reset_mmp · Bybit MCP: Risk & Policy

WHAT IT DOES

What reset_mmp does on Bybit

AI agents invoke reset_mmp to trigger actions in Bybit. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why reset_mmp needs a policy

Resetting MMP re-enables automated market-making order flow on the exchange. It is not simply a data read or write; it triggers an operational state change on the exchange (unblocking order submission). Misuse could expose the account to unintended mass order placement in volatile markets, making it high severity.

From the tool's definition Reset Market Maker Protection (MMP) — triggers an external operation on the exchange that re-enables market-making activity after a protection halt
