  execute: async (_args, { log }) => {
    const memoryPath = process.env.MEMORY_PATH || path.join(os.homedir(), '.mcp-think-tank/memory.jsonl');
    // Removed debug log
    return JSON.stringify(memoryPath);
  }

• src/utils/tools.ts:14-16 (schema)

  Zod schema defining the optional dummy input parameter for the tool.

  parameters: z.object({
    random_string: z.string().describe("Dummy parameter for no-parameter tools").optional()
  }),

    description: 'Return absolute path of the active knowledge-graph file.',
    parameters: z.object({
      random_string: z.string().describe("Dummy parameter for no-parameter tools").optional()
    }),
    execute: async (_args, { log }) => {
      const memoryPath = process.env.MEMORY_PATH || path.join(os.homedir(), '.mcp-think-tank/memory.jsonl');
      // Removed debug log
      return JSON.stringify(memoryPath);
    }
