Implementation Reference
- Executes the 'add_metadata' tool logic by invoking the knowledge graph manager's addMetadata method and formatting the successful response.
case "add_metadata": const addResult = await this.knowledgeGraphManager.addMetadata(args.metadata); return formatToolResponse({ data: {metadata: addResult}, actionTaken: "Added metadata to nodes" }); - Defines the input schema for validating arguments to the 'add_metadata' tool, expecting an array of metadata objects with nodeName and contents.
inputSchema: { type: "object", properties: { metadata: { type: "array", description: "Array of metadata to add", items: { type: "object", description: "Metadata to add", properties: { nodeName: {type: "string", description: "The name of the node to add the metadata to"}, contents: { type: "array", items: {type: "string", description: "Metadata content item"}, description: "An array of metadata contents to add" }, }, required: ["nodeName", "contents"], }, }, }, required: ["metadata"], }, - src/integration/tools/registry/staticTools.ts:223-249 (registration)Registers the 'add_metadata' tool in the metadataTools array, including name, description, and input schema.
