MinIO 模型上下文协议（MCP）服务器

MinIO Model-Context Protocol (MCP)

This project implements a Model-Context Protocol (MCP) server and client for MinIO object storage. It provides a standardized way to interact with MinIO.

Features

Server

Resources

Exposes MinIO data through Resources. The server can access and provide:

Text files (automatically detected based on file extension)
Binary files (handled as application/octet-stream)
Bucket contents (up to 1000 objects per bucket)

Tools

ListBuckets
- Returns a list of all buckets owned by the authenticated sender of the request
- Optional parameters: start_after (pagination), max_buckets (limit results)
ListObjects
- Returns some or all (up to 1,000) of the objects in a bucket with each request
- Required parameter: bucket_name
- Optional parameters: prefix (filter by prefix), max_keys (limit results)
GetObject
- Retrieves an object from MinIO
- Required parameters: bucket_name, object_name
PutObject
- Uploads a file to MinIO bucket using fput method
- Required parameters: bucket_name, object_name, file_path

Client

The project includes multiple client implementations:

Basic Client - Simple client for direct interaction with the MinIO MCP server
Anthropic Client - Integration with Anthropic's Claude models for AI-powered interactions with MinIO

Installation

Clone the repository:

git clone https://github.com/yourusername/minio-mcp.git
cd minio-mcp

Install dependencies using pip:

pip install -r requirements.txt

Or using uv:

uv pip install -r requirements.txt

Environment Configuration

Create a .env file in the root directory with the following configuration:

# MinIO Configuration
MINIO_ENDPOINT=play.min.io
MINIO_ACCESS_KEY=your_access_key
MINIO_SECRET_KEY=your_secret_key
MINIO_SECURE=true
MINIO_MAX_BUCKETS=5

# Server Configuration
SERVER_HOST=0.0.0.0
SERVER_PORT=8000

# For Anthropic Client (if using)
ANTHROPIC_API_KEY=your_anthropic_api_key

Usage

Running the Server

The server can be run directly:

python src/minio_mcp_server/server.py

Using the Basic Client

from src.client import main
import asyncio

asyncio.run(main())

Using the Anthropic Client

Configure the servers in src/client/servers_config.json:

{
  "mcpServers": {
    "minio_service": {
      "command": "python",
      "args": ["path/to/minio_mcp_server/server.py"]
    }
  }
}

Run the client:

python src/client/mcp_anthropic_client.py

Interact with the assistant:
- The assistant will automatically detect available tools
- You can ask questions about your MinIO data
- The assistant will use the appropriate tools to retrieve information
Exit the session:
- Type quit or exit to end the session

Integration with Claude Desktop

You can integrate this MCP server with Claude Desktop:

Configuration

On MacOS: ~/Library/Application\ Support/Claude/claude_desktop_config.json
On Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "minio-mcp": {
      "command": "python",
      "args": [
        "path/to/minio-mcp/src/minio_mcp_server/server.py"
      ]
    }
  }
}

Debugging

Since MCP servers run over stdio, debugging can be challenging. For the best debugging experience, we recommend using the MCP Inspector:

npx @modelcontextprotocol/inspector python path/to/minio-mcp/src/minio_mcp_server/server.py

Upon launching, the Inspector will display a URL that you can access in your browser to begin debugging.

How are these scores calculated?

remote-capable server

The server can be hosted and run remotely because it primarily relies on remote services or has no dependency on the local environment.

提供与 MinIO 对象存储交互的标准化方式，允许访问文本文件、二进制文件和存储桶内容，同时支持列出存储桶/对象、检索对象和上传文件等操作。
