## Why set_collateral_coin is rated Medium

This tool modifies account-level settings (collateral coin configuration) which affects trading position management and collateral handling. While reversible (can be toggled on/off), it's a Write operation rather than Read. Severity is high because misuse could alter account risk parameters or collateral structure, potentially exposing positions to liquidation risk or locking funds in unintended collateral assets.

From the tool's own definition: "Tool name 'set_collateral_coin' and description 'Set collateral coin on or off' indicate modification of account collateral settings. This is a reversible write operation that changes trading account configuration."

## Use case

AI agents use set_collateral_coin to create or update resources in Bybit, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Bybit environment.
