+# Rust MCP Filesystem Server
+
+Rust MCP Filesystem Server is a high-performance filesystem MCP server built with Rust, providing fast and secure file operations.
+
+## Features
+
+- 🚀 **High Performance** - Rust-powered high-performance file operations
+- 🔒 **Secure Access** - Configurable access control
+- 📁 **File Operations** - File read/write, directory traversal
+- 🔍 **File Search** - Fast file searching
+- 📊 **File Info** - File metadata queries
+- ⚡ **Async I/O** - Asynchronous file I/O operations
+
+## Environment Variables
+
+| Variable                            | Default       | Description                  |
+| ----------------------------------- | ------------- | ---------------------------- |
+| `RUST_MCP_FILESYSTEM_VERSION`       | `latest`      | Docker image version         |
+| `RUST_MCP_FILESYSTEM_PORT_OVERRIDE` | `8000`        | Service port                 |
+| `ALLOWED_PATHS`                     | `/projects`   | Allowed access paths         |
+| `HOST_WORKSPACE_PATH`               | `./workspace` | Host workspace path to mount |
+| `TZ`                                | `UTC`         | Timezone                     |
+
+## Quick Start
+
+### 1. Configure Environment
+
+Create a `.env` file:
+
+```env
+RUST_MCP_FILESYSTEM_VERSION=latest
+RUST_MCP_FILESYSTEM_PORT_OVERRIDE=8000
+ALLOWED_PATHS=/projects
+HOST_WORKSPACE_PATH=/path/to/your/workspace
+TZ=Asia/Shanghai
+```
+
+### 2. Configure File Access
+
+In `docker-compose.yaml`, configure directories to access:
+
+```yaml
+volumes:
+  # Read-only access
+  - /path/to/workspace:/projects/workspace:ro
+  # Read-write access (remove :ro)
+  - /path/to/data:/projects/data
+```
+
+### 3. Start Service
+
+```bash
+docker compose up -d
+```
+
+### 4. Verify Service
+
+```bash
+curl http://localhost:8000/health
+```
+
+## Security Features
+
+The service implements multiple layers of security:
+
+1. **Read-only Filesystem**: Container filesystem set to read-only
+2. **Permission Restrictions**: Minimized container permissions
+3. **Path Restrictions**: Only configured paths can be accessed
+4. **No Privilege Escalation**: Prevents privilege escalation
+5. **Capability Restrictions**: Only necessary Linux capabilities retained
+
+## Performance Characteristics
+
+- ✅ **Zero-copy**: Leverages Rust's zero-copy features
+- ✅ **Async I/O**: High-concurrency file operations
+- ✅ **Memory Safety**: Memory safety guaranteed by Rust
+- ✅ **Low Resource Usage**: Minimum 64MB memory
+
+## Resource Requirements
+
+- Minimum memory: 64MB
+- Recommended memory: 256MB
+- CPU: 0.25-1.0 cores
+
+## Common Use Cases
+
+1. **Code Repository Access** - Allow AI to access and analyze codebases
+2. **Document Processing** - Read and process document files
+3. **Log Analysis** - Analyze log files
+4. **Configuration Management** - Read and update configuration files
+
+## Security Recommendations
+
+⚠️ **Important**: When using:
+
+1. Only mount necessary directories
+2. Prefer read-only mode (`:ro`)
+3. Do not mount sensitive system directories
+4. Regularly audit access logs
+5. Use firewall to restrict network access
+

+| Performance   | ⭐⭐⭐⭐⭐               | ⭐⭐⭐                    |
+| Memory Usage  | 64MB+               | 128MB+                 |
+| Concurrency   | Excellent           | Good                   |
+| Startup Speed | Fast                | Medium                 |
