AI agents call get_fx_data to retrieve information from Borsa MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool exclusively queries and retrieves financial market data without side effects. It does not create, modify, delete, or execute transactions. Exposure of FX/commodity price data poses minimal direct risk as an AI agent cannot misuse read-only market data to cause harm—the data itself is typically public and non-sensitive. Severity is low due to absence of state-changing operations.
From the tool's definition Tool retrieves FX rates, precious metals, and commodities data in OHLC format with no modification capability.
