## 🗒️ Sample Prompts
### 🔍 Basic Code Understanding
- “List all smali directories for the dvac project.”
- “Show me all the smali files under the package prefix com.vulnerable.component in the dvac project.”
- “Get the smali code for the class com.vulnerable.component.MainActivity.”
- “Compare MainActivity.smali with its previous version and show differences.”
- “Search for usage of startActivity in smali files of dvac project.”
### 🛡️ Vulnerability Detection
- “Analyze declared permissions in the dvac AndroidManifest.xml and flag dangerous ones.”
- “Search for hardcoded URLs or IPs in all .xml and .smali files in the project.”
- “Find all uses of PendingIntent.getActivity in smali files.”
- “Check for exported activities or receivers in dvac’s AndroidManifest.xml.”
- “List all smali files that access android.permission.SEND_SMS or READ_CONTACTS.”
### 🛠️ Reverse Engineering Helpers
- “Decode this APK: dvac.apk and create a project called dvac.”
- “Create a new APKTool project called test-harness.”
- “Clean the dvac project before rebuild.”
- “Extract DEX files from dvac project for external analysis.”
- “Modify MainActivity.smali to insert a log line at the beginning of onCreate().”
### 📦 Static Analysis
- “Get the complete AndroidManifest.xml from dvac project.”
- “Show the contents of apktool.yml for the dvac project.”
- “List all resource files of type layout.”
- “Search for the word password in all resource and smali files.”
- “Check which permissions are used and compare them against typical over-permissioning risks.”
### 🤖 AI Code Modification
- “Modify the onCreate() method in MainActivity.smali to add a toast message.”
- “Replace all http:// links with https:// in strings.xml.”
- “Add the android:exported=false attribute to all activities in the AndroidManifest.xml.”
- “Patch the method validateLogin in LoginManager.smali to always return true.”
- “Add logging statements to every method in MainActivity.smali.”
### 📄 Documentation & Metadata
- “List all decoded APKTool projects in the workspace.”
- “Show me the apktool.yml config to review the version, original APK metadata, and compression settings.”
- “Get all available Android devices connected via ADB. (To be migrated to ADB MCP Server.)”
- “Get metadata about the project dvac from its apktool.yml.”
- “Check which APKTool version is currently installed on the server.”

## 🛠️ Getting Started
### 1. Downlaod from Releases: https://github.com/zinja-coder/apktool-mcp-server/releases
```bash
# 0. Download and install apktool
https://apktool.org/docs/install
# 1. Test whether apktool has been correctly configured in the environment variables
$ apktool -version
# 2. Download the apktool-mcp-server-<version>.zip
https://github.com/zinja-coder/apktool-mcp-server/releases
# 3.
unzip apktool-mcp-server-<version>.zip
├apktool-mcp-server/
├── apktool_mcp_server.py
├── requirements.txt
├── README.md
├── LICENSE
# 4. Navigate to apktool-mcp-server directory
cd apktool-mcp-server
# 5. This project uses uv - https://github.com/astral-sh/uv instead of pip for dependency management.
## a. Install uv (if you dont have it yet)
curl -LsSf https://astral.sh/uv/install.sh | sh
## b. OPTIONAL, if for any reasons, you get dependecy errors in apktool-mcp-server, Set up the environment
uv venv
source .venv/bin/activate # or .venv\Scripts\activate on Windows
## c. OPTIONAL Install dependencies
uv pip install httpx fastmcp
# The setup for apktool-mcp-server is done.
```
## 2. Running on Local LLM Using Ollama and Zin MCP Client - Recommended
<div align="center">
<a href="https://github.com/zinja-coder/zin-mcp-client">
<img alt="zin-mcp-client" height="360px" widht="480px" src="https://github.com/user-attachments/assets/0e8e0ecd-0520-422e-a007-03dc62c4118e">

⚡ Lightweight, Fast, Simple, CLI-Based MCP Client for STDIO MCP Servers, to fill the gap and provide bridge between your local LLMs running Ollama and MCP Servers.
Check Now: https://github.com/zinja-coder/zin-mcp-client
Demo: Coming soon...
## 🤖 3. Claude Desktop Setup
Make sure Claude Desktop is running with MCP enabled.
For instance, I have used following for Kali Linux: https://github.com/aaddrick/claude-desktop-debian
Configure and add MCP server to LLM file:
```bash
nano ~/.config/Claude/claude_desktop_config.json
```
- Windows: `%APPDATA%\Claude\claude_desktop_config.json`
- macOS: `~/Library/Application Support/Claude/claude_desktop_config.json`
And following content in it:
```json
{
"mcpServers": {
"apktool-mcp-server": {
"command": "/<path>/<to>/uv",
"args": [
"--directory",
"</PATH/TO/>apktool-mcp-server/",
"run",
"apktool_mcp_server.py"
]
}
}
}
```
Replace:
- `path/to/uv` with the actual path to your `uv` executable
- `path/to/apktool-mcp-server` with the absolute path to where you cloned this
repository
Then, navigate code and interact via real-time code review prompts using the built-in integration.
## 4. Cherry Studio Setup
If you want to configure the MCP tool in Cherry Studio, you can refer to the following configuration.
- Type: stdio
- command: uv
- argument:
```bash
--directory
path/to/apktool-mcp-server
run
apktool_mcp_server.py
```
- `path/to/apktool-mcp-server` with the absolute path to where you cloned this
repository
