clear_app_data

THE RISK

Critical Risk

Clearing all app data is an irreversible operation that permanently deletes user data, cache, and application state. This cannot be recovered or undone without restoring from a backup. This fits the Destructive category rather than Write (which implies reversibility).

From the tool's definition Tool name 'clear_app_data' combined with description 'Clear all data and cache for a specific app' indicates irreversible deletion of application data.

HOW TO CONTROL CLEAR_APP_DATA

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Android Agent, and nothing reaches the server without passing your rules. This is the rule we recommend for clear_app_data:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "clear_app_data"
  ]
}

clear_app_data disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register MCP Android Agent — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
