set_mmp · Bybit MCP: Risk & Policy

WHAT IT DOES

What set_mmp does on Bybit

AI agents use set_mmp 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 set_mmp needs a policy

Setting MMP parameters is a configuration change that adjusts trading protection thresholds and behaviors. This is reversible (parameters can be adjusted again) and does not irreversibly delete data or execute arbitrary code. While it affects trading operations, it is not immediately financial (no money moves) and not destructive.

From the tool's definition Tool name 'set_mmp' and description 'Set Market Maker Protection (MMP) parameters' indicate configuration modification of trading protection settings. The verb 'set' in both name and description confirms this creates or modifies data reversibly.

set_mmp Rate-limited

set_mmp 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.
