- Standardized error handling across tool implementations
- Improved return type consistency for tool execution results
- Simplified configuration parsing and type definitions
- Enhanced type safety for various configuration schemas
- Cleaned up and normalized tool response structures
- Updated SSE and event subscription tool implementations
