Implementation Reference
- src/index.ts:122-130 (handler)Core handler function in KnowledgeGraphManager that loads the graph, filters out the specified relations, and saves the updated graph to persist the deletions.
async deleteRelations(relations: Relation[]): Promise<void> { const graph = await this.loadGraph(); graph.relations = graph.relations.filter(r => !relations.some(delRelation => r.from === delRelation.from && r.to === delRelation.to && r.relationType === delRelation.relationType )); await this.saveGraph(graph); } - src/index.ts:315-337 (registration)Tool registration in the ListToolsRequestHandler, defining the name, description, and input schema for the delete_relations tool.
{ name: "delete_relations", description: "Delete multiple relations from the knowledge graph", inputSchema: { type: "object", properties: { relations: { type: "array", items: { type: "object", properties: { from: { type: "string", description: "The name of the entity where the relation starts" }, to: { type: "string", description: "The name of the entity where the relation ends" }, relationType: { type: "string", description: "The type of the relation" }, }, required: ["from", "to", "relationType"], }, description: "An array of relations to delete" }, }, required: ["relations"], }, }, - src/index.ts:396-398 (handler)Dispatch logic in the CallToolRequestHandler that calls the KnowledgeGraphManager.deleteRelations method with the provided arguments and returns a success message.
case "delete_relations": await knowledgeGraphManager.deleteRelations(args.relations as Relation[]); return { content: [{ type: "text", text: "Relations deleted successfully" }] }; - src/index.ts:30-34 (schema)TypeScript interface defining the structure of a Relation object used by the delete_relations tool.
interface Relation { from: string; to: string; relationType: string; }
