@mosaicstack/mosaic

CLI package for the Mosaic self-hosted AI agent platform.

mosaic wizard           # First-run setup wizard
mosaic gateway install  # Install the gateway daemon
mosaic config show      # View current configuration
mosaic config hooks list  # Manage Claude hooks

Headless / CI Installation

Set MOSAIC_ASSUME_YES=1 (or ensure stdin is not a TTY) to skip all interactive prompts. The following environment variables control the install:

Gateway configuration (mosaic gateway install)

Variable	Default	Required
MOSAIC_STORAGE_TIER	local	No
MOSAIC_GATEWAY_PORT	14242	No
MOSAIC_DATABASE_URL	(none)	Yes if tier=team
MOSAIC_VALKEY_URL	(none)	Yes if tier=team
MOSAIC_ANTHROPIC_API_KEY	(none)	No
MOSAIC_CORS_ORIGIN	http://localhost:3000	No

Admin user bootstrap

Variable	Default	Required
MOSAIC_ADMIN_NAME	(none)	Yes (headless)
MOSAIC_ADMIN_EMAIL	(none)	Yes (headless)
MOSAIC_ADMIN_PASSWORD	(none)	Yes (headless)

MOSAIC_ADMIN_PASSWORD must be at least 8 characters. In headless mode a missing or too-short password causes a non-zero exit.

Example: Docker / CI install

export MOSAIC_ASSUME_YES=1
export MOSAIC_ADMIN_NAME="Admin"
export MOSAIC_ADMIN_EMAIL="admin@example.com"
export MOSAIC_ADMIN_PASSWORD="securepass123"

mosaic gateway install

Hooks management

After running mosaic wizard, Claude hooks are installed in ~/.claude/hooks-config.json.

mosaic config hooks list              # Show all hooks and enabled/disabled status
mosaic config hooks disable PostToolUse  # Disable a hook (reversible)
mosaic config hooks enable PostToolUse   # Re-enable a disabled hook

Set CLAUDE_HOME to override the default ~/.claude directory.
