Configuration
| Variable | Required | Secret | Description |
|---|---|---|---|
| ANTHROPIC_API_KEY | yes | yes | Anthropic API key. Required for the tools that call a model — `query` composes a cited natural-language answer, and the semantic half of `lint` reasons over claim pairs. The accessors that only read the store (`particle_show`, `particles_list`, `subjects_*`, `events_*`, `graph_view`, `quality_report`) work without it. |
| DATABASE_URL | — | — | SQLAlchemy URL of the belief store to serve. Defaults to `sqlite+aiosqlite:///./particles.db` in the working directory. |
| PARTICLES_CONFIG | — | — | Path to a `config.yaml` holding the rest of the engine's settings — additional stores, model selection per purpose, and the `mcp.write.enabled_stores` allowlist that turns the write tools on. |
