FabricServer-side onlyApache License 2.0Open source1.21.11

What it does

Open Parties and Claims, a server-side claim and party mod, has long commands. This mod adds aliases and simpler syntax on top of them, so a server operator or player types less to reach the same actions. The original commands keep working unchanged, so existing scripts and habits still apply. The mod runs on the server alone; players join without installing it. It requires Fabric API, Forge Config API Port and Open Parties and Claims, and is published for Fabric only, for 1.21.11, with 1.0.0 as the latest file. The source code is available under the Apache License 2.0, so the code is open source.

Key features

  1. Command aliases

    Shorter alias commands map onto the existing Open Parties and Claims commands.

  2. Simplified syntax

    Common claim and party actions take fewer arguments than their original forms.

  3. Original commands kept

    The standard Open Parties and Claims commands remain available alongside the new forms.
