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

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

  "params": {

## Why delete_master_api_key is rated Critical

Deleting a master API key is a permanent, irreversible action that cannot be undone. This matches the Destructive category definition ('irreversibly deletes... actions that cannot be undone'). The severity is critical because loss of the master API key blocks all API access and could lock an account holder out of their own trading operations.

From the tool's own definition: "Tool name explicitly states 'delete' and description says 'Delete the current master API key' — this is an irreversible destruction of authentication credentials."

## Use case

AI agents call delete_master_api_key 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": [
    "delete_master_api_key"
  ]
}
```
