Essential Permissions Mod (1.21.8, 1.20.1) – Fine-Grained Command Permissions for Vanilla Minecraft

Essential Permissions Mod (1.21.8, 1.20.1) introduces a node-based permission system into vanilla Minecraft, allowing precise control over command access without relying on traditional OP levels. Ideal for server owners, map makers, or technical players, this mod is fully compatible with the Brigadier command framework and works seamlessly on both Fabric and modded servers.

OP Simulation for Clients
Clients with proper permissions can interact with operator-only features like gamemode switcher or structure blocks, even without full OP status.
Advanced /execute Modifiers
Includes custom modifiers for feedback and context-based permission checks.
Client and Server-Side Compatibility

execute if permission @s group.admin run say I am an admin
→ Allows datapacks or command blocks to check for custom permission groups
execute feedback silent run say hello
→ Silences feedback from commands
execute feedback console run command
→ Sends feedback to console only

✅ OP Level Simulation:

execute oplevel entity @s run teleport ~ ~10 ~
