What subscribeSpreadTickers does on Bybit MCP Server

AI agents call subscribeSpreadTickers 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.

Why subscribeSpreadTickers is rated Low

This tool subscribes to real-time market data streams (spread tickers) from Bybit. It is a read-only operation that retrieves market information with no side effects on accounts, positions, or financial obligations. While it establishes a WebSocket stream, the action itself is non-destructive data retrieval. Severity is low as misuse would only expose the agent to market data already publicly available.

From the tool's definition Tool name 'subscribeSpreadTickers' and description '订阅 Spread 行情快照' (Subscribe to Spread market data snapshots) indicate real-time market data subscription. The 'subscribe' operation retrieves live ticker data without modifying state.
