get_package_tree

Get all packages in the APK sorted by class count. Shows total_classes, total_packages, and per-package name, class_count, is_likely_library. Use this first to understand the APK structure before searching.

How to control get_package_tree ↓

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

Low Risk

This tool performs read-only operations that retrieve organizational metadata from a decompiled APK. It lists packages, counts classes, and identifies likely libraries—all non-destructive queries with no side effects. The tool is explicitly recommended as a first step for 'understanding APK structure,' indicating its passive reconnaissance nature. No data is modified, deleted, or executed.

From the tool's definition Tool queries and retrieves metadata about APK package structure, class counts, and library classification. Description explicitly states it 'shows total_classes, total_packages, and per-package' information without modification or execution capabilities.

Documented attack patterns abuse exactly the kind of access get_package_tree gives an agent:

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_package_tree": {}
  }
}

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

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

What does the get_package_tree tool do? +

Get all packages in the APK sorted by class count. Shows total_classes, total_packages, and per-package name, class_count, is_likely_library. Use this first to understand the APK structure before searching. It is categorised as a Read tool in the JADX-MCP-SERVER MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on get_package_tree? +

Register the JADX-MCP-SERVER MCP server in PolicyLayer and add a rule for get_package_tree: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches JADX-MCP-SERVER. Nothing to install.

What risk level is get_package_tree? +

get_package_tree is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit get_package_tree? +

Yes. Add a rate_limit block to the get_package_tree rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block get_package_tree completely? +

Set action: deny in the PolicyLayer policy for get_package_tree. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides get_package_tree? +

get_package_tree is provided by the JADX-MCP-SERVER MCP server (zinja-coder/jadx-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every JADX-MCP-SERVER tool call.
