## Why get_all_instruments is rated Low

This tool performs a simple data retrieval operation with no side effects. It queries available financial instruments and returns information, which is characteristic of a Read operation. The severity is low because retrieving publicly available market data poses minimal risk even if misused by an AI agent—there is no capability to modify data, execute commands, delete information, or move funds.

From the tool's own definition: "Tool name 'get_all_instruments' and description 'Get all available instruments' indicate a query operation that retrieves data about available options, perpetuals, or ERC20 tokens without modification."

## Use case

AI agents call get_all_instruments 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.
