Latest update (11-11 15:52): AWS explains push-based sync for Agent Registry MCP server updates

Overview: AWS Machine Learning Blog describes an event-driven pipeline that keeps AWS Agent Registry records current when MCP servers in Amazon Bedrock AgentCore change their tools or schemas. The pipeline uses AWS CloudTrail to capture UpdateAgentRuntime calls, Amazon EventBridge to route them across accounts, and AWS Lambda to fetch the server's tools and update the matching registry record.

The post says the setup works in both single-account and multi-account deployments.
