# Utils
## Purpose
Comprehensive utility modules providing enhanced FastMCP server functionality with automatic schema generation, result serialization, and execution monitoring.
## Key Components
- **schema_generator.py**: Automatic JSON schema generation from Python type hints with comprehensive security constraints and documentation extraction
- **serialization.py**: Type-safe result serialization and validation with security filtering and performance optimization
- **tool_monitoring.py**: Comprehensive tool execution monitoring with performance tracking, error analysis, and statistical insights
- **errors.py**: Centralized error handling with security-conscious error messages and audit logging integration
## Architecture & Dependencies
**External**: None beyond standard library for maximum reliability and security
**Internal**: Type system for domain types, security contracts for validation, boundaries for audit logging
**Patterns**: Strategy pattern for serialization formats, Observer pattern for metrics collection, Decorator pattern for tool instrumentation
## Critical Considerations
- **Security**: All utilities implement comprehensive security validation with input sanitization and result filtering
- **Performance**: O(1) operations with intelligent caching and minimal overhead for high-frequency usage
- **Integration**: Seamless integration with FastMCP server through enhanced server extensions and monitoring systems
