MMP — Maintenance Mode Plugin

Simple · Secure · Case-sensitive

A lightweight Paper plugin for Minecraft 1.21.11 that enables maintenance mode: only whitelisted players can join the server. Perfect for updates, testing, or private server maintenance.

✅ Features

• 🔒 Case-sensitive whitelist by player name
• 🚫 Instantly kicks unauthorized players when maintenance mode is enabled — including those already online
• 📝 Fully customizable messages via messages.yml — no recompilation needed
• 💬 Tab completion for /mmp remove — suggests only existing whitelist entries
• 🌐 Custom MOTD in server list — shows "Maintenance Mode" to all players
• 🔧 Hot-reload support: /mmp reload updates both config and messages without restart
• 🛡️ Permission-based commands with sensible defaults (op by default)
• 📦 Zero dependencies — works standalone on any Paper 1.21.11+ server
