fabric-permissions-api

by lucko

Permissions API gives other Fabric mods a shared way to run permission checks and read option values from a permission provider.

FabricServer-side onlyMIT LicenseOpen source1.17.1 – 26.3

What it does

Mods that need to ask whether a player may do something call the API instead of building their own permission system. Option metadata, such as a value attached to a permission, can be looked up through the same interface. Configuring permissions requires a separate permission manager mod that is compatible with this API.

Key features

  1. Permission checks

    Mods can run permission checks against whichever provider is installed, without knowing which one that is.

  2. Option lookups

    Option values attached to a permission can be read as metadata through the API.

  3. Developer documentation

    A USAGE.md file in the project explains how developers call the API.

Questions

Does a server need a permission manager as well?

Yes. This API only provides checks and lookups, so a compatible permission manager must be installed to set permissions.

What the author says

A simple permissions API for Fabric. It allows mods to easily run permission checks and lookup option (metadata) values against permission providers. If you want to configure permissions, you will also need to install a compatible permission manager mod.
