Stop following a lead trader. This will stop copying their trades but won
AI agents use BinanceCopyTradingUnfollow to create or update resources in BNB Chain MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your BNB Chain MCP environment.
This tool modifies user trading preferences by removing an active copy-trading subscription. While it doesn't execute trades directly or delete data irreversibly, it writes/updates the state of a financial relationship (unfollowing changes the active copy-trading configuration). The severity is medium rather than high because the action is reversible—the user can re-follow the trader.
From the tool's definition Tool name 'BinanceCopyTradingUnfollow' and description 'Stop following a lead trader. This will stop copying their trades' indicates modification of a trading relationship state.
