Beilin Entry Control
by Narek239
Beilin Entry Control is a server-side Fabric mod that checks each joining player against the Beiyue API before they can enter a Beiyue member server.
What it does
On a server running the mod, a player's access is validated by contacting the Beiyue API at beiyue.us. Players without permission, or who have an active restriction, are denied entry. Ban and permission changes are pushed to the server in real time over a WebSocket connection, so updates do not wait for a restart.
The mod is meant for Beiyue member servers and needs a valid Beiyue API key to operate. It requires Fabric API on a Fabric server. Only the server needs it: players join without installing anything. Its memory-only operations leave no persistent side effects and do not modify other mods or game files. It is released under the MIT License and is open source, with public links to the source code and issue tracker.
Other mods can build on the same access layer. Beilin Data Portability is one catalog mod that requires Beilin Entry Control and uses its Beiyue API and WebSocket connection. Files exist for Fabric only, across 25 release versions, 1.19.2 – 26.2.
Key features
Unified access control
All player entry decisions go through one check against the Beiyue API, so the same rules apply across the member servers.
Real-time ban updates
Permission and ban changes reach the server over a WebSocket, so restrictions take effect without waiting for a reload.
Entry denial for restricted players
A player without permission, or under an active restriction, is refused entry at the point of joining.
No lasting changes to the game
Operations run in memory and leave no persistent side effects, and other mods and game files are left untouched.

Use cases
Beiyue member servers
Server owners in the Beiyue network use the mod to gate who may join, with bans applied as they are issued.
Linked data tools
Companion mods such as Beilin Data Portability build on the same API and WebSocket connection to exchange player data.
Who it’s for: The mod suits server owners who run a Beiyue member server on Fabric and hold a valid Beiyue API key. It has no use on single-player worlds or servers outside the Beiyue network.
