LoginPhaseProxy

First public alpha release of LoginPhaseProxy, a Velocity plugin that proxies Minecraft Login Plugin Message/Response packets between players and backend servers.

Highlights

• Proxies LoginPluginMessagePacket from backend servers to players during login.
• Proxies LoginPluginResponsePacket from players back to backend servers.
• Helps modded backend servers that rely on login plugin communication work behind Velocity.

Compatibility

• Java: 21+
• Built against:
  • Velocity 3.5.0-SNAPSHOT build 593

Notes

This is an early alpha release. The plugin relies on Velocity internals and reflection, so it may break with Velocity changes and may contain bugs or performance issues. Test carefully before using it on a production proxy.
