WHAT IT DOES

What modifyEarnPosition does on Bybit MCP Server

AI agents use modifyEarnPosition 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 modifyEarnPosition is rated Medium

This tool creates or modifies data reversibly by changing the auto-reinvest flag on a position. It does not execute trades, delete positions, or move funds directly—it only adjusts a setting. While it affects earning behavior on the Bybit exchange, the modification can be undone by toggling the setting back. This is characteristic of Write category tools.

From the tool's definition The tool modifies the auto-reinvest setting for a fixed-term OnChain position. The verb 'modify' and 'set/unset' indicate it changes an existing configuration reversibly. It alters position settings without executing trades or deleting data.
