Everybody's talking about AI agents — but how do you actually build one?

What you'll build: - A basic agent in 3 lines of code - Custom tools using the @tool decorator - A system prompt to shape agent behavior - An MCP server connection for real-world tool use Resources: Strands Agents: https://go.aws/3QnE19c Strands Agents SDK: https://go.aws/4u88KWt Kiro: https://go.aws/4vP0Jaw Amazon Bedrock AgentCore: https://go.aws/4sKxW3V uv (Python package manager): https://go.aws/3OUUSQb Follow AWS Developers!
