towards the sun. Z will increase. Go on MCServer walk towards the sun, Z will decrease. The Y axis is fine.
