## Why forex_historical is rated Low

This tool retrieves historical foreign exchange rate data from an external API (Open Exchange Rates). It is a read-only query operation that returns information without creating, modifying, deleting, or executing any code. The data retrieved is historical and immutable, posing minimal risk if misused by an AI agent.

From the tool's own definition: "Tool name 'forex_historical' and description 'Get historical forex rates' indicate data retrieval with no modification or side effects."

Risk signals: Handles credentials or secrets (api_key)

## Use case

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