Why delete_all_app_caches needs a policy

This tool performs an irreversible destructive action—removing all cached data for an application. While caches can sometimes be regenerated, the tool itself deletes them without recovery option, placing it in the Destructive category.

From the tool's definition Tool name 'delete_all_app_caches' and description 'Delete all stored caches for an application' explicitly indicate irreversible deletion of data. The word 'Delete' combined with 'all' and the scope of removing cached artifacts cannot be undone.

POLICY

How to control delete_all_app_caches

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

policy.json

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

delete_all_app_caches 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 Codemagic MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
