## Why stockScreener is rated Low

The stockScreener tool retrieves and filters market data to support research and analysis. It returns information about stocks matching specified criteria but does not create, modify, delete, or execute any financial transactions. This is a read-only query operation with no side effects on financial positions or data state.

From the tool's own definition: "Tool performs filtering and discovery of stocks based on criteria (market cap, price, volume, beta, sector, country)."

Risk signals: High parameter count (19 properties)
