Get financial indicators (PE, PB, etc.) for a stock.
AI agents call get_stock_indicators to retrieve information from Stock Data MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries financial indicator data without modifying, executing code, deleting data, or moving money. It has no side effects beyond returning market information. The severity is low because misuse would only surface inaccurate financial data to a user, not cause irreversible harm or unauthorized transactions.
From the tool's definition Tool name 'get_stock_indicators' and description 'Get financial indicators (PE, PB, etc.) for a stock' indicate data retrieval only. PE (price-to-earnings) and PB (price-to-book) are read-only financial metrics.
