OptionalentityOptional domain taxonomy hint (entity types) injected into the extraction prompt.
OptionalextractionChat model used for per-chunk entity/relationship extraction. Defaults to the server's graph model.
Per-knowledge-base GraphRAG configuration. Opt-in and mutable (unlike
embeddingModel/vectorDbType); only honored forvectorDbType:'mongoAtlas'KBs. Enabling it on a KB that already has content backfills the graph automatically (a debounced structural build runs once the KB goes quiet); therebuildGraphendpoint remains available for an immediate or full rebuild.
