The MinIO Model-Context Protocol (MCP) server and client provide a standardized way to interact with MinIO object storage.
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
orexit
to end the session
- Type
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.
