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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "PIPESTEAM",
    "arguments": {
      "L": {},
      "M": {},
      "P": {},
      "T": {}
    }
  }
}
```

## Why PIPESTEAM is rated Critical

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

Risk signals: High parameter count (16 properties)

## Use case

AI agents call PIPESTEAM to permanently remove resources in EngScript Engineering 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 EngScript Engineering MCP:

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