Implementation Reference
- index.ts:205-230 (handler)The handler function in KnowledgeGraphManager that loads the graph, updates specified entities by merging properties, increments version, updates the graph in place, saves it, and returns the updated entities.
async updateEntities(entities: Entity[]): Promise<Entity[]> { const graph = await this.loadGraph(); const updatedEntities = entities.map(updateEntity => { const existingEntity = graph.entities.find(e => e.name === updateEntity.name); if (!existingEntity) { throw new Error(`Entity with name ${updateEntity.name} not found`); } return { ...existingEntity, ...updateEntity, version: existingEntity.version + 1, createdAt: new Date().toISOString() }; }); // Update entities in the graph updatedEntities.forEach(updatedEntity => { const index = graph.entities.findIndex(e => e.name === updatedEntity.name); if (index !== -1) { graph.entities[index] = updatedEntity; } }); await this.saveGraph(graph); return updatedEntities; } - index.ts:454-479 (registration)Tool registration in the ListTools response, defining name, description, and input schema for update_entities.
