MSMP Entity

A server-side Fabric mod that extends the Minecraft Server Management Protocol (MSMP) by providing additional functions for getting and setting entity data.

This mod is designed for tooling, dashboards, automation systems, external monitoring tools, and integrations that need structured access to entity information without relying on command parsing or RCON hacks.

Installation

1. Download the mod .jar and place it in your server's mods/ folder.
2. Enable the Management Server in server.properties:

   management-server-enabled=true
   

3. Start the server. The Management Server will listen on localhost:25576 by default.

Configuration

On first start, the mod generates a configuration file at <server_root_dir>/config/msmp/entity/config.yml, where you can tune the notification system for the tracked events that use threshold/interval-based polling:

# Main configuration file for MSMP Entity.

# Configuration for position-related settings.
position:
  # Settings for notifications.
  notification:
    # Number of server ticks between position change checks for subscribed entities.
    # Lower values result in more frequent checks and potentially more notifications, but can increase server load.
    # @default: 20
    interval-ticks: 20
    # Minimum distance in blocks that an entity must move to trigger a position change notification.
    # Setting this to 0.0 will trigger a notification for any movement.
    # @default: 1.0
    block-delta: 1.0
# Configuration for rotation-related settings.
rotation:
  # Settings for notifications.
  notification:
    # Number of server ticks between rotation change checks for subscribed entities.
    # Lower values result in more frequent checks and potentially more notifications, but can increase server load.
    # @default: 20
    interval-ticks: 20
    # Minimum change in yaw or pitch, in degrees, that an entity must rotate to trigger a rotation change notification.
    # Setting this to 0.0 will trigger a notification for any rotation change.
    # @default: 10.0
    rotation-delta: 10.0

Lower interval values mean more frequent checks (and potentially more notifications), at the cost of slightly more server load. Setting a delta to 0.0 triggers a notification on any change, however small.

RPC Methods

The mod currently provides the following MSMP RPC methods. All of these methods are also automatically discoverable through the standard rpc.discover MSMP endpoint.

RPC Notifications

The mod also provides the following MSMP RPC notifications that clients can subscribe to:
