apktool_decompile · Kali MCP: Risk & Policy

WHAT IT DOES

What apktool_decompile does on Kali

AI agents invoke apktool_decompile to trigger actions in Kali. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why apktool_decompile needs a policy

The tool executes the Apktool decompiler against an APK file. This is an Execute category action as it runs an external tool/process. While decompilation itself is a read-like operation (it doesn't modify the original APK), it executes a binary and produces output artifacts on the filesystem.

apktool_decompile Rate-limited

apktool_decompile 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.
