AI agents call mt5_market_depth to retrieve information from MT5 MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves Depth of Market (order book) data for a symbol. This is a pure read/query operation with no side effects. It only returns market depth information and does not place orders or modify any state. Severity is low as misuse only results in data retrieval, not financial or destructive consequences.
