JoBot is configured entirely through environment variables set in your docker-compose.yml or .env file. Required variables must be provided before the bot starts — the bot will fail to connect to Discord, Anthropic, or your Subsonic server if any of them are missing.

​
Required variables

VariableDescription
Anthropic__TokenYour Anthropic API key. Used to authenticate all Claude AI requests.
Discord__TokenYour Discord bot token from the Discord Developer Portal.
Lavalink__PassphraseThe passphrase securing your Lavalink server. You set this value; it must match LAVALINK_SERVER_PASSWORD in the Lavalink container.
ConnectionStrings__JoBotSQLite connection string. Mount a persistent volume and point this at it, e.g. Data Source=/app/config/jobot.db.
VariableDefaultDescription
Lavalink__BaseAddresshttp://lavalink:2333Internal address of the Lavalink container. Change this if you rename the service or run Lavalink on a different host/port.

​
Optional — AI tuning

VariableDefaultDescription
Ai__Modelclaude-sonnet-4-6Anthropic model slug to use for all AI responses. Accepts any valid Anthropic model ID.
Ai__MaxTokens4096Maximum number of tokens in a single Claude response.
Ai__Temperature0.7Global default creativity level (0.0 = deterministic, 1.0 = most creative).
Ai__MaxToolIterations50Maximum number of tool calls Claude can chain in a single message turn. Lower values reduce API costs.
Ai__MaxHistoryMessages40Global cap on conversation history messages sent to Claude per request.

​
Optional — Guild defaults

GuildDefaults__AiTemperature0.7Default AI temperature for guilds that have not customized their setting.
GuildDefaults__MusicVolume0.5Default music volume for guilds that have not customized their setting (0.0–1.0, where 0.5 = 50%).

​
Optional — Subsonic

VariableDefaultDescription

Subsonic__Username(none)Username for your Subsonic server.

​
Optional — ElevenLabs / TTS

Guild-level settings — AI temperature, music volume, and history length — can be changed at runtime using /settings slash commands without restarting the bot. Environment variables serve as the global defaults that apply to any guild that has not overridden them.
