Dynamically Whitelist

by DaimonCity

Dynamically Whitelist lets a Fabric server decide player access by asking an external API whenever someone joins.

FabricServer-side onlyMIT LicenseOpen source1.21 – 1.21.1

What it does

When a player connects, the server sends a POST request to a configured API, which checks the player against a connected database keyed by UUID. A 200 response lets the player in, while a 403 response denies access and disconnects them. Server owners can then manage whitelist entries without editing the JSON whitelist file by hand. Direct database integration is noted as planned for later.

Installation needs Fabric API, and the mod is server-side only, so players join without installing anything. Its latest file is 0.1.0 for 1.21.1, published 2026-02-06 on the beta channel, and the release builds cover 1.21 and 1.21.1 under the MIT License.

Key features

  1. Remote access check

    Each join triggers a POST request to the configured API, which returns the decision for that player.

  2. UUID-based lookup

    The API checks players against a database that stores their UUIDs, so entries are tied to accounts.

  3. Dynamic whitelist entries

    Server managers update access through the database and API instead of editing the whitelist JSON file.
