What system_advanced_config does on Nasbridge
AI agents call system_advanced_config to retrieve information from Nasbridge without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why system_advanced_config is rated Low
This tool retrieves system configuration data without modifying, executing, deleting, or moving money. The verb 'Get' clearly indicates a read-only operation. While system configuration data could theoretically be sensitive, the tool itself cannot cause side effects or harm through its own execution. Severity is low because unauthorized access to this information alone does not enable destructive actions.
From the tool's definition Tool description states 'Get advanced system configuration' - a retrieval operation with no modification capability.
