Implementation Reference
- Handler logic that executes the search_nodes MCP tool by invoking the knowledge graph manager's searchNodes method and formatting the tool response.
case "search_nodes": const searchResults = await this.knowledgeGraphManager.searchNodes(args.query); return formatToolResponse({ data: searchResults, actionTaken: `Searched nodes with query: ${args.query}` }); - Schema definition and tool metadata (name, description, inputSchema) for the search_nodes tool.
name: "search_nodes", description: "Search for nodes in the knowledge graph based on a query", inputSchema: { type: "object", properties: { query: { type: "string", description: "The search query to match against node names, types, and metadata content" }, }, required: ["query"], }, }, - src/integration/tools/handlers/ToolHandlerFactory.ts:46-47 (registration)Routes calls to the search_nodes tool to the appropriate SearchToolHandler instance.
if (toolName.match(/^(read_graph|search_nodes|open_nodes)$/)) { return this.searchHandler; - src/integration/tools/registry/staticTools.ts:177-217 (registration)Exports the searchTools array which includes the search_nodes tool definition for static tool registration.
export const searchTools: Tool[] = [ { name: "read_graph", description: "Read the entire knowledge graph", inputSchema: { type: "object", properties: {}, }, }, { name: "search_nodes", description: "Search for nodes in the knowledge graph based on a query", inputSchema: { type: "object", properties: { query: { type: "string", description: "The search query to match against node names, types, and metadata content" }, }, required: ["query"], }, }, { name: "open_nodes", description: "Open specific nodes in the knowledge graph by their names", inputSchema: { type: "object", properties: { names: { type: "array", items: {type: "string", description: "Node name to open"}, description: "An array of node names to retrieve", }, }, required: ["names"], }, } ];
