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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "kill_process",
    "arguments": {}
  }
}
```

## Why kill_process is rated Critical

Killing a process is irreversible — once terminated, any unsaved state, in-flight work, or transient data is lost and cannot be recovered. SIGKILL is especially destructive as it bypasses graceful shutdown handlers. Even SIGTERM can cause data loss or service disruption. The blast radius is high because misuse could terminate critical application or infrastructure processes, causing outages.

From the tool's own definition: "Terminate a process by PID... SIGKILL requires confirmed=true. System processes are protected."

## Use case

AI agents call kill_process to permanently remove resources in Terminal Guardian, 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 Terminal Guardian:

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