## Why forecast_barrier_prob is rated Low

Based on the name alone, this tool likely computes statistical forecasts or probabilities related to price barriers, which would be a Read/analytical operation. However, given the server context (MetaTrader5 with trading functionality), there is some risk it could trigger trades or financial operations. The empty description significantly lowers confidence.

From the tool's own definition: "Tool name 'forecast_barrier_prob' suggests forecasting barrier probabilities (e.g., probability of price reaching a barrier level), but the description is empty and uninformative."

## Use case

AI agents call forecast_barrier_prob as a supporting operation in MetaTrader5 MCP Server workflows.

## Recommended policy (PolicyLayer)
