Access to the Oasis commands are controlled through a number of means. Of course, the master command list (in interpreter.c) specifies the minimum level for a player to call the command. This is typically set to either LVL_BUILDER, or LVL_GOD. A few commands are restricted to the implementor. A player can always edit a zone and its contents if their name is in the zone builders list (see ZEDIT for more information). Finally, a player may be granted OLC rights to a specific zone by means of the "set" command, using "set <player> olc <zone>". The implementor has unfettered access to all Oasis commands.
