Cloud container reference
Pre-installed packages, databases, and utilities available in cloud containers.
Cloud containers in Claude Managed Agents come pre-installed with a comprehensive set of programming languages, databases, and utilities. The agent can use these immediately without any installation steps.
These specifications apply to cloud environments. Self-hosted sandboxes run on your infrastructure with whatever your worker provides.
All Managed Agents API requests require the managed-agents-2026-04-01 beta header. The SDK sets the beta header automatically.
