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
