+---
+
+## 📖 Overview
+
+**RustFS MCP Server** is a high-performance [Model Context Protocol (MCP)](https://spec.modelcontextprotocol.org) server that provides AI/LLM tools with seamless access to S3-compatible object storage operations. 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

+```
+
+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"
+      }
+    }
+  }
+}
+```
+## 🛠️ Available Tools
+
+The MCP server exposes the following tools that AI assistants can use:
+
+### `list_buckets`
+List all S3 buckets accessible with the configured credentials.
+
+**Parameters:** None
+
+### `list_objects`
+List objects in an S3 bucket with optional prefix filtering.
+
+**Parameters:**
+- `bucket_name` (string): Name of the S3 bucket
+- `prefix` (string, optional): Prefix to filter objects
+
+### `upload_file`
+Upload a local file to S3 with automatic MIME type detection.
+
+**Parameters:**
+- `local_file_path` (string): Path to the local file
+- `bucket_name` (string): Target S3 bucket
+- `object_key` (string): S3 object key (destination path)
+- `content_type` (string, optional): Content type (auto-detected if not provided)
+- `storage_class` (string, optional): S3 storage class
+- `cache_control` (string, optional): Cache control header
+
+### `get_object`
+Retrieve an object from S3 with two operation modes: read content directly or download to a file.
+
+**Parameters:**
+- `bucket_name` (string): Source S3 bucket
+- `object_key` (string): S3 object key
+- `version_id` (string, optional): Version ID for versioned objects
+- `mode` (string, optional): Operation mode - "read" (default) returns content directly, "download" saves to local file
+- `local_path` (string, optional): Local file path (required when mode is "download")
+- `max_content_size` (number, optional): Maximum content size in bytes for read mode (default: 1MB)
+
+## Architecture
+
+The MCP server is built with a modular architecture:
+
+```

+RustFS MCP Server - Model Context Protocol server for S3 operations
+
+This server provides S3 operations through the Model Context Protocol (MCP),

+
+ENVIRONMENT VARIABLES:
+  All command-line options can also be set via environment variables.
+  Command-line arguments take precedence over environment variables.
+
+EXAMPLES:
+  # Using command-line arguments
+  rustfs-mcp-server --access-key-id your_key --secret-access-key your_secret
+
+  # Using environment variables
+  export AWS_ACCESS_KEY_ID=your_key
+  export AWS_SECRET_ACCESS_KEY=your_secret
+  rustfs-mcp-server
+
+  # Mixed usage (command-line overrides environment)
+  export AWS_REGION=us-east-1
+  rustfs-mcp-server --access-key-id mykey --secret-access-key mysecret --endpoint-url http://localhost:9000
