Dynamically Whitelist

Dynamically Whitelist is a mod that replaces the standard Minecraft JSON whitelist with an automated system.

When a player joins, the mod sends a POST request to an API connected to your database. The API verifies the player and returns:

200 — the player is allowed to join

403 — the player is denied, and the mod disconnects them

POST request format:

{
  "uuid": "<UUID of the joining player>"
}

This allows the server to manage whitelist entries dynamically without manually editing the JSON file. In the future, direct database integration may also be added.
