move_position · Bybit MCP: Risk & Policy

WHAT IT DOES

What move_position does on Bybit

AI agents use move_position 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.

WHY IT NEEDS A POLICY

Why move_position needs a policy

While 'move_position' modifies account state by transferring positions between user IDs, it is reversible (positions can be moved back). This makes it Write rather than Destructive. However, the high blast radius—transferring trading positions between accounts could redirect profits/losses or enable unauthorized account manipulation—warrants high severity.

From the tool's definition Tool name 'move_position' combined with description 'Move positions between UIDs (master API key only)' indicates modification of position ownership/location. The master API key requirement and cross-UID transfer imply significant account-level changes.

Verdict

move_position Rate-limited

move_position stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
