AWS Strands Agents & AgentCore

Overview

AWS Strands Agents SDK: Open-source Python framework for building AI agents with model-driven orchestration (minimal code, model decides tool usage)

Amazon Bedrock AgentCore: Enterprise platform for deploying, operating, and scaling agents in production

Relationship: Strands SDK runs standalone OR with AgentCore platform services. AgentCore is optional but provides enterprise features (8hr runtime, streaming, memory, identity, observability).

Quick Start Decision Tree

What are you building?

Single-purpose agent:

Event-driven (S3, SQS, scheduled) → Lambda deployment
Interactive with streaming → AgentCore Runtime
API endpoint (stateless) → Lambda

Multi-agent system:

Deterministic workflow → Graph Pattern
Autonomous collaboration → Swarm Pattern
Simple delegation → Agent-as-Tool Pattern

Tool/Integration Server (MCP):

ALWAYS deploy to ECS/Fargate or AgentCore Runtime
NEVER Lambda (stateful, needs persistent connections)

See architecture.md for deployment examples.

Critical Constraints

MCP Server Requirements

Transport: MUST use streamable-http (NOT stdio)
Endpoint: MUST be at 0.0.0.0:8000/mcp
