WHAT IT DOES

What getEarnAprHistory does on Bybit MCP Server

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

RISK

Why getEarnAprHistory is rated Low

This tool retrieves historical APR (Annual Percentage Rate) data for earn products on the Bybit exchange. It performs a passive data query with no side effects—no positions are modified, no transactions occur, and no data is created or deleted. The blast radius of misuse is minimal since an AI agent could only access or enumerate historical financial metrics already public on the exchange.

From the tool's definition Tool name 'getEarnAprHistory' and description 'Query historical daily APR for a product' indicate data retrieval with no modification. The verb 'Query' and 'get' are characteristic of read operations.
