Get real-time stock quote for a symbol (e.g., AAPL, TSLA, MSFT)
AI agents call get_quote to retrieve information from Financial Modeling Prep (FMP) 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 real-time stock quotation data—a read-only operation with no side effects. It does not create, modify, delete, or execute any operations. Even if misused by an AI agent, the worst outcome is accessing or displaying stock price information, which causes no financial harm or operational risk. The low severity reflects the read-only nature and lack of actionable consequences.
From the tool's definition Tool name 'get_quote' and description 'Get real-time stock quote for a symbol' indicate retrieval of publicly available market data with no modification or execution of operations.
