minio_mcp
A FastMCP-based server that enables uploading text and base64-encoded content to MinIO object storage through an HTTP transport. It supports automated bucket management and secure file path generation to streamline remote storage operations.
README
FastMCP + MinIO 上传服务(STDIO)
这是一个基于 FastMCP 的 MCP 服务,使用 STDIO 方式对外提供工具,并把内容上传到 MinIO。
1. 安装依赖
pip install -r requirements.txt
2. 配置环境变量
复制 .env.example 并按实际环境修改:
# Windows (cmd)
copy .env.example .env
主要配置项:
MINIO_ENDPOINT:例如127.0.0.1:9000MINIO_ACCESS_KEYMINIO_SECRET_KEYMINIO_SECURE:true/falseMINIO_DEFAULT_BUCKET:默认 bucketMINIO_AUTO_CREATE_BUCKET:bucket 不存在时是否自动创建MINIO_OBJECT_PREFIX:对象路径前缀(默认uploads)MCP_HOST:默认0.0.0.0MCP_PORT:默认8000
3. 本地启动(调试)
python server.py
服务将以 FastMCP STDIO transport 启动。
4. 打包与安装(给其他服务器)
本项目已提供 Python 打包文件 pyproject.toml,并暴露命令入口:minio-mcp。
4.1 从 GitHub 安装(推荐)
注意:必须使用
git+前缀,否则会出现 cannot detect archive format。
pip install "git+https://github.com/ClearMind1/minio_mcp.git"
指定分支或标签:
pip install "git+https://github.com/ClearMind1/minio_mcp.git@main"
# 或
pip install "git+https://github.com/ClearMind1/minio_mcp.git@v0.1.0"
4.2 全局工具化安装(可选)
pipx install "git+https://github.com/ClearMind1/minio_mcp.git"
# 或
uv tool install "git+https://github.com/ClearMind1/minio_mcp.git"
安装后验证命令:
# Windows
where minio-mcp
# Linux / macOS
which minio-mcp
5. 可用工具
upload_base64_to_minio
上传 base64 编码内容到 MinIO。
参数:
file_namecontent_base64bucket(可选)object_name(可选,传入则覆盖自动生成策略)content_type(可选,默认application/octet-stream)
upload_file_to_minio
上传本地文件到 MinIO。
参数:
file_path:本地文件路径(必填)file_name(可选,默认取file_path的文件名)bucket(可选)object_name(可选,传入则覆盖自动生成策略)content_type(可选,默认自动按文件名猜测,失败则application/octet-stream)
默认对象路径策略(防重名)
未传 object_name 时,服务自动生成对象路径:
{MINIO_OBJECT_PREFIX}/YYYY/MM/DD/{uuid}_{safe_filename}
示例:
uploads/2026/02/10/6c0ecb7d3e4f4d24a7f6f512a8d57f4f_hello.txt

7. MCP 客户端配置示例(stdio)
{
"mcpServers": {
"minio": {
"type": "stdio",
"command": "minio-mcp",
"args": [],
"env": {
"MINIO_ENDPOINT": "127.0.0.1:9000",
"MINIO_ACCESS_KEY": "your-access-key",
"MINIO_SECRET_KEY": "your-secret-key",

"MINIO_REGION": "us-east-1",
"MINIO_DEFAULT_BUCKET": "your-bucket"
},
"disabled": false,
"alwaysAllow": []
}
}
}
如果不使用全局命令,也可以直接用 Python 启动:
{
"mcpServers": {
"minio": {
"type": "stdio",
"command": "python",
"args": ["server.py"],
"cwd": "d:/code/MCP/minio_mcp",
"disabled": false,
