Claude Code Execution Tool (Anthropic)
Anthropic's server-side sandbox lets Claude run Python and Bash inside the API call: a 1 CPU / 5 GiB container with no internet access that you can reuse for 30 days. For agents built on Claude that need data analysis and file generation without running their own sandbox.
