Chunk Scanner
by uOrb
Chunk Scanner lets server admins locate item stacks inside saved container blocks without loading the chunks that hold them.
What it does
The mod searches the disk-based region files of a saved world for container inventories. It reads the .mca region files directly from the world folder, covering the overworld, the Nether and the End, and reports where a given item ID is stored. Item IDs such as minecraft:diamond or minecraft:dragon_egg can be searched, so admins can trace an item across the world without walking through each area.
Container block entities are detected and their stored inventories inspected. Chests, barrels, hoppers, droppers, dispensers and shulker boxes are covered. Large worlds are processed in batches, and scanning avoids live chunk loading to limit the effect on server performance. The use case is tracking down duped or misplaced items and stashes that players have hidden.
The mod is server-side only, so players join without installing it. It is published for Fabric alone, with a single build for 26.1.2, and the code is released under the MIT License but is not open source. Chunk Scanner is also the only build named for this version range on the Fabric loader in the catalog.
Key features
Region file scanning
Saved .mca region files are read from disk, so the scan does not depend on chunks being loaded.
Container inventory detection
Container block entities are found and their stored items are checked against the search target.
Item ID search
Searches accept namespaced item IDs, for example minecraft:diamond, and return where matching stacks are stored.
Batched processing
Large worlds are scanned in batches, which spreads the work over time instead of one long pass.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Finding duped items
Admins can search for an item that appears in unexpected amounts and locate the containers holding it.
Recovering misplaced stashes
A stash that a player has forgotten can be found by its item without manual searching of each base.
Who it’s for: Server administrators running Fabric servers who need to find items in stored containers across a saved world.
