Parameters from the server's own tool schema.
This tool only queries and returns historical stock price data from Alpha Vantage. It is a read-only operation that retrieves data without side effects, modification, or execution. The low severity reflects minimal risk if misused by an AI agent—at worst, it could cause rate-limiting or expose API keys, but cannot cause financial transactions, data loss, or execute arbitrary code.
