A comprehensive platform for Java bytecode analysis and Android application reverse engineering, integrating JADX decompiler with AI assistant capabilities through MCP (Model Context Protocol).

• Java 17+ for JIAP Core
• Python 3.10+ for MCP Server
• JADX decompiler with plugin support
• Python dependencies: requests, fastmcp

# Build JIAP Core
cd jiap_core
chmod +x gradlew
./gradlew dist

# Install MCP Server dependencies
cd mcp_server
pip install requests fastmcp

# JADX Command Line 
jadx plugins --install-jar <path-to-jiap.jar>

# JADX GUI 
# JADX -> Plugins -> Install from JAR

• Launch JADX with JIAP plugin enabled
• Verify the server runs on http://127.0.0.1:25419

cd mcp_server
python jiap_mcp_server.py

The MCP server will start on http://0.0.0.0:25420.

Use health_check() to verify the connection between MCP server and JIAP plugin.
