## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

## Why cancel_order is rated Critical

Cancelling a pending order is an irreversible action: once cancelled, the order is gone and cannot be restored. While it does not move money directly, it permanently removes a market commitment. Given this is on a live trading platform (Bybit) with real financial instruments, misuse could disrupt trading strategies or cause financial harm.

From the tool's own definition: "Cancel a single pending order immediately — cancellation of a financial order is irreversible; the order cannot be reinstated once cancelled."

## Use case

AI agents call cancel_order 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.

## Recommended policy (PolicyLayer)
