An item becomes a tiny program. You assemble it by clicking - it stays editable forever.
When it runs - left-click, right-click, shoot, drop, move, equip, take damage and more.
What it does - pick from 200+ ready methods grouped by category. No syntax to remember.
Fill in the blanks - numbers, text, the player, or another method's result as a value.
Circles, filled discs, helixes, beams and coloured dust, anchored to any location and combined into spell effects. Fire them from any trigger and watch them play out in the world.
Define named stats like Strength, Vitality or True Defense and attach them to any item. Build full sets with bonuses, and talismans that apply their stats and abilities from anywhere in the inventory.
Pick from a growing library of ready methods grouped by category. Search, click, fill in the blanks. Each one shows its parameters and what it returns, so building an ability feels like building a sentence.
Store values on the item itself that travel with it. Show them in lore with {var_key} placeholders and redraw it live - perfect for upgrade levels, kill counters and charge meters that change as the item is used.
Left-click, right-click, shoot, drop, move, equip, take damage and 50+ server events. Each trigger hands your actions the variables it carries - the player, the item, the event - ready to use.
Set custom model data so items use your resource-pack models and textures while staying ordinary, stackable items. Morph an item's material on the fly so it can look like anything while it runs.
Run a local MCP server and hand one prompt to Claude, Cursor, Gemini or Codex. It reads every method, writes the item file and you can still open and edit every step in the GUI.
ItemsCore ships an open addon API. Drop in official addons to add reforges, equipment slots, skins and full wardrobes - all editable from the same menus.
No. Items are built in a visual in-game editor, and an AI can write them for you. The generated script is hidden - you never have to touch it.
Run the ItemsCore helper to set up a local MCP server. Any AI (Claude, Cursor, Gemini, Codex) connects to it, reads every method, and writes or edits item files for you. The full guide is in the docs.
Yes - that is the whole point. Importing an AI-written item rebuilds the same visual state the editor uses, so it opens and edits like an item you made by hand.
Minecraft 1.8 through 26.2. The correct version adapter is selected automatically at runtime.
Only that item is skipped - the rest of the plugin keeps working. /ic reload tells you exactly which item failed and why.
