Client Data Command
by NoEul
Client Data Command adds a client-sided /data command that lets a player read and edit NBT on the client side without holding a permission level.
What it does
The mod registers a client-sided data command. Because it runs on the player's own client, the command reads block entity and storage NBT that the client can access, and a player can view that data without operator permission on the server. Editing follows the familiar /data pattern, with append, insert, merge, prepend and set modes for changing the stored values.
Client Data Command is a client-only utility. Only the client needs it, and servers run without it. The fabric loader is required, as is Fabric API. Mod Menu is optional and only adds a configuration entry point. The mod is published for Fabric alone, across six game versions 1.21 – 1.21.5, and it is released under the MIT License as open source. Snapshot builds are also published.
Key features
Client-sided data command
A /data command that runs on the client, so the player inspects NBT without a server-side permission.
Block entity access
The command reads the NBT of block entities the player is looking at, for quicker inspection than a wiki lookup.
Merge and set modes
Stored values can be changed with append, insert, merge, prepend or set, matching the vanilla data command syntax.
Shorthand command name
A shorter Client-Data form of the command is registered alongside the main one for faster typing.

Use cases
Inspecting NBT without operator rights
A player on a server without operator rights can still view block entity data through the client command.
Checking storage data
The command also covers storage data, so a player can look at values held in command storage on the client.
Who it’s for: Players who want to inspect NBT on a server where they hold no operator permission, and players who work with data packs and command storage in single-player.
