MagicalChalk is a Minecraft mod for creating, importing, exporting and placing structures in Minecraft Java Edition 1.21.1 with NeoForge 21.1.x. It supports single-player, LAN and server play, including dedicated servers. Structure Chalk lets players mark an area by clicking two corners and save it to the server’s world storage. A selected blueprint can then be placed in-game with Magical Chalk, replacing obstacles. The mod works with .chalk, .json and .nbt files and converts .litematic, .schem and vanilla structure .nbt files. Its import manager can search files and show metadata such as dimensions, volume, block count and file size. Magic Chalk Studio provides placement, brush, line, shape, selection, paste and erase tools, with undo and redo shortcuts. A public API lets other mods register structures and associate them with biomes using JSON or Java. LuckPerms is optional; without it, most admin actions require OP level 2 by default. The interface is translated into English and French. MagicalChalk is free and MIT licensed.
