Where can I find documentation for the Cuberite Tools?

IE MCADefrag, BlockZapper, etc. I have no idea what they do.

I'm sorry, but there isn't any good documentation for the tools really. I would try a search on the forum, and on GitHub in the issues section as that will hopefully give you some idea. Most of the tools are only really useful for development and debugging rather than being intended for end user use.

MCADefrag and BlockZapper could actually have some use for end-users, but they don't support the new 1.13 world format, and it's unlikely the support will be added.
