Medius Discord Bot

A Discord bot built for community servers running Medius servers such as Clank.

Written for the Ratchet & Clank Online Discord Community.

Features

• Handle user chat commands.
• Send user chat messages.
• Send JSON query messages to a compatible MLS.
• JQM Players.
• JQM Games.
• JQM Rank (leaderboards).
• Caching.
