    try {
      const result = await shipStationClient.deactivateStore(storeId);
      return {
        content: [{ type: "text", text: JSON.stringify(result, null, 2) }]
      };
    } catch (error) {
      return {
        content: [{ type: "text", text: error.message }],
        isError: true
      };
    }
  }

      tool.name,
      tool.schema,
