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

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

## Why credential-delete is rated Critical

The tool performs permanent deletion of data on the XRP Ledger. While the deletion has authorized access controls (issuer, subject, or anyone for expired credentials), the action itself is irreversible and removes data from the ledger.

From the tool's own definition: "Tool name 'credential-delete' and description states 'Delete a credential from the XRP Ledger' — this is an irreversible deletion operation that cannot be undone."

## Use case

AI agents call credential-delete to permanently remove resources in Xrpl mcp, 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 Xrpl mcp:

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "credential-delete"
  ]
}
```
