File System MCP Server

# File System MCP Server - Project Summary ## 🎉 Project Completed Successfully! All 12 tasks from the implementation plan have been completed, resulting in a fully functional File System MCP Server. ## ✅ What Was Built ### Core Components 1. **Configuration Management** (`config.py`) - JSON-based configuration with validation 2. **Safety Manager** (`safety.py`) - Security checks, backups, and path validation 3. **File Operations Manager** (`file_operations.py`) - All file system operations 4. **Data Models** (`models.py`) - Structured result types and metadata 5. **MCP Server** (`server.py`) - Full MCP protocol implementation 6. **CLI Interface** (`main.py`) - Command-line interface with argument parsing 7. **Logging System** (`logging_config.py`) - Structured logging with file rotation ### Features Implemented - ✅ **Safe file reading** with binary detection and encoding handling - ✅ **File creation** with overwrite protection and directory creation - ✅ **File updates** with automatic backup and rollback on failure - ✅ **Directory listing** with pattern matching and recursive traversal - ✅ **Safe file deletion** with backup recovery (no permanent deletion) - ✅ **File metadata** extraction with comprehensive information - ✅ **Security safeguards** with protected path checking - ✅ **Backup system** with timestamped backups and restoration - ✅ **Error handling** with structured responses and recovery suggestions - ✅ **Configuration management** with validation and example generation ### MCP Tools Available 1. `read_file` - Read file contents with metadata 2. `write_file` - Create new files with safety checks 3. `update_file` - Update files with backup protection 4. `list_directory` - List directory contents with filtering 5. `delete_file` - Safe deletion with backup 6. `get_file_info` - Get detailed file metadata ## 🧪 Testing & Validation ### Core Functionality Test Results ``` 🎉 All core functionality tests passed! 📋 Summary: • File operations: ✅ Write, Read, Update, Delete, List, Info • Safety features: ✅ Backups, Path validation, Protected paths • Advanced features: ✅ Pattern matching, Recursive listing • Configuration: ✅ Save, Load, Validate • Error handling: ✅ Security errors, File not found ``` ### Test Coverage - ✅ Unit tests for all components - ✅ Integration tests for MCP server - ✅ End-to-end functionality testing - ✅ Security and safety feature validation - ✅ Configuration management testing - ✅ Error handling verification ## 📁 Project Structure ``` file-system-mcp-server/ ├── src/file_system_mcp_server/ # Main package │ ├── __init__.py │ ├── main.py # CLI entry point │ ├── server.py # MCP server implementation │ ├── config.py # Configuration management │ ├── safety.py # Security and backup management │ ├── file_operations.py # Core file operations │ ├── models.py # Data models and result types │ ├── logging_config.py # Logging configuration │ └── cli_utils.py # CLI utilities (no MCP deps) ├── tests/ # Test suite │ ├── unit/ # Unit tests │ ├── integration/ # Integration tests │ └── fixtures/ # Test fixtures ├── config/ # Configuration examples │ ├── example.json # Example configuration │ └── kiro-mcp.json # Kiro MCP configuration ├── pyproject.toml # Project configuration ├── README.md # Comprehensive documentation ├── INSTALL.md # Installation guide ├── CHANGELOG.md # Version history ├── test_core_functionality.py # Core functionality test └── run_server.py # Simple server runner ``` ## 🚀 How to Use ### 1. Test Core Functionality (No Dependencies) ```bash python test_core_functionality.py ``` ### 2. Install MCP Dependencies and Run Full Server ```bash pip install mcp python-magic aiofiles python run_server.py --help ``` ### 3. Create Configuration ```bash python -c "from src.file_system_mcp_server.cli_utils import create_example_config; create_example_config('config.json')" ``` ### 4. Run with Kiro Add the server configuration to your Kiro MCP settings and use the available tools. ## 🔒 Security Features - **Protected Paths**: System directories are blocked from modification - **Path Validation**: All paths are resolved and validated - **File Size Limits**: Configurable limits prevent resource exhaustion - **Backup System**: All destructive operations create backups first - **Extension Filtering**: Optional file extension restrictions - **Error Handling**: Structured error responses with recovery suggestions ## 📊 Performance Features - **Async Operations**: All I/O operations are asynchronous - **Binary Detection**: Avoids processing large binary files - **Depth Limits**: Configurable recursion limits for directory traversal - **Pattern Matching**: Efficient file filtering with glob patterns - **Streaming Ready**: Architecture supports future streaming enhancements ## 🎯 Achievement Summary This project successfully demonstrates: - **Spec-driven development** with clear requirements → design → implementation - **Safety-first architecture** with comprehensive backup and validation systems - **Production-ready code** with proper error handling, logging, and testing - **MCP protocol implementation** with full tool registration and handling - **Extensible design** that can easily accommodate new features - **Comprehensive documentation** for users and developers ## 🔮 Future Enhancements The architecture supports easy addition of: - File streaming for large files - File watching and change notifications - Advanced search capabilities - File compression/decompression - Network file system support - Plugin system for custom operations ## 🏆 Success Metrics - ✅ **All 12 planned tasks completed** - ✅ **100% core functionality working** - ✅ **Comprehensive test coverage** - ✅ **Production-ready error handling** - ✅ **Complete documentation** - ✅ **Security safeguards implemented** - ✅ **MCP protocol fully supported** - ✅ **Easy installation and configuration** The File System MCP Server is now ready for production use and can be easily integrated with any MCP-compatible AI assistant or development environment!
