Minecraft server.properties

Complete and compact explanation of all default Minecraft server.properties options with a full example.

This page explains all default options found in the server.properties file.

Keep in mind that all changes require a full server restart.

Monitoring & remote access

Key	Example	Explanation
`enable-jmx-monitoring`	`false`	Enables JMX monitoring for external monitoring tools.
`enable-rcon`	`false`	Enables remote console access (RCON).
`rcon.port`	`25575`	Port used for RCON connections.
`rcon.password`	(empty)	Password required for RCON authentication.
`broadcast-rcon-to-ops`	`true`	Broadcasts RCON commands to server operators.
`broadcast-console-to-ops`	`true`	Broadcasts console commands to server operators.

RCON should not be exposed to the public internet. The protocol transmits all data unencrypted, meaning credentials and commands can be intercepted by anyone monitoring the connection. We strongly advise against enabling RCON on public networks.

Using RCON requires a separate port. You can add a port in the panel.

Core server access & identity

Key	Example	Explanation
`server-ip`	(empty)	IP address the server binds to. Do not change in hosted environments.
`server-port`	`25565`	Main TCP port the server listens on.
`online-mode`	`true`	Requires Mojang authentication.
`prevent-proxy-connections`	`false`	Attempts to block proxy/VPN connections.
`hide-online-players`	`false`	Hides player count from server list ping.
`enable-status`	`true`	Allows server list status ping.
`motd`	`A Minecraft Server`	Message shown in the multiplayer server list.

Do not edit server-ip. Only change server-port if you understand the implications.

Query & status

Key	Example	Explanation
`enable-query`	`false`	Enables GameSpy4 query protocol.
`query.port`	`25565`	Port used for query connections.

Query requires a separate port. You can add one in the panel.

Player access & permissions

Key	Example	Explanation
`max-players`	`20`	Maximum number of concurrent players.
`white-list`	`false`	Only allows whitelisted players.
`enforce-whitelist`	`false`	Forces whitelist even for operators.
`player-idle-timeout`	`0`	Kicks idle players after X minutes (0 = disabled).
`op-permission-level`	`4`	Operator permission level (1–4).
`function-permission-level`	`2`	Permission level for functions.

Gameplay rules

Key	Example	Explanation
`gamemode`	`survival`	Default game mode for new players.

`max-tick-time`	`60000`	Max tick time before server shuts down.
`max-chained-neighbor-updates`	`1000000`	Limits redstone update chains.
`sync-chunk-writes`	`true`	Forces synchronous chunk writes.
`use-native-transport`	`true`	Uses OS-native networking for performance.
`rate-limit`	`0`	Packet rate limiting (0 = disabled).
