🤖 What is apktool-mcp-server?

apktool-mcp-server is a MCP server for the Apk Tool that integrates directly with Model Context Protocol (MCP) to provide live reverse engineering support with LLMs like Claude.

Think: "Decompile → Context-Aware Code Review → AI Recommendations" — all in real time.

🗒️ 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

🤖 2. 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:

And following content in it:

Then, navigate code and interact via real-time code review prompts using the built-in integration.

To report bugs, issues, feature suggestion, Performance issue, general question, Documentation issue.

• Kindly open an issue with respective template.
• Tested on Claude Desktop Client, support for other AI will be tested soon!
