G1axNameHistory
by tech.anupam
G1axNameHistory adds in-chat commands that show a player's past usernames and UUID, for players who look up name changes on Fabric.
What it does
A player types a command in chat and the mod returns the name history and UUID of the named account. Lookups run as asynchronous requests with a one-hour local cache, so the game client keeps responding while results load. Clicking the UUID in chat copies it to the clipboard, and tab-completion suggests online players when typing a name.
The mod works on the client alone, so a player can use it on any server without installing anything there. It is released under the MIT License, and the source code, issue tracker and wiki are public. Files target 1.21 – 1.21.11 on Fabric, with 1.0.0 for 1.21.11 as the latest build, published on 2026-01-16.
Key features
Name history lookup
Typing a command in chat lists the past usernames attached to a Minecraft account.
UUID display
The account's UUID appears in chat alongside its name history.
Click to copy UUID
Clicking a UUID in chat places it on the clipboard without any extra step.
Tab-completion for online players
The command suggests names of players currently online as the player types.
Cached async requests
Results are cached locally for one hour, and requests run in the background so the client does not freeze.

Use cases
Tracking name changes
A player who knows an account under an older name can find its current and former names in chat.
Checking an account's UUID
Staff or players who need an account's UUID can copy it straight from the chat line.
Who it’s for: Players who look up other accounts' names and UUIDs, and server communities that check name changes. Because the environment is client-side only, each player who wants the commands installs the mod locally.
