Automating AWS Agent Registry updates with a push-based architecture
AWS outlines an event-driven pipeline that keeps AWS Agent Registry records for MCP servers current without manual updates. AWS CloudTrail captures UpdateAgentRuntime API calls, Amazon EventBridge routes them across accounts, and a Lambda function queries the MCP server's tools via AgentCore Identity OAuth tokens, then diffs and updates the matching registry record. The sample updates existing records only and supports both single- and multi-account setups.
