Create multiple new relations between entities. Each endpoint (from/to) can be specified by id OR by name/type. Returns relations with their assigned IDs. Use override=true to update existing relations.

Add new observations to existing entities. Entity can be specified by entityId OR by entityName/entityType. Returns observation IDs. Constraint: observations unique by (entity, observationType, source). Use override=true to update existing observations.

Delete entities and their relations. Specify each entity by id OR by name/entityType.

Delete specific observations. Specify by observation id OR by entity identifier + observationType + source.

Delete relations. Specify by relation id OR by entity IDs (fromId/toId/relationType) OR by entity names (from/fromType/to/toType/relationType).

Read the entire knowledge graph. Returns all entities (with IDs) and relations (with IDs).

Full-text search with BM25 ranking. Returns matching entities sorted by relevance. Supports FTS5 query syntax: simple terms (auth), phrases ("user auth"), AND/OR/NOT operators (user AND auth), prefix matching (auth*), proximity search (NEAR(user auth, 5)). Simple queries auto-convert to prefix-matching AND search.

Open specific entities. Specify each by id OR by name/entityType. Returns entities with their IDs.
