## Why trade_close is rated Critical

On a MetaTrader5 trading server, 'trade_close' almost certainly closes an open trading position, which is a financial action that commits or settles financial obligations. The empty description lowers confidence slightly, but the context (MT5 trading server, sibling tools focused on market data and trading) and the tool name make this classification highly probable.

From the tool's own definition: "Tool name 'trade_close' on a MetaTrader5 server with trading functionality; description is empty but name strongly implies closing a financial trade/position."

## Use case

AI agents use trade_close to commit financial operations through MetaTrader5 MCP Server, usually the final step of a payment, billing, or trading workflow. A call moves real money.
