OXII Smart Home MCP Server

# OXII MCP Server Tool Logging Implementation Summary ## 🎯 Implementation Overview Successfully implemented comprehensive tool call logging and monitoring system for the OXII Smart Home MCP Server with the following key features: ### ✅ Completed Features #### 1. **Real-time Tool Call Logging** - **Tool Call Tracking**: Every tool call is logged with arguments, results, and execution time - **Success/Error Logging**: Separate logging for successful calls vs. errors - **Statistics Collection**: Automatic collection of tool usage statistics - **Log Format**: ``` 🔧🚀 TOOL_CALLED - tool_name with args: {...} 🔧✅ TOOL_CALL_SUCCESS - Tool: tool_name | Args: {...} | Result: {...} 🔧❌ TOOL_CALL_ERROR - Tool: tool_name | Args: {...} | Error: ... ``` #### 2. **Tool Wrapper System** - **create_logged_tool()**: Wrapper function that adds logging to any tool - **Async/Sync Support**: Handles both synchronous and asynchronous tools - **Attribute Preservation**: Maintains original tool names, docstrings, and annotations - **Error Handling**: Proper error logging and re-raising #### 3. **Web Monitoring Endpoints** - **Health Check**: `GET /health` - Server health status - **Statistics**: `GET /stats` - Tool usage statistics and call counts - **Logs**: `GET /logs` - Recent tool call logs (last 50 entries) - **Reset Stats**: `POST /stats/reset` - Reset all statistics - **Documentation**: `GET /docx` - Beautiful HTML documentation interface - **JSON API**: `GET /docs.json` - Tool definitions in JSON format #### 4. **Statistics Tracking** - **Total Calls**: Overall tool call counter - **Per-Tool Metrics**: Individual tool call counts, success/error rates - **Timestamps**: Start time and last called timestamps - **Real-time Updates**: Statistics update with each tool call #### 5. **Documentation & Web Interface** - **Interactive Web UI**: Beautiful dark-themed documentation interface - **Tool Catalog**: Complete list of available tools with descriptions - **Monitoring Dashboard**: Real-time access to logs and statistics - **Quick Links**: Direct access to all monitoring endpoints ### 🛠 Technical Implementation #### Core Files Modified/Created: 1. **main.py** - Completely restructured with logging system - Tool call statistics tracking - Logging wrapper functions - Web endpoint definitions - HTML documentation templates 2. **test_logging.py** - Comprehensive test suite - Tests all web endpoints - Validates logging functionality - Health check validation 3. **demo_logging.sh** - Demo script - Shows current server status - Displays tool statistics - Lists available tools - Provides usage examples 4. **LOGGING-README.md** - Complete documentation - Feature overview - Usage instructions - API documentation - Example outputs ### 🔧 Key Functions Implemented ```python def log_tool_call(tool_name, args=None, result=None, error=None): """Log tool call with statistics tracking""" def create_logged_tool(original_func): """Create wrapper that logs tool calls""" # Web endpoints for monitoring @app.route("/health") - Health check @app.route("/stats") - Usage statistics @app.route("/logs") - Recent logs @app.route("/stats/reset") - Reset statistics @app.route("/docx") - Documentation interface ``` ### 📊 Monitoring Capabilities #### Statistics Tracked: - Total tool calls across all tools - Per-tool call counts - Success vs. error rates per tool - Last called timestamps - Server start time #### Log Information: - Tool name and arguments for each call - Execution results (truncated to 200 chars) - Error messages for failed calls - Timestamp for each log entry - Structured JSON responses ### 🌐 Web Interface Features #### Documentation Page (`/docx`): - Modern dark-themed UI - Tool catalog with descriptions and parameters - Monitoring section with log format examples - Quick links to all endpoints - README integration #### API Endpoints: - JSON responses for all monitoring data - RESTful design with proper HTTP methods - Error handling with meaningful messages - Real-time data updates ### 🧪 Testing & Validation #### Test Coverage: - ✅ Health endpoint functionality - ✅ Statistics endpoint with data validation - ✅ Logs endpoint with file handling - ✅ Reset functionality - ✅ Documentation endpoints - ✅ Tool registration with logging wrappers #### Demo Functionality: - Interactive demonstration script - Real-time statistics display - Tool catalog presentation - Usage instructions and examples ### 🚀 Deployment Ready #### Features for Production: - **Docker Integration**: Health check endpoint for Docker containers - **Log File Management**: Automatic log file creation and rotation support - **Error Handling**: Comprehensive error handling and recovery - **Performance**: Minimal overhead logging implementation - **Scalability**: Statistics stored in memory with reset capability ### 📈 Usage Statistics Example ```json { "total_calls": 15, "tool_calls": { "get_device_list": { "count": 5, "last_called": "2025-10-22T10:30:45.123456", "success_count": 5, "error_count": 0 }, "switch_device_control": { "count": 10, "last_called": "2025-10-22T10:35:12.789012", "success_count": 8, "error_count": 2 } }, "start_time": "2025-10-22T10:00:00.000000", "current_time": "2025-10-22T10:35:30.456789" } ``` ### 🔗 Quick Access URLs When server is running on localhost:9031: - **Documentation**: http://localhost:9031/docx - **Health Check**: http://localhost:9031/health - **Statistics**: http://localhost:9031/stats - **Recent Logs**: http://localhost:9031/logs - **Tool Definitions**: http://localhost:9031/docs.json ### 💡 Benefits Achieved 1. **Complete Tool Visibility**: Track which tools are being called and how often 2. **Performance Monitoring**: Success/error rates for each tool 3. **Debugging Support**: Detailed logs with arguments and results 4. **Operational Monitoring**: Health checks and statistics for production 5. **Developer Experience**: Beautiful web interface for monitoring 6. **API Integration**: JSON endpoints for external monitoring systems ### 🎉 Implementation Success ✅ **All objectives completed successfully:** - Comprehensive tool call logging system - Real-time statistics tracking - Web-based monitoring interface - Complete documentation and testing - Production-ready deployment features The OXII MCP Server now has enterprise-level logging and monitoring capabilities that provide complete visibility into tool usage patterns and system health.
