Implementation Reference

• src/integration/tools/handlers/SearchToolHandler.ts:20-25 (handler)

  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}`
      });

• src/integration/tools/registry/staticTools.ts:188-200 (schema)

  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"],
          },
      }
