## Why get_liquidation_history is rated Low

This tool performs a read-only query of historical financial data. Even though liquidation events have financial significance, the tool itself only retrieves already-occurred events; it does not create, modify, or execute any transactions or operations.

From the tool's own definition: "Tool name is 'get_liquidation_history' and description states 'Get historical liquidation events'. This retrieves historical data with no side effects—it queries past liquidation information from the Derive API without creating, modifying, or deleting data."

## Use case

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