WHAT IT DOES

What subscribeTickers does on Bybit MCP Server

AI agents call subscribeTickers 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 subscribeTickers is rated Low

The tool subscribes to ticker/market snapshot data, which is a real-time data feed operation with no side effects. It retrieves market information (prices, volumes, etc.) from Bybit without modifying any state or executing trades.

From the tool's definition 订阅行情快照（Ticker） — 'subscribe' to market snapshot/ticker data; this is a read/stream operation retrieving market data

RECOMMENDED RULE

The rule that runs subscribeTickers safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Bybit MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For subscribeTickers, this is the rule to start with:

subscribeTickers Allowed

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

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "subscribeTickers": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Bybit MCP Server, apply this rule, and every subscribeTickers call is checked against it from then on.
