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

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

```

## Why use_prismatic_barrier is rated Critical

An AI agent that decides to call use_prismatic_barrier doesn't hesitate, doesn't double-check, and doesn't stop at one. Whatever it removes from Torch-to-Crown is gone. There is no undo for destructive operations.

Risk signals: Bulk/mass operation — affects multiple targets

## Use case

AI agents call use_prismatic_barrier to permanently remove resources in Torch-to-Crown, 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 Torch-to-Crown:

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