      const response = await tasks.tasks.list({
        tasklist: "@default",
      });
  
      return {
        content: [
          {
            type: "text",
            text: JSON.stringify(response.data.items, null, 2),
          },
        ],
      };
    } catch (error) {
      throw new McpError(

      );
    }
  }
