NBT Autocomplete Mod FAQ
10 questions players actually ask, answered.
How do I get NBT autocomplete to show up while typing a command?
Start typing a command that accepts NBT, such as /summon, /give, or /data, and press Tab after the entity or item ID to trigger the suggestion list. Suggestions appear as you type inside the NBT braces, so keep the cursor within the { } block.
Why do I have to type the opening curly brace before suggestions appear?
The mod only activates inside an NBT compound, so it needs the opening { to know you are entering NBT data rather than a normal command argument. Type { first, then start typing a tag name and the matching suggestions will populate.
Does NBT Autocomplete work on a server or only in singleplayer?
It is a client-side mod, so it runs on your game and works in singleplayer and on any server you join. The server does not need the mod installed, and it will not change how commands are executed for other players.
Can I use NBT Autocomplete to summon a mob with custom tags like NoAI?
Yes, type /summon followed by the mob ID and an opening brace, then start typing the tag name and pick it from the list. The mod suggests the tag name so you can fill in the value yourself, such as setting NoAI to true.
How do I give myself an item with custom NBT data using the autocomplete?
Use /give with your name and the item ID, then open an NBT compound with { and let the mod suggest tags like display, Enchantments, or CustomModelData. Select the tag from the list and type its value to finish the command.
Can I edit an existing block entity's NBT with this mod's help?
Yes, target the block with /data get or /data merge and let the autocomplete suggest the NBT path as you type. The suggestions help you navigate nested tags so you can find the exact value you want to change.
Why are no suggestions showing up when I press Tab in a command?
Make sure you are inside an NBT compound with an open curly brace and that the command actually accepts NBT, since commands like /tp or /gamemode will not trigger it. If it still fails, check that the mod is enabled in your mod list and that no other command mod is overriding Tab completion.
Does NBT Autocomplete conflict with other command or autocomplete mods?
It can conflict with mods that also hook into command suggestions, since only one suggestion provider usually wins. If suggestions look wrong or missing, try disabling other command-completion mods one at a time to find the conflict.
Will this mod hurt my game's performance or FPS?
No, it only does work while you are typing a command and does not run anything during normal gameplay. The performance impact is negligible because it is not rendering or ticking anything in the world.
Does NBT Autocomplete show every NBT tag that exists, or only common ones?
It suggests tags based on the entity, item, or block you are targeting, so the list changes depending on context. Some obscure or modded tags may not appear, in which case you still need to type them manually.
