~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "jadx-ai-mcp": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/zinja-coder/jadx-ai-mcp"
      ]
    }
  }
}

Abra Claude Desktop → Settings → Developer → Edit Config. Reinicie após salvar.

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "jadx-ai-mcp": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/zinja-coder/jadx-ai-mcp"
      ]
    }
  }
}

Cursor usa o mesmo esquema mcpServers que o Claude Desktop. Config de projeto vence a global.

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "jadx-ai-mcp": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/zinja-coder/jadx-ai-mcp"
      ]
    }
  }
}

Clique no ícone MCP Servers na barra lateral do Cline, depois "Edit Configuration".

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "jadx-ai-mcp": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/zinja-coder/jadx-ai-mcp"
      ]
    }
  }
}

Mesmo formato do Claude Desktop. Reinicie o Windsurf para aplicar.

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "jadx-ai-mcp",
      "command": "TODO",
      "args": [
        "See README: https://github.com/zinja-coder/jadx-ai-mcp"
      ]
    }
  ]
}

O Continue usa um array de objetos de servidor em vez de um map.

~/.config/zed/settings.json

{
  "context_servers": {
    "jadx-ai-mcp": {
      "command": {
        "path": "TODO",
        "args": [
          "See README: https://github.com/zinja-coder/jadx-ai-mcp"
        ]
      }
    }
  }
}

Adicione em context_servers. Zed recarrega automaticamente ao salvar.

claude mcp add jadx-ai-mcp -- TODO 'See README: https://github.com/zinja-coder/jadx-ai-mcp'

Uma linha só. Verifique com claude mcp list. Remova com claude mcp remove.

Casos de uso

Usos do mundo real: jadx-ai-mcp

How to analyze an Android APK with AI assistance using JADX

👤 Mobile security researchers analyzing APKs they have authorization to test ⏱ ~45 min intermediate

Quando usar: You have an APK to analyze and want AI to help understand its behavior.

Pré-requisitos

JADX with jadx-ai-mcp plugin — jadx plugins --install 'github:zinja-coder:jadx-ai-mcp'
JADX MCP Server running — Set up the Python MCP server with uv

Fluxo

Check the manifest

Get the AndroidManifest.xml. What permissions does this app request and what components (activities, services, receivers) does it declare?✓ Copiado

→ Parsed manifest with permission analysis
Find interesting classes

Search for classes related to network communication or encryption. List them with their methods.✓ Copiado

→ Filtered class list with method signatures
Analyze and rename

Get the source code of the main network class. Rename obfuscated methods to descriptive names based on their behavior.✓ Copiado

→ Decompiled code with meaningful names applied

Resultado: An annotated view of the APK with key functionality understood and obfuscation partially reversed.

Armadilhas

Heavily obfuscated apps resist decompilation — Use get_smali_of_class for bytecode-level analysis when decompilation fails

Combine com: filesystem

Debug an Android app with AI-assisted breakpoint analysis

👤 Android developers and security researchers debugging app behavior ⏱ ~30 min advanced

Quando usar: You need to understand runtime behavior that isn't clear from static analysis.

Pré-requisitos

JADX configured for debugging — Connect JADX debugger to a running Android app or emulator

Fluxo

Set breakpoints and inspect

I'm debugging the login flow. Show me the current stack frames and local variables at the authentication method.✓ Copiado

→ Stack trace with variable values at the breakpoint

Resultado: Runtime understanding of app behavior at critical code points.

Armadilhas

App detects debugger and exits — Look for anti-debugging checks in the code and bypass them before attaching

Combinações

Combine com outros MCPs para 10× de alavancagem

jadx-ai-mcp + filesystem

Export decompiled and annotated code for documentation

Export the decompiled source of the authentication module and save it to ~/analysis/auth-module.java.✓ Copiado

Ferramentas

O que este MCP expõe

Ferramenta	Entradas	Quando chamar
fetch_current_class	none	Get the currently selected class source code
search_classes_by_keyword	keyword: str	Find classes matching a keyword
get_android_manifest	none	Retrieve the AndroidManifest.xml
rename_class	old_name: str, new_name: str	Rename an obfuscated class
xrefs_to_method	class_name: str, method_name: str	Find all references to a method
get_smali_of_class	class_name: str	Get Dalvik bytecode (smali) for a class
debug_get_stack_frames	none	Get current debugger stack frames

Custo e limites

O que custa rodar

Cota de API: N/A — fully local
Tokens por chamada: 200–2000 tokens per tool call
Monetário: Free — both JADX and the plugin are open source
Dica: Use search_classes_by_keyword to narrow targets before fetching full class sources.

Segurança

Permissões, segredos, alcance

Armazenamento de credenciais: N/A

Saída de dados: All analysis is local. No network calls from the MCP server.

⚠ This tool is designed for authorized security research, CTF competitions, and defensive analysis only. Do not use it against systems you don't own or have written authorization to test.
Only analyze APKs you have legal right to reverse engineer.

Solução de problemas

Erros comuns e correções

Plugin not loading in JADX

Ensure JADX version is compatible. Try reinstalling with: jadx plugins --install 'github:zinja-coder:jadx-ai-mcp'

Verificar: jadx plugins --list

MCP server connection failed

Ensure the JADX MCP Server is running and the port matches your client config.

Verificar: Check the server terminal for startup messages

Class not found in search

Obfuscated names may not match your search. Try broader patterns or search by method signatures.

Verificar: get_all_classes to see available class names

Alternativas

jadx-ai-mcp vs. outros

Alternativa	Quando usar	Troca
jadx-mcp-server	You only need the MCP server component without the JADX plugin	Server-only — still needs the jadx-ai-mcp plugin in JADX
GhidrAssistMCP	You want to analyze native binaries rather than Android Dalvik bytecode	Native binary focus vs Android-specific tools
