get_stock_price
AI agents call get_stock_price to retrieve information from Crypto Stocks without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves current stock price information without modifying data, executing code, or committing financial transactions. While it relates to financial instruments, it performs only informational lookup (Read category). Severity is low because misuse would only surface incorrect data for analysis, not cause direct harm.
From the tool's definition Tool name 'get_stock_price' indicates data retrieval; server description emphasizes 'tracks real-time data' and 'analyze' rather than modify or transact; sibling tools 'get_historical_prices' and 'get_stock_list' are clearly read-only queries.
