Implementation Reference

• apktool_mcp_server.py:457-501 (handler)

  The handler function for the 'get_apktool_yml' MCP tool. It validates the input project directory, checks for the existence of 'apktool.yml', reads its content if present, and returns structured metadata including the file content, path, size, and encoding. Includes comprehensive error handling.
