Description

Copy cuboid regions to files. Paste them back exactly where you mean to — anchored to your position.

Minecraft 26.1.2 Fabric Loader 0.19.2 Java 25 Version 2.1.0

Copy Paster is a Fabric client + server mod for survival and creative builders who want a fast, visual way to duplicate structures without leaving the game. Select a box in the world, name it in chat, then paste it later — position follows where you stand at copy time and paste time, so offsets stay intuitive.

  • Interactive /copy — click two corners; live wireframe preview while you aim
  • Paste ghost preview — cyan outline when blocks would be overwritten
  • Undo — /pasteundo restores the last paste (in-memory until restart)
  • Ukrainian (uk_ua) — full UI strings alongside English
  • Configurable highlights — config/copypaster.yml or optional Mod Menu + Cloth Config

Maintainer docs: CLAUDE.md · Release notes: CHANGELOG.md

Install

Where What
Dedicated server copy_paster-<version>.jar in mods/ + Fabric API
Each player Same JAR in client mods/ (required for /copy, previews, HUD)

Server-only mode: coordinate /copy x1 y1 z1 x2 y2 z2 and all /paste commands still work; bare /copy needs the client mod.

Optional: Mod Menu + Cloth Config for in-game highlight colour.

Quick start

1 · Save a region

  1. Stand at the anchor point you want for this copy.
  2. Run /copy.
  3. Attack corner 1, then corner 2 (blue wireframe follows your crosshair).
  4. Use (right-click) to cancel anytime.
  5. Type a structure name in chat (a–z, 0–9, _, -, max 64 chars). Type cancel to abort (60 s).

Legacy: /copy <x1> <y1> <z1> <x2> <y2> <z2> then name in chat — or bind [ / ] under Options → Controls → Miscellaneous (unbound by default).

2 · Paste it back

  1. Stand in the same relative spot you used when copying.
  2. /paste <name> — confirm with /paste <name> confirm if the ghost preview warns about overwrites.
  3. Save the undo ID from chat for /pasteundo <id>.
