## Facts

- Tool: `system`
- Server: Claude Mobile (`alexgladkov/claude-in-mobile`) — https://policylayer.com/tools/alexgladkov-claude-in-mobile.md
- Homepage: https://github.com/AlexGladkov/claude-in-mobile
- Risk category: Execute (High risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

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

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

## Why system is rated High

The ability to run arbitrary shell commands on a mobile device is a classic Execute category risk. While clipboard and file operations could be Read or Write in isolation, the inclusion of shell command execution elevates this to Execute. An AI agent with shell access could execute potentially harmful commands, modify system state, install malware, exfiltrate data, or compromise device security.

From the tool's own definition: "Tool enables shell command execution ('shell: run command'), device log access ('logs: device logs'), clipboard operations ('clipboard_*: Android clipboard'), permission management ('permission_*: app permissions'), and file operations ('file_*: Aurora file…"

## Use case

AI agents invoke system to trigger actions in Claude Mobile. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Claude Mobile:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "system": {
      "limits": [
        {
          "counter": "system_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```
