Installieren

Wählen Sie Ihren Client

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

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

Öffne Claude Desktop → Settings → Developer → Edit Config. Nach dem Speichern neu starten.

~/.cursor/mcp.json · .cursor/mcp.json

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

Cursor nutzt das gleiche mcpServers-Schema wie Claude Desktop. Projektkonfiguration schlägt die globale.

VS Code → Cline → MCP Servers → Edit

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

Klicken Sie auf das MCP-Servers-Symbol in der Cline-Seitenleiste, dann "Edit Configuration".

~/.codeium/windsurf/mcp_config.json

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

Gleiche Struktur wie Claude Desktop. Windsurf neu starten zum Übernehmen.

~/.continue/config.json

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

Continue nutzt ein Array von Serverobjekten statt einer Map.

~/.config/zed/settings.json

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

In context_servers hinzufügen. Zed lädt beim Speichern neu.

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

Einzeiler. Prüfen mit claude mcp list. Entfernen mit claude mcp remove.

Praxisnahe Nutzung: jadx-mcp-server

How to perform a security audit on an Android APK with JADX MCP

👤 Security auditors reviewing Android applications they are authorized to test ⏱ ~60 min intermediate

Wann einsetzen: You need to review an APK for security vulnerabilities.

Voraussetzungen

JADX with jadx-ai-mcp plugin running with target APK loaded — Install plugin and open the APK in JADX-GUI
jadx-mcp-server running — uv run jadx_mcp_server.py

Ablauf

Check manifest for issues

Get the AndroidManifest.xml. Check for exported components, dangerous permissions, and debug flags.✓ Kopiert

→ Security findings from manifest analysis
Search for insecure patterns

Search for classes that use SharedPreferences, Log.d, or hardcoded URLs. Are there any credentials stored in plain text?✓ Kopiert

→ List of potential security issues with code locations

Ergebnis: A security assessment report with specific code-level findings.

Fallstricke

ProGuard-obfuscated code is hard to follow — Use rename_variable and rename_class to deobfuscate as you analyze

Kombinieren mit: filesystem

Kombinationen

Mit anderen MCPs für 10-fache Wirkung

jadx-mcp-server + filesystem

Save security findings and annotated code to report files

Compile all security findings into a report and save to ~/audits/app-audit.md.✓ Kopiert

Credential-Speicherung: N/A

Datenabfluss: All analysis is local

⚠ 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.

Fehlerbehebung

Häufige Fehler und Lösungen

Server can't connect to JADX

Ensure JADX-GUI is running with the jadx-ai-mcp plugin enabled and an APK is loaded.

Prüfen: Check JADX-GUI for the plugin status indicator

uv not found

Install the uv package manager: curl -LsSf https://astral.sh/uv/install.sh | sh

Prüfen: uv --version

Empty class list

Make sure an APK file is actually loaded in JADX before connecting.

Prüfen: Open an APK in JADX-GUI first

Alternativen

jadx-mcp-server vs. andere

Alternative	Wann stattdessen	Kompromiss
jadx-ai-mcp (plugin)	You want the complete plugin+server setup as a single package	This is the server component — you need both the plugin and server
