Get current stock quote information
AI agents call get-stock-quote to retrieve information from Stocks MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

The misuse risk is informational only (e.g., using stale data for decisions), not a direct financial transaction or irreversible action. Classified as Read with low severity.
