This mod blocks the default commands that non-OP players can use when running a Minecraft server.

By default, it blocks these commands:

/help
/list
/me
/msg
/random
/teammsg
/tell
/tm
/trigger
/w

Operators can manage the block list in-game with these commands:

`/cblock block`
`/cblock allow`

Ex). /cblock worldedit allow Ex). /cblock spark allow Ex). /cblock vanish allow

Blocked commands are saved to a config file, so your settings stay after server restarts.

This mod is designed for server owners who want tighter control over which commands regular players can use, while still allowing operators full access.
