Query invited users (referrals) for the authenticated account. Use master or sub-account
AI agents call queryReferrals 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.
This tool retrieves information about referral users associated with an account. It is a read-only query that returns existing data with no side effects. While it operates on a financial exchange (Bybit), it does not move money or commit financial obligations—it merely lists referral relationships. The blast radius of misuse is low, as unauthorized queries cannot cause irreversible damage or financial loss.
From the tool's definition Tool performs a query operation to retrieve referral data: 'Query invited users (referrals) for the authenticated account.' No modifications, deletions, or financial transactions are performed.
Documented attack patterns abuse exactly the kind of access queryReferrals 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 queryReferrals:
{
"version": "1",
"default": "deny",
"tools": {
"queryReferrals": {}
}
}queryReferrals is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Bybit MCP Server MCP server in PolicyLayer and add a rule for queryReferrals: 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.
queryReferrals 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 queryReferrals 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 queryReferrals. 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.
queryReferrals 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.
