AWS AI Updates: October 30, 2026

1. AWS Step Functions Workflows Can Now Be Called as Tools by AI Agents

AWS made existing Step Functions Standard and Express workflows available as AI agent tools through Amazon Bedrock AgentCore Gateway, which exposes tools to agents over the Model Context Protocol (MCP). The agent decides when to start a workflow and what input to pass, and Step Functions then executes the defined steps in a fixed order, keeping multi-step business processes deterministic. Agents can also query workflow executions, for example to report which runs failed overnight and at which step. AWS’s example is a support agent that starts a refund workflow while Step Functions handles the eligibility check, manager approval, and credit. The feature is available in all Regions where AgentCore Gateway runs, at standard Step Functions and AgentCore Gateway rates. Source
