Built with Rust for maximum performance and safety, it enables AI assistants like Claude Desktop to interact with cloud storage through a standardized protocol.
+
+### What is MCP?
+
+The Model Context Protocol is an open standard that enables secure, controlled connections between AI applications and external systems. This server acts as a bridge between AI tools and S3-compatible storage services, providing structured access to file operations while maintaining security and observability.
+
+## ✨ Features
+
+### Supported S3 Operations
+
+- **List Buckets**: List all accessible S3 buckets
+- **List Objects**: Browse bucket contents with optional prefix filtering
+- **Upload Files**: Upload local files with automatic MIME type detection and cache control
+- **Get Objects**: Retrieve objects from S3 storage with read or download modes
+
+## 🔧 Installation
+
+### Prerequisites
+
+- Rust 1.70+ (for building from source)
+- AWS credentials configured (via environment variables, AWS CLI, or IAM roles)
+- Access to S3-compatible storage service
+
+### Build from Source
+
+```bash
+# Clone the repository
+git clone https://github.com/rustfs/rustfs.git
+cd rustfs
+
+# Build the MCP server
+cargo build --release -p rustfs-mcp
+
+# The binary will be available at
+./target/release/rustfs-mcp
+```
+
+## ⚙️ Configuration
+
+### Environment Variables
+
+```bash
+# AWS Credentials (required)
+export AWS_ACCESS_KEY_ID=your_access_key
+export AWS_SECRET_ACCESS_KEY=your_secret_key
+export AWS_REGION=us-east-1  # Optional, defaults to us-east-1
+
+# Optional: Custom S3 endpoint (for MinIO, etc.)
+export AWS_ENDPOINT_URL=http://localhost:9000
+
+# Logging level (optional)
+export RUST_LOG=info
+```
+
+### Command Line Options
+
+```bash
+rustfs-mcp --help
+```
+
+The server supports various command-line options for customizing behavior:
+
+- `--access-key-id`: AWS Access Key ID for S3 authentication
+- `--secret-access-key`: AWS Secret Access Key for S3 authentication
+- `--region`: AWS region to use for S3 operations (default: us-east-1)
+- `--endpoint-url`: Custom S3 endpoint URL (for MinIO, LocalStack, etc.)
+- `--log-level`: Log level configuration (default: rustfs_mcp_server=info)
+
+## 🚀 Usage
+
+### Starting the Server
+
+```bash
+# Start the MCP server
+rustfs-mcp
+
+# Or with custom options
+rustfs-mcp --log-level debug --region us-west-2
+```
+
+### Integration with chat client
+
+#### Option 1: Using Command Line Arguments
+
+```json
+{
+  "mcpServers": {
+    "rustfs-mcp": {
+      "command": "/path/to/rustfs-mcp",
+      "args": [
+        "--access-key-id", "your_access_key",
+        "--secret-access-key", "your_secret_key",
+        "--region", "us-west-2",
+        "--log-level", "info"
+      ]
+    }
+  }
+}
+```
+
+#### Option 2: Using Environment Variables
+
+```json
+{
+  "mcpServers": {
+    "rustfs-mcp": {
+      "command": "/path/to/rustfs-mcp",
+      "env": {
+        "AWS_ACCESS_KEY_ID": "your_access_key",
+        "AWS_SECRET_ACCESS_KEY": "your_secret_key",
+        "AWS_REGION": "us-east-1"
+      }
+    }
+  }
+}
+```
+
+### Using MCP with Docker
+
+#### Docker image build
+
+Using MCP with docker will simply the usage of rustfs mcp. Building the docker image with below command:
+
+```
+docker build -f Dockerfile -t rustfs/rustfs-mcp ../../
+```
+
+Alternatively, if you want to build the image from the rustfs codebase root directory,run the command:
+
+```
+docker build -f crates/mcp/Dockerfile -t rustfs/rustfs-mcp .
+```
+
+#### IDE Configuration
+
+Adding the following content in IDE MCP settings:
+
+```
+{
+  "mcpServers": {
+    "rustfs-mcp": {
+      "command": "docker",
+      "args": [
+        "run",
+        "--rm",
+        "-i",
+        "-e",
+        "AWS_ACCESS_KEY_ID",
+        "-e",
+        "AWS_SECRET_ACCESS_KEY",
+        "-e",
+        "AWS_REGION",
+        "-e",
+        "AWS_ENDPOINT_URL",
+        "rustfs/rustfs-mcp"
+      ],
+      "env": {
+        "AWS_ACCESS_KEY_ID": "rustfs_access_key",
+        "AWS_SECRET_ACCESS_KEY": "rustfs_secret_key",
+        "AWS_REGION": "cn-east-1",
+        "AWS_ENDPOINT_URL": "rustfs_instance_url"
+      }
+    }
+  }
+}
+```
+
+If success, MCP configure page will show the [available tools](#️-available-tools).
+
