WHAT IT DOES

What subscribeSpreadExecution does on Bybit MCP Server

AI agents call subscribeSpreadExecution 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 subscribeSpreadExecution is rated Low

The tool subscribes to a real-time data stream for spread execution events. Subscribing to a WebSocket feed is a read/monitoring operation with no side effects on orders, positions, or funds. The authentication requirement ('需要鉴权') is for access control, not because it modifies state. Severity is low since misuse only results in receiving market data.

From the tool's definition 订阅 Spread 成交推送 — 'subscribe' and '推送' (push/stream) indicate this is a data subscription for receiving spread execution updates

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs subscribeSpreadExecution safely

subscribeSpreadExecution Allowed

subscribeSpreadExecution is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

  }
}
