# Stata-MCP Web UI - Complete Implementation ## Overview The Stata-MCP web UI for v1.6.0 has been successfully completed with comprehensive configuration management capabilities. This interface provides a modern, user-friendly way to configure Stata-MCP settings without any Stata integration (as per v1.6.0 scope). ## Features Implemented ### ✅ Core Configuration Management - **Stata CLI Path Configuration**: Validate executable paths with platform-specific suggestions - **Output Base Path Configuration**: Validate and create directories with proper permissions - **Real-time Validation**: Client-side and server-side validation with instant feedback - **Configuration Persistence**: Safe saving with automatic backup creation ### ✅ Advanced Configuration Features - **Configuration Backup**: Automatic backups created on every save - **Import/Export**: JSON format configuration import/export - **Reset to Defaults**: One-click reset with backup creation - **Configuration History**: Timestamped backups for rollback ### ✅ User Experience Enhancements - **Responsive Design**: Mobile-friendly interface that works on all devices - **Interactive Help**: Tooltips, help buttons, and contextual guidance - **Visual Feedback**: Success/error messages and loading states - **Modern UI**: Clean, professional design with gradient backgrounds ### ✅ API Endpoints - `GET /` - Welcome page with feature overview - `GET /config` - Configuration form with validation - `POST /api/validate` - Real-time field validation - `POST /api/reset` - Reset to default configuration - `GET /api/export` - Export configuration as JSON - `POST /api/import` - Import configuration from JSON ## File Structure ``` src/stata_mcp/webui/ ├── __init__.py # Enhanced Flask backend with validation ├── utils/ │ └── config_validator.py # Comprehensive validation utilities └── templates/ ├── index.html # Welcome page with feature overview ├── config.html # Enhanced configuration form ├── style.css # Modern responsive styling └── config.js # Client-side validation and interactions ``` ## Usage ### Starting the Web UI ```bash # From project root python -m stata_mcp.webui # Or using the CLI webui ``` ### Access Points - **Main Interface**: http://localhost:5000 - **Configuration**: http://localhost:5000/config - **API Documentation**: Available through browser console ### Configuration Fields #### Stata Configuration - **Stata CLI Path**: Full path to Stata executable - **Validation**: File existence, executable permissions, format checking - **Examples**: - macOS: `/Applications/Stata/StataMP.app/Contents/MacOS/stata-mp` - Linux: `/usr/local/stata17/stata-mp` - Windows: `C:\Program Files\Stata17\StataMP-64.exe` #### Output Configuration - **Output Base Path**: Directory for storing all Stata outputs - **Validation**: Directory existence/writability, automatic creation - **Default**: `~/Documents/stata-mcp-folder` #### LLM Configuration - **LLM Type**: Choose between Ollama (local) or OpenAI (cloud) - **Options**: `"ollama"`, `"openai"` ##### Ollama Settings (when LLM_TYPE="ollama") - **Model Name**: Name of the Ollama model to use - **Default**: `"qwen2.5-coder:7b"` - **Examples**: `"llama2"`, `"codellama"`, `"mistral"` - **Base URL**: Ollama server URL - **Default**: `"http://localhost:11434"` - **Validation**: Valid HTTP/HTTPS URL format ##### OpenAI Settings (when LLM_TYPE="openai") - **Model Name**: OpenAI model to use - **Default**: `"gpt-3.5-turbo"` - **Examples**: `"gpt-4"`, `"gpt-4-turbo"` - **Base URL**: OpenAI API endpoint - **Default**: `"https://api.openai.com/v1"` - **Validation**: Valid HTTP/HTTPS URL format - **API Key**: Your OpenAI API key - **Validation**: Must start with "sk-", minimum 20 characters - **Security**: Hidden input field, not logged ### Operations #### Save Configuration 1. Navigate to /config 2. Enter valid paths for both fields 3. Click "Save Configuration" 4. Configuration is validated and saved with automatic backup #### Import Configuration 1. Click "Import Configuration" in dropdown menu 2. Select a valid JSON configuration file 3. Configuration is validated and applied #### Export Configuration 1. Click "Export Configuration" in dropdown menu 2. Configuration is downloaded as JSON file #### Reset to Defaults 1. Click "Reset to Defaults" in dropdown menu 2. Confirm the action 3. Current configuration is backed up and reset to defaults ## Validation Features ### Stata CLI Path Validation - ✅ Path existence check - ✅ File type verification - ✅ Executable permissions (Unix systems) - ✅ Platform-specific format validation - ✅ Suggestions for common locations ### Output Path Validation - ✅ Directory existence/writability - ✅ Automatic directory creation - ✅ Permission checking - ✅ Path format validation - ✅ Default suggestions ### LLM Configuration Validation - ✅ LLM type validation (ollama/openai only) - ✅ Ollama model name validation - ✅ Ollama URL format validation - ✅ OpenAI model name validation - ✅ OpenAI URL format validation - ✅ OpenAI API key format validation (sk- prefix) - ✅ Dynamic validation based on selected LLM type ## Security Features - **Path Traversal Protection**: All paths are validated and sanitized - **File Upload Security**: JSON format validation for imports - **Input Sanitization**: All user inputs are cleaned - **Backup Creation**: Automatic backups prevent data loss ## Browser Compatibility - ✅ Chrome 80+ - ✅ Firefox 75+ - ✅ Safari 13+ - ✅ Edge 80+ - ✅ Mobile browsers (responsive design) ## Testing Comprehensive test suite covering: - 18 unit tests for validation and routes - Edge case handling for all configuration scenarios - Cross-platform path validation - API endpoint testing - UI component testing Run tests: ```bash python test_webui.py ``` ## Error Handling ### User-Friendly Errors - Clear, actionable error messages - Suggestions for fixing common issues - Visual indicators for validation states - Detailed help text for each field ### Technical Errors - Graceful degradation for API failures - Proper HTTP status codes - Detailed server-side logging - Client-side error handling with retry options ## Future Extensions The current architecture is designed to support future enhancements: - Modular validation system for additional fields - Extensible API structure for new endpoints - Responsive design ready for additional features - Clean separation of concerns for maintainability ## Quick Start 1. **Install Dependencies**: Already included in pyproject.toml 2. **Start Server**: `webui` command 3. **Open Browser**: Navigate to http://localhost:5000 4. **Configure**: Set your Stata path and output directory 5. **Save**: Configuration is validated and saved ## Troubleshooting ### Common Issues - **"Path does not exist"**: Check the exact file path - **"Directory not writable"**: Check permissions or try a different location - **"Invalid JSON"**: Ensure you're importing a valid JSON file from export ### Debug Mode Run with debug mode for detailed error information: ```bash python -m stata_mcp.webui ``` The web UI is now complete and ready for production use with comprehensive configuration management capabilities for Stata-MCP v1.6.0.
