Tophat
by JustJabka
Tophat is a Fabric library that exposes server-side utilities through datapacks, covering GUI menus, player data access and related helpers.
What it does
Tophat adds a set of utilities that datapacks can call. Its main area is player data access: the vanilla data command can read and modify a player's stored data, so pack authors do not need custom Java code for that. Menu handling is covered as well, with commands that open a menu for a player and close the one they have open.
Closing a menu can be limited to a specified menu type, and opening a menu can name a container and choose whether it opens on top of other menus, with that option off by default. The mod is server-side only, so players join without installing it, and it requires Fabric API. Files are published for Fabric alone, for the 26.2 game version, with 1.0.0 as the latest file from 2026-07-05. The full set of functions is described on the project wiki, and the source code is released under the MIT License, which makes the mod open source.

Use cases
Datapack interfaces
Pack authors can open custom menus for players from a function, then close them when the interaction ends.
Player data edits on a server
Server owners running command-driven content can read or change player data with the vanilla data command.
Who it’s for: Datapack authors and server owners who want menu and player data helpers without writing a Java mod of their own. Players need nothing installed, since the mod runs only on the server.
