Get stock prices
AI agents call getStocks to retrieve information from MCP Weather Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves stock price information, which is a read-only operation with no capability to execute trades, transfer funds, or modify financial data. While it involves financial data, it does not commit financial obligations or move money, so it does not qualify as 'Financial'. The low severity reflects minimal risk even if misused — an AI agent retrieving stock prices causes no harm.
From the tool's definition Tool name is 'getStocks' with description 'Get stock prices' — this is a retrieval operation that queries financial data without modification or side effects.
