WHAT IT DOES

What addReduceMargin does on Bybit MCP Server

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

RISK

Why addReduceMargin is rated Medium

This tool modifies the margin allocated to a trading position. While it doesn't directly move money or place trades, adjusting margin on leveraged positions can significantly affect liquidation thresholds and risk exposure. It's a reversible write operation (margin can be added back), but misuse could lead to forced liquidations, making severity high.

From the tool's definition Add or reduce margin for a position in isolated margin mode. Use a positive value to add margin, or a negative value to reduce margin.
