腾讯云 COS MCP 服务器

一个基于 Node.js 的 Model Context Protocol (MCP)服务器,为 Claude Desktop、Cursor 和 Windsurf 等 IDE 提供腾讯云对象存储(COS)功能。

功能特性

  • 🚀 文件上传 - 支持单文件和批量文件上传到腾讯云 COS
  • 🔗 临时 URL - 生成带签名的临时访问链接,支持自定义过期时间
  • 📋 文件管理 - 列出存储桶中的对象,支持前缀过滤
  • 🗑️ 文件删除 - 安全删除 COS 中的指定对象
  • 🔧 MCP 兼容 - 完全兼容 Model Context Protocol 规范

快速开始

本地调试

# 克隆项目
git clone https://github.com/156554395/tx-cos-mcp.git
cd tx-cos-mcp

# 安装依赖
pnpm install

# 配置环境变量
export COS_SECRET_ID=your-secret-id
export COS_SECRET_KEY=your-secret-key
export COS_REGION=your-region
export COS_BUCKET=your-bucket
export COS_DOMAIN=your-custom-domain.com

# 启动调试服务器
pnpm inspector

环境配置

服务器通过环境变量读取腾讯云 COS 配置:

作为 MCP 服务器使用(推荐)

在 MCP 兼容编辑器中配置:

{
  "command": "npx",
  "args": ["-y", "tx-cos-mcp"],
  "env": {
    "COS_SECRET_ID": "your-secret-id",
    "COS_SECRET_KEY": "your-secret-key",
    "COS_REGION": "your-region",
    "COS_BUCKET": "your-bucket",
    "COS_DOMAIN": "your-custom-domain.com",
    "transportType": "stdio"
  }
}

环境变量说明

变量名 必需 说明 示例
COS_SECRET_ID 腾讯云 Secret ID AKIDxxx...
COS_SECRET_KEY 腾讯云 Secret Key xxx...

MCP 工具列表

1. upload_file - 单文件上传

{
  "file_path": "/path/to/local/file.jpg",    // 必需:本地文件路径
  "object_key": "images/file.jpg",           // 可选:COS中的对象键
  "custom_domain": "cdn.example.com"        // 可选:自定义域名
}

2. upload_multiple - 批量文件上传

{
  "files": [
    {
      "file_path": "/path/to/file1.jpg",
      "object_key": "images/file1.jpg"       // 可选
    },
    {
      "file_path": "/path/to/file2.png"      // 使用文件名作为对象键
    }
  ]
}

3. get_signed_url - 获取临时访问 URL

{
  "object_key": "images/file.jpg",          // 必需:COS对象键
  "expire_time": 3600                       // 可选:过期时间(秒),默认1小时
}

4. list_objects - 列出存储桶对象

{
  "prefix": "images/"                       // 可选:对象键前缀过滤
}

5. delete_object - 删除对象

{
  "object_key": "images/file.jpg"           // 必需:要删除的对象键
}

IDE 集成配置

使用本地运行集成

      "env": {
        "COS_SECRET_ID": "your-secret-id",
        "COS_SECRET_KEY": "your-secret-key",
        "COS_REGION": "your-region",
        "COS_BUCKET": "your-bucket",
        "COS_DOMAIN": "your-custom-domain.com"
      }
    }
  }
}
