Jade Plugin for Paper

A Paper server plugin that provides Jade server-side data to Fabric clients. When a player with the Jade mod connects, the plugin responds with entity and block information that the Jade HUD overlay displays.

Requirements

Paper 1.21.6 (26.1.2) or compatible
Fabric client with Jade mod installed

How It Works

The plugin intercepts Jade's custom network payloads using Paper's plugin messaging system. When a Fabric client joins:

Client sends jade:client_handshake with protocol version
Plugin responds with jade:server_handshake listing available data providers
Client periodically sends jade:request_entity / jade:request_block
Plugin queries the server world and responds with jade:receive_data (NBT format)
