from strands import Agent
from strands_tools import calculator

agent = Agent(tools=[calculator])
agent("What is the square root of 1764?")
import { Agent } from "@strands-agents/sdk";

const agent = new Agent();
await agent.invoke("What is the square root of 1764?");
pip install strands-agents strands-agents-tools   # Python
npm install @strands-agents/sdk                    # TypeScript

Why Strands?

  • Simple — A minimal agent loop that just works. No boilerplate, no complex abstractions.
  • Model agnostic — Amazon Bedrock, Anthropic, OpenAI, Gemini, Ollama, LiteLLM, llama.cpp, and more. Swap providers in one line.
  • Multi-agent built in — Coordinate agents with Graph, Swarm, and Workflow patterns — plus A2A protocol for cross-framework interop.
  • Native MCP — First-class Model Context Protocol support gives your agents access to thousands of tools.
  • Production readyDeploy to AWS Lambda, Fargate, EKS, Bedrock AgentCore, Docker, Kubernetes, or Terraform with built-in OpenTelemetry observability.
  • Conversational & beyond — Streaming, non-streaming, autonomous agents, structured output, and real-time bidirectional audio conversations.

Community

Strands is built in the open and growing fast. The community contributes model providers (Cohere, xAI, Fireworks AI, NVIDIA NIM, vLLM, MLX, SGLang), session managers (Valkey/Redis, AgentCore Memory), tools (Telegram, HubSpot, Deepgram), and integrations (AG-UI).
