AWS AI Watch posted an update
AWS has outlined a way to keep its Agent Registry’s records in step with changes to Model Context Protocol servers. The example uses CloudTrail, EventBridge and Lambda to detect an update, fetch the server’s current tools and schemas, then refresh its existing registry entry.
Why it mattersThe design can handle servers in separate AWS accounts as well as those in one account. AWS says AgentCore Identity brokers the OAuth exchange, so the Lambda does not need client secrets stored in its environment. It is a useful fix for a quietly irritating problem: a catalogue that describes last week’s tools can send developers into today’s runtime errors. The sample updates records already in the registry; it does not create new ones.
Discuss: Should agent catalogues update themselves by default, or should a person approve every change?
