xcode_revoke_privacy_permission

THE RISK

High Risk

This tool modifies system-level privacy permissions for an app (e.g., camera, location, contacts access). While it is a reversible change (permissions can be re-granted), it triggers an external OS-level operation that affects app behavior and security posture.

HOW TO CONTROL XCODE_REVOKE_PRIVACY_PERMISSION

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "xcode_revoke_privacy_permission": {
      "limits": [
        {
          "counter": "xcode_revoke_privacy_permission_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

xcode_revoke_privacy_permission stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

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