WHAT IT DOES

What set_auto_add_margin does on Bybit

AI agents use set_auto_add_margin 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.

RISK

Why set_auto_add_margin is rated Medium

This tool modifies account/position configuration settings (enabling or disabling auto-margin replenishment) rather than executing trades or moving funds directly. It is reversible—the setting can be toggled back. However, it carries high severity because incorrect auto-margin settings could lead to unintended liquidations or cascading margin calls if an agent misconfigures it during volatile market conditions.

From the tool's definition Tool name 'set_auto_add_margin' and description 'Set auto add margin for a position' indicate modification of account settings that affect position management and margin behavior.
