WHAT IT DOES

What jadx_decompile does on Jshookmcp

AI agents call jadx_decompile to retrieve information from Jshookmcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why jadx_decompile is rated Low

Reads and decompiles APK bytecode into readable source; no data modification.

RECOMMENDED RULE

The rule that runs jadx_decompile safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Jshookmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For jadx_decompile, this is the rule to start with:

jadx_decompile Allowed

jadx_decompile is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Jshookmcp, apply this rule, and every jadx_decompile call is checked against it from then on.
