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.
