## Facts

- Tool: `app`
- 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": "app",
    "arguments": {}
  }
}
```

## Why app is rated High

This tool manages application lifecycle including launching and stopping apps (Execute-level operations that trigger external processes) and installing apps (potentially installing arbitrary software on a device). The 'list' operation is read-only but the dominant risk is from launch/stop/install actions.

From the tool's own definition: "App lifecycle: launch, stop, install, list — covers launching, stopping, and installing apps on mobile devices"

## Use case

AI agents invoke app 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": {
    "app": {
      "limits": [
        {
          "counter": "app_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```
