Rechiseled x Open Parties and Claims
Java mod listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.
⬇ Download on Modrinth
A lightweight Fabric server-side addon that bridges Rechiseled and Open Parties and Claims (OPAC).

When a player hits blocks while holding a Chisel, an area of blocks is replaced with its variants. Open Parties and Claims does not recognize this interaction, meaning it can be exploited to grief other players' claims.
This mod ensures OPAC properly recognizes the interaction, blocking it if performed by anyone without the necessary claim permissions.
