AI agents call get_forecast_today to retrieve information from Curistat 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 volatility forecast data—a pure read operation with no side effects. While the server supports trading agents, this specific tool does not execute trades, move capital, or trigger external operations; it only returns analytical forecasts. The low severity reflects minimal risk even if misused by an AI agent, as it cannot directly cause financial loss or irreversible changes.
