AI agents call wsBatchCancelOrders to permanently remove resources in Bybit MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Cancelling orders is an irreversible action — once cancelled, those orders cannot be reinstated. Batch cancellation amplifies the blast radius, potentially cancelling many active trading orders simultaneously. This maps to Destructive given the irreversible nature of order cancellation in a financial trading context.
From the tool's definition Batch cancel multiple existing unfilled or partially filled orders in a single WebSocket request
Documented attack patterns abuse exactly the kind of access wsBatchCancelOrders 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 wsBatchCancelOrders:
{
"version": "1",
"default": "deny",
"hide": [
"wsBatchCancelOrders"
]
}wsBatchCancelOrders disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Confirm symbol, side, quantity, and price with the user before calling. Response is an acknowledgment only; use subscribeOrder or REST endpoints to verify actual order status. It is categorised as a Destructive tool in the Bybit MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Bybit MCP Server MCP server in PolicyLayer and add a rule for wsBatchCancelOrders: 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.
wsBatchCancelOrders is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the wsBatchCancelOrders 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 wsBatchCancelOrders. 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.
wsBatchCancelOrders 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.
