- Change service result logging from INFO to DEBUG level
- Replace full result logging with summary for tools/list operations
- Reduce parameter logging to DEBUG level to avoid sensitive data exposure
- Keep essential method logging at INFO level for monitoring
- Significantly reduces log volume during MCP tools discovery
