Mousie Builder Toolkit is a Fabric mod designed for builders who enjoy precise, flexible, and slightly impossible construction.
Hold Left Alt (default keybind: Open Toolkit) to open Mousie's menu, then hover over each button for a short description. The mod introduces tools that extend vanilla Minecraft building rules, allowing block placement and editing beyond normal limitations.
The mod works in both single-player and multiplayer. On servers, it must be installed on both client and server, and players require operator permissions to access the full toolkit. Without OP, the menu can still be opened, but tools remain locked.
Current Tools 
- Still Paws – Prevents block updates, physics, fluid ticks, growth ticks, and scheduled block reactions.
- Cheese Logic – Allows block placement without normal support or placement restrictions.
- Extend Tail – Extends block interaction range with selectable distances.
- Ruffled Fur – Adjusts flight speed in Creative and Spectator modes.
- Moon Sight – Toggles Night Vision and detects existing effects from potions or commands.
- Gamemode Buttons – Quickly switch between Survival, Creative, Spectator, and Adventure.
- Cheese Guard, Glowbug & Tweak Stick – Instantly equips or selects Barrier, Light, and Debug Stick items.
Spoiler
More tools and buttons will be added in future updates. Mousie is still conducting experiments that may or may not be safe for block physics.
⚙ Controls: The menu key can be changed in Minecraft controls: Options → Controls → Key Binds → Mousie Builder Toolkit → Open Toolkit. If Mod Menu is installed, keybinds can also be configured through the mod's settings screen.
