THE RISK

Low Risk

Why subscribeRfqPublicTrades needs a policy

This tool subscribes to a real-time stream of public trade data from Bybit's RFQ market. It retrieves and observes data without creating, modifying, deleting, or executing operations. Public trade data is informational and poses minimal risk if misused—an agent cannot manipulate markets or cause financial harm by merely reading public trade information.

From the tool's definition Tool name 'subscribeRfqPublicTrades' with description '订阅 RFQ 公开成交' (Subscribe to RFQ public trades). The verb 'subscribe' combined with 'public trades' indicates a read-only WebSocket subscription to publicly available market data.

How to control subscribeRfqPublicTrades

PolicyLayer is an MCP gateway — it sits between your AI agents and Bybit MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for subscribeRfqPublicTrades:

policy.json

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

subscribeRfqPublicTrades is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Bybit MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
