## Why forecast_volatility_estimate is rated Low

This tool performs statistical estimation and forecasting on volatility metrics. It does not execute trades, modify account state, delete data, or commit financial transactions. It is purely a Read operation that computes technical analysis output based on market data inputs. While the MetaTrader5 server has trading capabilities, this specific tool is limited to volatility forecasting analysis.

From the tool's own definition: "Tool description states it 'forecasts volatility' using 'estimators or proxies' — a computational analysis of market data with no side effects, modifications, trades, or execution of actual trading positions."

## Use case

AI agents call forecast_volatility_estimate to retrieve information from MetaTrader5 MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches MetaTrader5 MCP Server:

```json
{
  "version": "1",
