MinIO PUT MCP 服务器

PUT-only 的 MinIO MCP 服务器 — 只上传、不查询、不删除,专为数据归档与写入场景设计。


仓库地址

https://github.com/zymeli/minio-put-mcp.git


适用场景

  • 需要将文件、数据流归档到 MinIO 存储
  • 审计合规要求:按 日期/机器/文件 三级路径自动组织存储结构
  • 杜绝误删、误读操作,服务器只开放上传权限

核心概念

每次上传的 目标路径 由三个标识串联而成:

存储桶 / <did> / <sid> / <fid>
标识 全称 说明
did Date ID 日期,yyyy-mm-dd 格式
sid Source ID 来源机器标识,32 位 MD5 hex
fid File ID 文件标识,UUID v4 格式

路径示例

my-bucket/2026-07-29/a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6/550e8400-e29b-41d4-a716-446655440000

每个文件上传后,还会自动生成一个 元数据 JSON 文件,存储在相同路径但附加 .json 后缀:

my-bucket/2026-07-29/a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6/550e8400-e29b-41d4-a716-446655440000.json

元数据文件记录了原始输入信息、上传结果和精确时间戳,便于后续审计与追踪。


帮助信息

服务启动时可通过 --help-h 参数查看完整的帮助说明:

node build/index.js --help

帮助信息包含所有启动参数说明、工具列表、返回值格式和示例,输出到 stderr。


安装

# 克隆项目后安装依赖
git clone https://github.com/zymeli/minio-put-mcp.git
cd minio-put-mcp
npm install

# 编译
npm run build

启动参数

node build/index.js \
  --endpoint=192.168.1.100 \
  --port=9000 \
  --access-key=YOUR_ACCESS_KEY \
  --secret-key=YOUR_SECRET_KEY \
  [--use-ssl=false] \
  [--region=us-east-1] \
  [--did=2026-07-29] \
  [--sid=abc123...] \
  [--fid=550e8400-...]
参数 必需 说明
--endpoint MinIO 服务器地址
--port 端口,默认 9000
--access-key 访问密钥
--secret-key 秘密密钥
--use-ssl 是否使用 SSL,默认 false
--region 区域设置
--did 日期 yyyy-mm-dd,未指定时用当天日期
--sid 32 位 MD5 hex,未指定时根据本机硬件指纹自动生成
--fid UUID 格式,未指定时随机生成(单文件模式优先使用)

SID 自动生成规则

当不指定 --sid 时,服务器启动时自动收集本机以下信息:

  1. 主机名(os.hostname()
  2. 所有非零网络接口 MAC 地址

将以上信息拼接后取 MD5,生成 32 位 hex 作为默认识别 ID。同一台机器多次启动结果一致。


MCP 工具

1. put_file — 上传单个文件

输入参数:

{
  "bucketName": "my-bucket",
  "filePath": "D:\\report.pdf",
  "metadata": { "department": "finance" }
}

执行效果:

  • 自动生成目标路径 did/sid/fid
  • 上传文件本体
  • 上传元数据 JSON(含 etag、时间戳等)

2. put_files — 批量上传文件

输入参数:

{
  "bucketName": "my-bucket",
  "files": [
    { "filePath": "D:\\photo1.jpg", "metadata": { "tag": "travel" } },
    { "filePath": "D:\\photo2.jpg" }
  ]
}

执行效果:

  • 共享同一 didsid
  • 每个文件独立生成 fid
  • 逐个上传,失败不影响后续文件

3. put_stream — 流式上传(从 URL 源)

输入参数:

{
  "bucketName": "my-bucket",
  "sourceUrl": "https://example.com/large-audio.mp3",
  "contentType": "audio/mpeg",
  "metadata": { "description": "会议录音" }
}

执行效果:

  • sourceUrl 获取数据,流式直传 MinIO
  • 数据不落盘、不占用内存,适合音视频等大文件
  • 自动从 HTTP 响应头推导 content-type

返回值

所有 MCP 工具执行完成后,返回值即是上传到 MinIO 的元数据 JSON 文件内容, 与服务器上 <did>/<sid>/<fid>.json 中存储的数据完全一致。

工具 返回格式
put_file 单个元数据 JSON 对象
put_stream 单个元数据 JSON 对象
put_files 元数据 JSON 对象数组
