RunPlayer
Java mod listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.
A plugin that runs as a different player, but without requiring any permissions or op. Made for server admins.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
RunPlayer
A powerful administrative tool for Minecraft 1.21 servers that allows Operators to force players to execute commands without granting them actual permissions or OP status.
Features
- Ghost Execution: Commands are run via a temporary wrapper. The player never actually receives the permission node or OP status.
- Security Blacklist: Prevent the command from being used to run sensitive commands (like
/opor/stop). - Identity Retention: Plugins that target the "executor" will still target the player, not the admin who ran the command.
Commands
/runfor <player> <command>: Executes a command as the specified player. (Requires OP)
Configuration
You can block specific commands in the config.yml:
blacklisted-commands:
- "op"
- "deop"
- "stop"
- "luckperms"
