Why pg_detect_query_anomalies is rated Low

This tool analyzes historical query execution metrics to identify anomalies—a pure read operation that queries existing performance data. It has no side effects, does not execute queries, does not modify data, and does not delete anything. The blast radius of misuse is minimal; an agent could only retrieve diagnostic information about query performance patterns.

From the tool's definition Tool name 'pg_detect_query_anomalies' and description 'Detects queries deviating from their historical execution time norms' indicate a monitoring/analytical operation that retrieves and analyzes query performance data without modifying, executing, or…
