Auto Builder Bot Request

Would it be possible for someone to create or link me to a minecraft Auto Builder? Although, the type i am looking for is one that will use items from your inventory (like rightclicking with a stack of dirt will create a dirt hut/wall/floor/pole/structure). What i am not looking for is a Mod that will add a new item to the game. I want to be able to use this in multiplayer to create a quick structure.

My Main point is, can anyone make/link me to a mod that creates a structure when you place a block (like Epsilon Client's place hack) that is possible to use in multiplayer without the server needing a plugin for it!

will u pay for this?
