LeavePulse Agent
by LeavePulse
Servers that run LeavePulse Agent report telemetry and sync whitelist data with the LeavePulse service.
What it does
On a server, the agent sends periodic metrics such as online players, maximum players, MOTD, favicon and server and version information. It also pushes real-time updates for join, leave and other activity events, and reports server telemetry with privacy in mind.
Whitelist configuration entries are synced from LeavePulse, and the server can enforce access in either kick or restrict mode. Staff handle whitelist applications in-game and approve or deny them, while players link their Minecraft account with a verification code shown in the game. The agent also supports stable, beta and dev update channels. It works alongside plugins that track playtime and expose placeholders for chat, scoreboards and other integrations. Files are published for Fabric and NeoForge, for 22 release versions 1.20 – 26.1.2, under the GNU Affero General Public License v3.0 only, which is not open source.
