Implementation Reference

• src/cosService.js:745-760 (handler)

  Core implementation of the delete_object tool logic, performing the actual deletion using the Tencent COS SDK.

  async deleteObject(key) {
    this._checkConfig();
    
    try {
      const params = {
        Bucket: this.config.Bucket,
        Region: this.config.Region,
        Key: key
      };
  
      await this.cos.deleteObject(params);
      return { success: true, key };
    } catch (error) {
      throw new Error(`删除文件失败: ${error.message}`);
    }
  }

• index.js:228-241 (schema)

  Input schema and tool metadata definition for delete_object.

  delete_object: {
    name: 'delete_object',
    description: '删除COS中的对象',
    inputSchema: {
      type: 'object',
      properties: {
        object_key: {
          type: 'string',
          description: '要删除的对象键名'
        }
      },
      required: ['object_key']
    }
  },

• index.js:548-557 (handler)

  MCP CallToolRequestSchema handler dispatch for delete_object tool.

  case 'delete_object':
    const deleteResult = await cosService.deleteObject(args.object_key);
    return {
      content: [
        {
          type: 'text',
          text: JSON.stringify({ success: true, data: deleteResult }, null, 2)
        }
      ]
    };

• index.js:393-395 (registration)

  Registration of all tools (including delete_object) via ListToolsRequestSchema handler.

  server.setRequestHandler(ListToolsRequestSchema, async () => ({
    tools: Object.values(tools),
  }));
