Why searchExchangeVariants is rated Low
This tool retrieves publicly available exchange listing information for a given stock symbol. It performs a read-only query against the FMP Exchange Variants API and returns data without modifying, executing, or deleting anything. The blast radius of misuse is minimal—an agent could only retrieve incorrect or unnecessary exchange data, with no financial transactions, code execution, or data destruction possible.
From the tool's definition Tool description states it 'Search across multiple public exchanges to find where a given stock symbol is listed' — a purely informational query operation with no side effects. The verb 'search' and 'find' indicate data retrieval only.
