How to use the dedicated server


This is an early release (alpha) which we don't fully support yet. It might contain severe issues and we could stop supporting it at any time.

Recommended Hardware

We recommend running the Bedrock Minecraft Server on 64-bit Intel or AMD processor machines with at least 2 cores and 1 Gb RAM.



The Linux version of the Bedrock Server requires Ubuntu 18 or later. Other distributions are not supported. Unzip the container file into an empty folder. Start the server with the following command:

LD_LIBRARY_PATH=. ./bedrock_server


The Windows version of the Bedrock Server requires either:

Unzip the container file into an empty folder. Start the server by executing the bedrock_server.exe file.

On some systems, when you wish to connect to the server using a client running on the same machine as the server is running on, you will need to exempt the Minecraft client from UWP loopback restrictions:

CheckNetIsolation.exe LoopbackExempt –a –p=S-1-15-2-1958404141-86561845-1752920682-3514627264-368642714-62675701-733520436


The server will try to read a file named Some of these options are only read when a new world is created, while some others are read every startup. The file should contain a list with keys and values separated with an equal sign, one per line.

The following options are available. If a value as a number in parenthesis, that number can be used instead of the text value.

Option name Possible values Default value When is it used Notes
gamemode survival (0), creative (1), adventure (2) survival Always or only for new players
force-gamemode true, false false Always force-gamemode=false(or force-gamemode is not defined in the file) prevents the server for sending to the client gamemode values other than the gamemode value saved by the server during world creation even if those values are set in file after world creation.
force-gamemode=true forces the server to send to the client gamemode values other than the gamemode value saved by the server during world creation if those values are set in file after world creation.
difficulty peaceful (0), easy (1), normal (2), hard (3) easy Always
level-type FLAT, LEGACY, DEFAULT DEFAULT World creation
server-name Any string Dedicated Server Always This is the server name shown in the in-game server list.
max-players Any integer 10 Always The maximum numbers of players that should be able to play on the server. Higher values have performance impact.
server-port Any integer 19132 Always
server-portv6 Any integer 19133 Always
level-name Any string level Always The name of level to be used/generated. Each level has its own folder in /worlds.
level-seed Any string World creation The seed to be used for randomizing the world. If left empty a seed will be chosen at random.
online-mode true, false true Always If true then all connected players must be authenticated to Xbox Live. Clients connecting to remote (non-LAN) servers will always require Xbox Live authentication regardless of this setting. If the server accepts connections from the Internet, then it's highly recommended to enable online-mode.
white-list true, false false Always If true then all connected players must be listed in the separate whitelist.json file. See the Whitelist section.
allow-cheats true, false false Always
view-distance Any integer 10 Always The maximum allowed view distance. Higher values have performance impact.
player-idle-timeout Any integer 30 Always After a player has idled for this many minutes they will be kicked. If set to 0 then players can idle indefinitely.
max-threads Any integer 8 Always Maximum number of threads the server will try to use.
tick-distance An integer in the range [4, 12] 4 Always The world will be ticked this many chunks away from any player. Higher values have performance impact.
default-player-permission-level visitor, member, operator member Always Which permission level new players will have when they join for the first time.
texturepack-required true, false false Always If the world uses any specific texture packs then this setting will force the client to use it.
content-log-file-enabled true, false false Always Enables logging content errors to a file.
compression-threshold An integer in the range [0-65535] 1 Always Determines the smallest size of raw network payload to compress. Can be used to experiment with CPU-bandwidth tradeoffs.
server-authoritative-movement true, false true Always Enables server authoritative movement. If true, the server will replay local user input on the server and send down corrections when the client's position doesn't match the server's. Corrections will only happen if correct-player-movement is set to true.
player-movement-score-threshold Any positive integer 20 Always The number of incongruent time intervals needed before abnormal behavior is reported. In other words, how many times a player does something suspicious before we take action. Only relevant for server-authoritative-movement.
player-movement-distance-threshold Any positive float 0.3 Always The difference between server and client positions that needs to be exceeded before abnormal behavior is registered. Only relevant for server-authoritative-movement.
player-movement-duration-threshold-in-ms Any positive integer 500 Always The duration of time the server and client positions can be out of sync (as defined by player-movement-distance-threshold) before the abnormal movement score is incremented. This value is defined in milliseconds. Only relevant for server-authoritative-movement.
correct-player-movement true, false false Always If true, the client position will get corrected to the server position if the movement score exceeds the threshold. Only relevant for server-authoritative-movement. We don't recommend enabling this as of yet; work is still in progress.


