WHAT IT DOES

What get_all_packages does on Ultimate Android MCP

AI agents call get_all_packages to retrieve information from Ultimate Android MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why get_all_packages needs a policy

This tool queries and retrieves information about installed packages on an Android device. It has no side effects—it neither modifies, executes, nor deletes anything. The optional filters (user_installed_only, system_installed_only) are read-only parameters that only narrow results. Classification as Read is appropriate.

From the tool's definition Tool returns a list of packages with optional filters for user-installed or system-installed packages. The description explicitly states it 'Returns a list' and accepts only filtering parameters, with no modification, deletion, or execution capability.

POLICY

How to control get_all_packages

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_all_packages": {}
  }
}

get_all_packages is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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