CraftBlocker

A lightweight Paper plugin that lets you control exactly which items your players are allowed to craft — fully configurable, no restart required.

Features

• Config-driven crafting control — decide what's blocked entirely through config.yml, no code changes needed.
• Two modes:
  • block-selected — only the items listed in your config are blocked from crafting.
  • block-all-without-selected — everything is blocked except the items listed in your config.
• In-game management via the /craftblocker command — no need to touch files or restart the server.
• Smart tab completion — typing /craftblocker add ob instantly suggests matching blocks like obsidian.
• Instant reload — apply config changes on the fly with /craftblocker reload.
• Minimal footprint — no external dependencies, built directly against the Paper API.
