ClientBlock

A Fabric Mod for blocking/filtering Minecraft clients (JUST SERVER SIDE!).

Configuration

The configuration file is created automatically inside your Fabric Mods configurations folder. The file is named clientblock.json which has this structure:

{
  // Json schema for having types in config
  "$schema": "https://raw.githubusercontent.com/arch-fan/ClientBlock/refs/heads/main/config.schema.json",
  "action": "block", // "block" or "allow" (block by default)
  "clients": [
    "fabric"
  ], // Array of clients to block or allow (based in action mode) (empty by default)
  "kickMessage": "Custom kick message", // The client is not allowed! ("The client is not allowed!" by default)
  "logger": false, // Where to log every single person client entering at the server (false by default)
  "whitelist": [
    "PlayerOne"
  ] // Array of players to bypass the client filter (empty by default)
}

Here you can copy the template without comments :)

{
  "$schema": "https://raw.githubusercontent.com/arch-fan/ClientBlock/refs/heads/main/config.schema.json",
  "action": "block",
  "clients": [
    "fabric"
  ],
  "kickMessage": "Custom kick message",
  "logger": false,
  "whitelist": [
    "PlayerOne"
  ]
}
