Live Whitelist
by cyber98
Live Whitelist lets a Forge server check each joining player's UUID against an external API, so an outside service such as a Discord bot can allow or refuse connections.
What it does
The server sends each connection request to the base URL set in config.json. The reply decides whether the player may join. A false answer blocks the connection and shows the message string set in the config. The API must answer within about 2 seconds, or the player is kicked before the check finishes. The site must accept plain HTTP connections from the server, and the API needs at least one endpoint that verifies a UUID.
Setup follows the included JSON guide for the response format. Running the bundled script requires script execution to be enabled in Windows, and the script installs its required packages after a short wait. The script then writes config.json, where the API URL and the access token are filled in. After that the server is ready to use. Live Whitelist runs on the server only, so players join without installing anything. It is published for Forge only, for game versions 1.20.1 – 1.20.6, and is open source under the Apache License 2.0.
Key features
UUID-based access check
Each player's UUID is sent to an external endpoint, which answers whether that account may connect.
Configurable API endpoint
The base URL, access token and rejection message are set in config.json, so the check can point at any compatible service.
Discord bot integration
A Discord bot can hold the allow and disallow list, and the server asks it about each connection.
Timeout-sensitive checks
The server waits about 2 seconds for the reply, so the API needs to respond quickly.
Guided setup script
A bundled script installs the required packages and creates the config file from the values entered.
