What switchPositionMode does on Bybit MCP Server

RECOMMENDED RULE

The rule that runs switchPositionMode safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Bybit MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For switchPositionMode, this is the rule to start with:

switchPositionMode Rate-limited

switchPositionMode 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.
