## Why cancel_withdrawal is rated Critical

While not technically deleting data, canceling a withdrawal is a destructive action that irreversibly undoes a financial operation. The user's intent to move funds is permanently negated without possibility of restoration through this tool alone. Combined with the Bybit trading context (financial exchange), this carries high blast radius if triggered erroneously on a large pending withdrawal.

From the tool's own definition: "'Cancel a pending withdrawal' - this action irreversibly cancels a financial transaction that was in progress, preventing funds from being transferred out of the account."

## Use case

AI agents call cancel_withdrawal to permanently remove resources in Bybit, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)

Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Bybit:

```json
{
  "version": "1",
  "default": "deny",
  "hide": [

  ]
}
```
