Player commands
Anyone in the server can use these: register, profile, stats, progress, match history, duos, achievements, matchup and the leaderboard view. They reply privately so they do not clutter the channel.
Admin commands
These need Manage Server: setup, channel choices, rank roles, notification types, and forcing a sync. Running one without permission returns an error rather than doing nothing.
Finding one
The commands page on this site lists everything with a search box — including admin commands you may not have permission to run yet.
