WHAT IT DOES

What subscribeSpreadOrder does on Bybit MCP Server

AI agents call subscribeSpreadOrder to retrieve information from Bybit MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why subscribeSpreadOrder is rated Low

The tool subscribes to a WebSocket stream for spread order changes, which is a read/monitoring operation. It does not place, modify, or cancel orders. The authentication requirement ('需要鉴权') is because it accesses private account data, not because it performs writes. Severity is low as it only reads streaming data.

From the tool's definition 订阅 Spread 订单变动 — 'subscribe' indicates listening/streaming to order change events
