Implementation Reference
- The core handler logic for the 'add_nodes' tool within the GraphToolHandler's handleTool method. It extracts nodes from args, calls knowledgeGraphManager.addNodes, and returns a formatted success response with the added nodes.case "add_nodes": const addedNodes = await this.knowledgeGraphManager.addNodes(args.nodes); return formatToolResponse({ data: {nodes: addedNodes}, actionTaken: "Added nodes to knowledge graph" });
- The input schema definition and tool metadata (name, description) for the 'add_nodes' tool, exported as part of graphTools.{ name: "add_nodes", description: "Add multiple new nodes in the knowledge graph", inputSchema: { type: "object", properties: { nodes: { type: "array", description: "Array of nodes to add", items: { type: "object", description: "Node to add", properties: { name: {type: "string", description: "The name of the node"}, nodeType: {type: "string", description: "The type of the node"}, metadata: { type: "array", items: {type: "string", description: "Metadata item"}, description: "An array of metadata contents associated with the node" }, }, required: ["name", "nodeType", "metadata"], }, }, }, required: ["nodes"], }, },
- src/integration/tools/handlers/ToolHandlerFactory.ts:43-44 (registration)Registration of the GraphToolHandler for graph manipulation tools including 'add_nodes' via regex matching in ToolHandlerFactory.getHandler.if (toolName.match(/^(add|update|delete)_(nodes|edges)$/)) { return this.graphHandler;
- src/integration/tools/registry/toolsRegistry.ts:42-45 (registration)Registration of all static tools (including 'add_nodes') into the central tools Map during ToolsRegistry initialization.// Register static tools allStaticTools.forEach(tool => { this.tools.set(tool.name, tool); });
