Minecraft Region Fixer

The Minecraft Region Fixer is a tool (Python script) used to fix a broken world (which is not always possible). It doesn’t have to be just a corrupted world, but for example a world where there are an extreme amount of entities, causing the server to automatically crash on startup.

MCASelector

MCASelector is “a tool for selecting parts of Minecraft worlds for removal or export”.

A specific example of use might be deleting generated “empty chunks” (chunks with no activity in them) to free up disk space.

This tool is written in Java and provides a CLI (can be run with a command), so if you can edit the start command (or its flags), it can be run on shared hosting.

NBTExplorer

The NBTExplorer is a tool that allows you to edit NBT files.
