Wrench Finder
Java mod listed for Minecraft 1.20–1.21. Downloads from the MC Java Mods app on Android.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Wrench Finder
Wrench Finder lets you aim at a block and press a key (Default Z) to pull a matching item into your main hand from everywhere.
Storage
- Supports using items from the Inventory, the armor slots and Curios accessory slots.
- Supports using items from L2 Backpacks(1.21.1).

Block-Item
Wrench Finder uses an ordered Block-Item mapping table on the client side. It has a default rule that coves almost all tech mod.
- Each rule contains one
blockPatternand one ordereditemPatternslist. - When you press the key while aiming at a block, the mod compares the block id against
lookupRulesfrom top to bottom. - The first matching rule wins.
- Inside that rule,
itemPatternsare also checked from top to bottom. - The first item pattern that can be found in your inventory or supported remote storage is moved into the main hand.
The config data shape is effectively:
[
{
"blockPattern": "minecraft:bedrock",
"itemPatterns": [
{
"value": "create:wrench"
},
{
"value": "minecraft:barrier"
}
]
},
{
"blockPattern": "*create*:*",
"itemPatterns": [
{
"value": "create:wrench"
}
]
}
]
Pattern matching uses simple glob syntax:
*matches any number of characters.- Matching is done against the full registry id, such as
create:shaftorminecraft:crafting_table. create:*matches every id whose namespace is exactlycreate.*create*:*matches every id whose namespace containscreate, such ascreate:shaftandcreatedeco:andesite_sheet.minecraft:*_planksmatches item or block ids likeminecraft:oak_planks.
Examples:
minecraft:bedrock -> [create:wrench, minecraft:barrier]Trying bedrock will first search forcreate:wrench; if not found, it will tryminecraft:barrier.botania:* -> [botania:dreamwood_wand, botania:twigwand]Any Botania block can map to either wand, in priority order.*ae*:* -> [ae2:network_tool, ae2:certus_quartz_wrench, ae2:nether_quartz_wrench]Any block whose namespace containsaewill try these three AE2 tools in order.
If no explicit rule matches and fallbackToBlockItem is enabled, Wrench Finder will try the block's own item form.
