Why get_resource_file needs a policy

This tool retrieves resource file content from a decompiled Android/Java application without side effects. It is a query operation consistent with other Read-category tools on this server (get_class_source, get_android_manifest, get_method_code).

From the tool's definition Tool name 'get_resource_file' and description 'Returns the content of a specific resource file' indicate read-only data retrieval with no modification, deletion, or execution.

POLICY

How to control get_resource_file

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_resource_file:

policy.json

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

get_resource_file 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 Jadx 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.
