AI agents call subscribeRfqTrades to retrieve information from Bybit MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool subscribes to RFQ (Request for Quote) trade events via WebSocket, which is a read/listen operation. It retrieves real-time trade data without placing orders or moving funds. The authentication requirement ('需要鉴权') is common for private data streams and doesn't imply a write or financial action.
From the tool's definition 订阅 RFQ 成交 — '订阅' means 'subscribe', indicating a real-time data stream subscription rather than an action that modifies state
Documented attack patterns abuse exactly the kind of access subscribeRfqTrades gives an agent:
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 subscribeRfqTrades:
{
"version": "1",
"default": "deny",
"tools": {
"subscribeRfqTrades": {}
}
}subscribeRfqTrades is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

订阅 RFQ 成交（需要鉴权）. It is categorised as a Read tool in the Bybit MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Bybit MCP Server MCP server in PolicyLayer and add a rule for subscribeRfqTrades: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Bybit MCP Server. Nothing to install.
subscribeRfqTrades is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the subscribeRfqTrades rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for subscribeRfqTrades. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
subscribeRfqTrades is provided by the Bybit MCP Server MCP server (bybit-exchange/trading-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Bybit MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
