Why list_knowledge_bases is rated Low
This tool performs a read-only query to list knowledge bases. It has no side effects, does not execute code, does not modify data, and does not affect financial systems. The blast radius of misuse is minimal—an agent could enumerate knowledge bases but cannot access their contents or cause harm through listing alone. Severity is low as this is informational access to metadata about available resources.
