This one needs environment variables set before it will start: DATABASE_URL (PostgreSQL/Neon connection string for YOUR Mosaic knowledge graph (must end /mosaic_db). Bring your own database — no shared instance is provided.), MOSAIC_API_KEY (API key unlocking the 7 Pro tools (optional; the 5 free tools work without it)), MOSAIC_TIER (Override tier for local dev: free (default), pro, or enterprise). The author declared them in the registry entry; get the values from the project itself.
