AI agents invoke decode_apk to trigger actions in Apktool MCP Server. 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.
This tool executes APKTool as an external process to decode/disassemble an APK file. It runs a system command with file system side effects (creates output directories, extracts files). The 'force' flag can delete an existing destination directory, introducing a partially destructive element.
From the tool's definition Decode an APK file using APKTool... force: Force delete destination directory if it exists
Documented attack patterns abuse exactly the kind of access decode_apk gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Apktool MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for decode_apk:
{
"version": "1",
"default": "deny",
"tools": {
"decode_apk": {
"limits": [
{
"counter": "decode_apk_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}decode_apk 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.

Decode an APK file using APKTool with comprehensive validation and error handling. Args: apk_path: Path to the APK file to decode force: Force delete destination directory if it exists no_res: Do not decode resources no_src: Do not decode sources output_dir: Custom output directory (optional) timeout: Command timeout in seconds Returns: Dictionary with operation results including validation details. It is categorised as a Execute tool in the Apktool MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Apktool MCP Server MCP server in PolicyLayer and add a rule for decode_apk: 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 Apktool MCP Server. Nothing to install.
decode_apk is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the decode_apk 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.
Set action: deny in the PolicyLayer policy for decode_apk. 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.
decode_apk is provided by the Apktool MCP Server MCP server (zinja-coder/apktool-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
