LangChain's Deep Agents framework now integrates with Mainbrella sandbox adapter, enabling AI agents to safely execute code and manage files in Linux containers. This integration allows agents to inspect inputs, write scripts, execute them, handle errors, and produce outputs without managing infrastructure manually. The adapter follows existing extension patterns and enables multi-agent workflows with shared workspaces.
