Implementation Reference
- index.ts:638-643 (handler)The core handler function in KnowledgeGraphManager that executes the delete_entities tool logic: loads the graph, removes specified entities and their connected relations, then saves the updated graph.
async deleteEntities(entityNames: string[]): Promise<void> { const graph = await this.loadGraph(); graph.entities = graph.entities.filter(e => !entityNames.includes(e.name)); graph.relations = graph.relations.filter(r => !entityNames.includes(r.from) && !entityNames.includes(r.to)); await this.saveGraph(graph); } - index.ts:1002-1012 (schema)Input schema definition for the delete_entities tool, specifying an object with a required 'entityNames' array of strings.
inputSchema: { type: "object", properties: { entityNames: { type: "array", items: { type: "string" }, description: "An array of entity names to delete" }, }, required: ["entityNames"], }, - index.ts:1000-1013 (registration)Tool registration in the ListTools response, defining name, description, and input schema for delete_entities.
