Auto Swap

Client-side mod that automates inventory management and equipment swapping during gameplay. Detects durability loss, empty item stacks, and block-breaking actions to equip the correct items from your inventory automatically.

Client-side only (no server installation required). Fully compatible with singleplayer.

Free to use in any modpack — public or private, no permission needed.

What it does

• Smart Tool Selection — switches to the most efficient tool the moment you start mining, and won't replace a tool that's already the right type.
• Auto Weapon on Attack — optionally draws your best sword the instant you start hitting a mob. Disable it and AutoSwap will never swap off your weapon while a mob is in your crosshair.
• Gear Replacement — automatically equips a matching tool, weapon, or armor piece when the currently equipped one breaks.
• Offhand Replenishment — refills your off-hand when the held item runs out. Add a Totem of Undying, shield, or any item via the built-in item picker or by item ID.
• Stack Refills — refills the active hotbar slot with identical blocks or torches when the current stack is depleted.
• Double-Jump Elytra — equips an elytra from your inventory on double jump, and swaps your chestplate back on landing.
• Restore After Auto-Tool — puts the item you were holding back in your hand once you stop mining.

Configuration

All features are fully modular and can be toggled individually through the in-game settings screen, the config file, or via keybinds under Controls → AutoSwap.

Details

• Client-side only.
