These commands can also be called “server commands” but effect who can play, and the experience they have. The server must be running for these commands to be used.
<server> whitelist|wl on|off
A whitelist is a set of names defining who is allowed onto a server. If a player attempts to logon to a server with a whitelist enabled, and their name is not on that whitelist, they cannot join and are told why. This command turns a whitelist on or off.
Note the use of the | character means “or”, for example msm creativeserver whitelist on is acceptable or msm creativeserver wl off, but not msm creativeserver wl on off or msm creativeserver whitelist wl on or msm creativeserver whitelist on|off.
<server> whitelist|wl list
Lists the players who are on the whitelist.
<server> whitelist|wl add|remove <player>
Adds a player to, or removes them from the whitelist.
<server> blacklist|bl list
Lists the players who are blacklisted. A blacklisted player cannot join a server, even if that person is also whitelisted. A difference from whitelisting is that in addition to players, an IP can be blacklisted. This command outputs both blacklisted players and IP address.
<server> blacklist|bl player add|remove <player>
Adds or removes a player from the blacklist.
<server> blacklist|bl ip add|remove <ip-address>
Adds or removes an IP address from the blacklist.
<server> operator|op add|remove <player>
Adds or removes operator status for a player. Operators are also considered whitelisted.
<server> operator|op list
Lists the players who are operators.
<server> gamemode|gm survival|creative <player>
Sets a player’s game mode to either survival or creative.
<server> kick <player>
Forcibly disconnects a player.
<server> say <message>
Broadcast a message to all players which appears in bright pink, the invocation msm creativeserver say Hello all would produce: [SERVER]: Hello all.
<server> time set|add <number>
Set or increment the in-game time of day. The number must be between 0 and 24000.
<server> toggledownfall
Toggles any rain or snow downfall.
<server> give <player> <item> [amount] [data]
Gives an item to a player who is online right now. See this wiki page for an exhaustive list of item codes. The amount argument defaults to 1 if omitted, and the data argument is (as far as is known) used for applying damage to items which degrade with use. This damage value equates to the number of “uses” a tool has undergone. Remember a diamond pickaxe can take more damage than a stone pickaxe.
<server> xp <player> <amount>
Gives experience to a player who is online right now. The amount can be a positive or negative integer. Negative integers detract from the amount of experience a player has.
<server> save on|off
Enables or disables “saving” of world changes to file. In-game players can still make changes to the world whilst saving is off, but rebooting the server would mean loosing those changes. Any changes made whilst saving is off are queued, meaning they are saved to file when saving is enabled again.
<server> save all
Forces the writing of all pending unsaved changes to file.
<server> cmd <command>
Sends a command to the server, for example: msm creativeserver cmd tp craftysaurus MrWizardBeef.
<server> cmdlog <command>
Like the previous command, sends a string to the server to execute, but in addition outputs the server log to the screen afterwards. You can stop watching the log output by pressing Ctrl+C.
