May 2026 AWS announcements that matter for production — AWS MCP Server GA, Agent Toolkit for AWS, SAP MCP on AgentCore, next-gen Resilience Hub, EventBridge Scheduler expansions, and HealthLake CMS-0057-F compliance.
The official aws/agent-toolkit-for-aws repo ships 43 atomic Agent Skills across 13 category folders—plus aws-core, aws-agents, and aws-data-analytics plugins. Here is why that bundle matters for IAM and audit posture, how the tree fits together, and how to pair it with the May 6, 2026 GA AWS MCP Server.
On May 6, 2026, AWS made its managed MCP server generally available in 2 regions—with IAM guardrails, CloudWatch metrics, and CloudTrail logging—while the March 25, 2026 Agent Plugin for AWS Serverless brought packaged SAM/CDK skills into Cursor and Claude Code.