When unpacking you will see a few folders and the binary executable. When starting the server for the first time a bunch of new (empty) folders will be created. The folders you should care about are the following:

Folder name Purpose
behavior_packs This is where new behavior packs can be installed. At the moment there's no way of activating them in a level.
resource_packs This is where new resource packs can be installed. At the moment there's no way of activating them in a level.
worlds This folder will be created at startup if it doesn't already exist. Every world created will have a folder named according to their level-name inside the file.


If the white-list property is enabled in then the server will only allow selected users to connect. To allow a user to connect you need to know their Xbox Live Gamertag. The easiest way to add a user to the whitelist is to use the command whitelist add <Gamertag> (eg: whitelist add ExampleName). Note: If there is a white-space in the Gamertag you need to enclose it with double quotes: whitelist add "Example Name"

If you later want to remove someone from the list you can use the command whitelist remove <Gamertag>.

The whitelist will be saved in a file called whitelist.json. If you want to automate the process of adding or removing players from it you can do so. After you've modified the file you need to run the command whitelist reload to make sure that the server knows about your new change.

The file contains a JSON array with objects that contains the following key/values.

Key Type Value
name String The gamertag of the user.
xuid String Optional. The XUID of the user. If it's not set then it will be populated when someone with a matching name connects.
ignoresPlayerLimit Boolean True if this user should not count towards the maximum player limit. Currently there's another soft limit of 30 (or 1 higher than the specified number of max players) connected players, even if players use this option. The intention for this is to have some players be able to join even if the server is full.

Example whitelist.json file:

        "ignoresPlayerLimit": false,
        "name": "MyPlayer"
        "ignoresPlayerLimit": false,
        "name": "AnotherPlayer",
        "xuid": "274817248"


You can adjust player specific permissions by assigning them roles in the permissions.json that is placed in the same directory as the server executable. The file contains a simple JSON object with XUIDs and permissions. Valid permissions are: operator, member, visitor. Every player that connects with these accounts will be treated according to the set premission. If you change this file while the server is running, then run the command permission reload to make sure that the server knows about your new change. You could also list the current permissions with permission list. Note that online-mode needs to be enabled for this feature to work since xuid requires online verification of the user account. If a new player that is not in this list connects, the default-player-permission-level option will apply.

Example permissions.json file:

        "permission": "operator",
        "xuid": "451298348"
        "permission": "member",
        "xuid": "52819329"
        "permission": "visitor",
        "xuid": "234114123"

Crash reporting

If the server crashes it will automatically send us various information that helps us solve it for the future.


You can issue commands to the server by typing in the console. The following commands are available. < > means a parameter is required, [ ] means it's optional and | denotes different allowed values. Strings can be enclosed in double quotes, ", if they contain spaces.

Command syntax Description
kick <player name or xuid> <reason> Immediately kicks a player. The reason will be shown on the kicked players screen.
stop Shuts down the server gracefully.
save <hold | resume | query> Used to make atomic backups while the server is running. See the backup section for more information.
whitelist <on | off | list | reload>

on and off turns the whitelist on and off. Note that this does not change the value in the file!

list prints the current whitelist used by the server

reload makes the server reload the whitelist from the file.

See the Whitelist section for more information.

whitelist <add | remove> <name> Adds or removes a player from the whitelist file. The name parameter should be the Xbox Gamertag of the player you want to add or remove. You don't need to specify a XUID here, it will be resolved the first time the player connects.

See the Whitelist section for more information.
permission <list | reload>

list prints the current used operator list.

reload makes the server reload the operator list from the ops file.

See the Permissions section for more information.

op <player>

Promote a player to operator. This will also persist in permissions.json if the player is authenticated to XBL. If permissions.json is missing it will be created. If the player is not connected to XBL, the player is promoted for the current server session and it will not be persisted on disk. Defualt server permission level will be assigned to the player after a server restart.

deop <player>

Demote a player to member. This will also persist in permissions.json if the player is authenticated to XBL. If permissions.json is missing it will be created.

changesetting <setting> <value> Changes a server setting without having to restart the server. Currently only two settings are supported to be changed, allow-cheats (true or false) and difficulty (0, peaceful, 1, easy, 2, normal, 3 or hard). They do not modify the value that's specified in


The server supports taking backups of the world files while the server is running. It's not particularly friendly for taking manual backups, but works better when automated. The backup (from the servers perspective) consists of three commands.

Command Description
save hold This will ask the server to prepare for a backup. It’s asynchronous and will return immediately.
save query After calling save hold you should call this command repeatedly to see if the preparation has finished. When it returns a success it will return a file list (with lengths for each file) of the files you need to copy. The server will not pause while this is happening, so some files can be modified while the backup is taking place. As long as you only copy the files in the given file list and truncate the copied files to the specified lengths, then the backup should be valid.
save resume When you’re finished with copying the files you should call this to tell the server that it’s okay to remove old files again.
