Setup

In your whitelisted Discord server, run /config with one or more of:

• chat_channel_id
• admin_channel_id
• whitelist_guild_id

Only Discord admins can run /config.

Account Linking

• On Discord, run slash command: /link
• The bot replies ephemerally with a one-time code
• In Minecraft, run: /bridge link <code>
• linkCodeExpirySeconds controls how long the code remains valid

Discord to Minecraft Relay

• On Discord in the configured chat channel, run: /mc <message>
• The message is relayed to Minecraft chat as [Discord] <name> message
• The same message is echoed in Discord as plain text: **name:** message
• If the Discord account is linked, name uses the linked Minecraft nickname

Leaderboard

• On Discord, run: /leaderboard <category>
• Optional page: /leaderboard <category> <page>
• Optional visibility: /leaderboard <category> <page> <visibility> where visibility is private (default) or public
• Linked players are shown with Discord mention tags (<@discordUserId>)
• Categories: playtime, deaths, player_kills, mob_kills, mined_blocks, distance_walked
• Leaderboard responses are ephemeral by default

Notes

• This is server-only. Do not install on clients.
• Discord failures are logged and do not intentionally crash server startup.
• Avoid logging secrets in command usage; redaction is enabled by default.
