## Why forex_rate is rated Low

This tool only fetches/retrieves current forex exchange rate information. It has no capability to modify data, execute code, delete anything, or move money. The query is informational only, suitable for read operations. Severity is low because even if misused by an AI agent, retrieving exchange rates poses minimal security risk.

From the tool's own definition: "Tool retrieves exchange rate data from Alpha Vantage API with 'Get a forex exchange rate' - a read-only query operation with no side effects on data."

Risk signals: Handles credentials or secrets (api_key)

## Use case

AI agents call forex_rate 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.
