The Anthropic Sandbox Runtime (srt) is a security tool that creates OS-level restrictions on processes, blocking unwanted filesystem and network access without using containers. It's designed for developers and AI agent creators who need to run untrusted code safely, with built-in support for sandboxed MCP servers and other AI tools. The tool provides a secure-by-default approach where processes start with minimal permissions and you explicitly grant only the access you need.
