Force AegisAC

Require the AegisAC client mod to play on your server. Players who join without it get kicked.

Features

• Hard requirement — joining without AegisAC gets you kicked, cleanly.
• Configurable — set the grace period, customise the kick message (colour codes + line breaks), toggle console logging.
• Bypass permission — forceaegisac.bypass lets staff or trusted clients skip the check.
• Lightweight — no dependencies, no database, tiny jar. Stable APIs only.

Compatibility

• Minecraft 1.21.1 → latest — one jar for all of it, no per-version downloads.
• Paper and its forks (Purpur, Pufferfish, Folia-family, etc.). Works on Spigot too, though kick-message formatting is nicer on Paper.
