A server-side command logging mod.
About this Mod
Feeling like you need to have control over what commands players are using on your server? Need to destroy that nasty repeating command block sending /kill @e?
Command Spy
A mod that logs commands, executed by players, command blocks and signs to console / players. Additionally, position of executor block and player uuid is appended as well.
Features
Supports blacklisting commands.
Messages can be customised / disabled via generated config.
Permissions
CommandSpy supports LuckPerms.
If the mod is loaded, logToOps will be redundant - instead, mod will check if players
have the permission to receive info about commands being executed.
commandspy.log.command_blocks-> this player will receive info of command blocks executing the commandcommandspy.log.signs-> this player will receive info of signs executing the commandcommandspy.log.players-> this player will receive info of players executing the command
Oh, this icon ... Terrible!
Current icon is more of a placeholder and I'd love to change it for something nicer! DM me if you have one!
