安装

cd so-analyzer-mcp
pip install -r requirements.txt

MCP配置

{
  "mcpServers": {
    "so-analyzer": {
      "command": "python",
      "args": ["K:/path/to/so-analyzer-mcp/run_server.py"]
    }
  }
}

使用示例

# 1. 列出SO库
so_list_libs(apk_path="app.apk")

# 2. 检测Flutter
flutter_detect(apk_path="app.apk")

# 3. 提取SO文件
so_extract(apk_path="app.apk", lib_name="libflutter.so", arch="arm64-v8a")

# 4. 搜索SSL相关函数
so_search_symbol(so_path="libflutter.so", pattern="ssl")

# 5. 提取字符串
so_strings(so_path="libflutter.so", search="certificate")
