    inputSchema: {
      type: 'object',
      properties: {
        bucketName: { type: 'string', description: '存储桶名称' }

      required: ['bucketName']
    }
  }

    }).parse(args);
    
    await this.minioClient.deleteBucketPolicy(bucketName);
    return {
      content: [
        {
          type: 'text',
          text: `成功删除存储桶 ${bucketName} 的策略`
        }
      ]
    };
  }
