Understanding the Config
This page covers basic information about the Geyser config and what each option does. Though they are explained in the configuration itself, this explains what each option does in more detail.
The options for Geyser on the bedrock-facing end. Mostly contains options for how bedrock edition will see the server.
address: The address of Geyser on the bedrock end. In most all scenarios, this should not need to be changed.
port: The port Geyser will run on. By default, it is 19132 in bedrock.
clone-remote-port: Some hosting services change your Java port everytime you start the server and require the same port to be used for Bedrock/UDP connections. This option makes the Bedrock port the same as the Java port every time you start the server. This option does not do anything on the Standalone version of Geyser.
motd1: The first line of the MOTD for Geyser.
motd2: The second line of the MOTD for Geyser. Please keep in mind, this option will only work if Geyser is shown in the Friends tab!
server-name: The world name that is shown in the top-right area of the pause screen.
Options for the remote (java) server.
address: The address of the Minecraft: Java Edition server you want to join. By default, this value is auto. By keeping it as auto, the address, port, and Floodgate support will be automatically configured. In standalone, keeping this as auto sets the remote address to 127.0.0.1.
port: The port of the Minecraft: Java Edition server you specified in the address section.
auth-type: The authentication type of the Minecraft: Java Edition server. Valid options are online, offline, and floodgate.
Please keep in mind, what you specify in the Geyser auth-type option MUST be the same as what the remote server has (with the exception of Geyser being in online mode and remote being in offline mode). You simply cannot join an online mode server without a genuine account. If you want to allow Minecraft: Bedrock Edition accounts to join without a Minecraft: Java Edition account, see the Floodgate page.
General Geyser options that are mostly specific to Geyser itself.
floodgate-key-file: The key file path for Floodgate. Requires that you have Floodgate installed and the auth-type set to floodgate.
userAuths: A section where you can put the authentication information for your Minecraft: Java Edition account for immediate login when joining Geyser. It is advised you ONLY use this option if you are running Geyser locally and that ONLY you have access to the config as it requires you put your Minecraft: Java Edition credentials in plain text!
If your Xbox account name was Notch, your Java email was foobar2000@gmail.com and your password was hunter2, you would fill this into the config:
userAuths:
Notch: # MCPE/Xbox username
email: foobar2000@gmail.com
password: "hunter2"
Put two spaces before the username and four spaces before the email and password.
command-suggestions: Bedrock clients freeze or crash when opening up the command prompt for the first time with a large amount of command suggestions. This config option disables command suggestions being sent to prevent any freezing. Since 1.16.100: command freezing and crashing has been largely reduced; you may no longer need this option enabled.
passthrough-motd: If the MOTD should be relayed from the remote server. Causes the motd1 and motd2 options in the bedrock section to no longer have a use.
passthrough-protocol-name: Relay the protocol name (e.g. BungeeCord [X.X], Paper 1.X) - this is only really useful when using a custom protocol name! This will also show up on sites like MCSrvStatus. <mcsrvstat.us>
passthrough-players: If the current and max player counts should be relayed from the remote server.
legacy-ping-passthrough: If enabled, manually pings the server by impersonating a Minecraft client instead of using the server's API. This option should only be enabled if your MOTD or player count is not accurate, as it can cause errors especially on BungeeCord. This option does nothing on standalone.
ping-passthrough-interval: How often the fake Minecraft client should attempt to ping the remote server to update information, in seconds (a setting of 1 will ping the server every second; a setting of 3 will ping the server every three seconds). Only relevant for standalone and legacy ping passthrough. Increase the number if you're getting timeout or BrokenPipe exceptions.
max-players: The maximum amount of players shown when pinging the server. This does not actually cap how many players can join the Geyser instance at this time. The number will visually increase when pinging if the amount of players is greater, as Bedrock clients will not even attempt to join a full server.
debug-mode: If debug messages should be printed in console. Useful if you run into an error and need more context.
general-thread-pool: The amount of threads Geyser will be able to use. Higher is not always better :P.
allow-third-party-capes: If third party (Optifine, 5zig, LabyMod, etc.) capes should be displayed to the bedrock player.
allow-third-party-ears: If third party Deadmau5-style ears should be enabled. Currently only supports MinecraftCapes.
show-cooldown: Bedrock Edition currently does not have Java Edition 1.9+ combat mechanics. In order to get around this, Geyser sends a fake cooldown by sending a title message. This cooldown should not show if 1.8 combat mechanics are in use.
default-locale: The default locale to send to players if their locale could not be found. Check this page to find the code corresponding to your language.
chunk-caching: Cache chunks for each Bedrock player, adds support for additional sounds and fixing movement issues at the expense of slightly more RAM usage. This option is always on for Spigot as we can use the server's API to get block information at no expense.
cache-images: Specify how many days images will be cached to disk to save downloading them from the internet. A value of 0 is disabled. (Default: 0)
allow-custom-skulls: Allows custom skulls to be displayed when placed. Keeping them enabled may cause a performance decrease on older/weaker devices.
above-nether-bedrock-building: Bedrock prevents building and displaying blocks above Y127 in the Nether - enabling this config option works around that by changing the Nether dimension ID to the End ID. The main downside to this is that the sky will resemble that of the End sky in the Nether, but ultimately it's the only way for this feature to work.
force-resource-packs: Force clients to load all resource packs if there are any. If set to false, it allows the user to disconnect from the server if they don't want to download the resource packs.
xbox-achievements-enabled: Allows Xbox achievements to be unlocked. This disables certain commands so the Bedrock client can't to "cheat" to get them; this cannot be worked around if you want to enable this. Commands such as /gamemode and /give will not work from Bedrock with this enabled.
scoreboard-packet-threshold: Geyser updates the Scoreboard after every Scoreboard packet, but when Geyser tries to handle a lot of scoreboard packets per second can cause serious lag. This option allows you to specify after how many Scoreboard packets per seconds the Scoreboard updates will be then limited to four updates per second.
enable-proxy-connections: Allow connections from ProxyPass and Waterdog. See https://www.spigotmc.org/wiki/firewall-guide/ for assistance - use UDP instead of TCP. This option does not need to be enabled in instances like BungeeCord or Velocity.
mtu: https://en.wikipedia.org/wiki/Maximum_transmission_unit - The internet supports a maximum MTU of 1492 but could cause issues with packet fragmentation. 1400 is the default.
use-adapters: Whether to use direct server methods to retrieve information such as block states. Turning this off for Spigot will stop NMS from being used but will have a performance impact.
