WHAT IT DOES

What subscribePosition does on Bybit MCP Server

AI agents call subscribePosition 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 subscribePosition is rated Low

This tool retrieves real-time data about user positions—a read operation with no side effects. While position data is sensitive financial information, the tool itself does not execute trades, transfer funds, modify positions, or delete data. The risk is limited to information disclosure rather than action.

From the tool's definition Tool name 'subscribePosition' and description 'Subscribe to real-time position updates' indicate data retrieval via WebSocket stream subscription.
