Minecraft like A* pathfinding that auto jump over 1 block?

I’m trying to create an AI unit that move with pathfinding. The pathfinding is fine, the obstacle avoidance is fine. Then I set the height to test the pathfinding. It’s fine when I give a 60 degree slope 60 when moving using character controller. But in minecraft, the mobs tend to jump whenever they meet a 1 block height in front of it. The pathfinding works fine because I see the green arrow pointing on the right spot on high ground. But my units doesnt jump.

Is there any suggestion to make them jump when a 1 block height blocking them?
