## Key Architecture Principles
1. **Layered Architecture**: Clean separation between:
- MCP Server Layer
- Tool Implementation Layer
- Service Layer
- API Communication Layer
2. **Separation of Concerns**:
- Each tool handles a specific operation type
- Service layer abstracts API communication
- Tools are isolated and independently testable
3. **Robustness**:
- Comprehensive error handling
- Retry mechanisms for API calls
- Input validation and sanitization
- Detailed error messages for debugging
4. **Performance**:
- Caching for frequently accessed data
- Optimized query execution
- Incremental data fetching
- Batched operations when possible
5. **Extensibility**:
- Easy to add new tools
- Entity model can be extended
- Service layer can be enhanced without affecting tools
## Development Approach
The architecture follows modern TypeScript practices:
- **Type Safety**: Strong typing throughout the codebase
- **Async/Await**: Modern asynchronous patterns
- **Error Handling**: Comprehensive error handling with specific error types
- **Modularity**: Clear module boundaries and interfaces
- **Testability**: Components designed for easy testing
