Anthropic has released sandbox-runtime (srt) as an open-source project. It is the same OS-level sandbox that powers Claude Code, providing fine-grained restrictions on file system and network access for AI agents, MCP servers, and CLI tools. Rather than relying on Docker or other container runtimes, srt leverages native OS security primitives — Apple's Seatbelt on macOS and bubblewrap on Linux — to isolate agent processes.
The approach matters because AI agents increasingly execute code, read files, and make network calls on behalf of users. A lightweight, container-free sandbox reduces overhead while still preventing accidental or malicious data exfiltration. Developers integrating agents into local workflows can adopt srt without managing container images or orchestration layers.
By open-sourcing the runtime, Anthropic gives the broader agent ecosystem a reference implementation for OS-level isolation. Teams building their own agent tools can study or fork srt rather than building sandboxing from scratch, potentially raising the security baseline for agentic AI applications across the industry.
