Server Eye
by Alexkist
Server Eye lets server owners block specific mods from being joined by players, with commands to view and reload its settings.
What it does
Server Eye stops players from joining a server when they run mods the owner has listed as blocked. The blocklist is set in the server configuration, and each entry is matched by the mod's ID, which is always lowercase and is shown under the mod's version in the mod list. A timeout setting controls how long the check waits, and setting it to 0 disables the feature.
The mod is published for Forge and NeoForge, with files for 1.20.1 and 1.21.1, and it runs on client and server, so both the server and every player need it. Its commands use permission nodes that begin with the mod ID, and they can be granted through LuckPerms, which is an optional dependency. The code is open source under the GNU Affero General Public License v3.0 only.
Key features
Blocked mod list
The server configuration lists the mod IDs that players may not join with, and any player running a listed mod is refused.
View mods command
A command lists the mods the server sees on the joining player's side, which helps with building the blocklist.
Reload command
A reload command re-reads the Server Eye configuration without restarting the server.
Permission nodes
Each command has a permission node starting with the mod ID, so access can be given to specific staff members.

How it compares
CustomPerm is a NeoForge-only permission mod with a custom license, server-side only and not open source, for 1.21.1 – 1.21.11. In-Game NBTEdit Reborn runs on Fabric, Forge and NeoForge across 1.16.5 – 1.21.11, and it is open source under the GNU General Public License v3.0 only. Both differ from Server Eye in what they do: they manage permissions or edit data instead of blocking joins.
