Strands Agents

Strands is an open source toolkit for constructing production AI agents in Python and TypeScript. It provides a fully assembled agent harness, harness SDK for custom builds, sandboxed execution environment (Box), virtual shell, evaluation tools, and experimental labs. Box combines OS-level isolation with Dogwood policy language to control agent access and actions. The toolkit includes built-in tools for shell operations, file access, web requests, and MCP server integration, plus production deployment guides for AWS Lambda, Fargate, EKS, and Docker.

Designed for developers building AI agents at scale. Includes session persistence, long-term memory, multi-agent coordination, observability features, and responsible AI guardrails. Currently supports local execution on macOS with Apple silicon, in preview.
