At 2 AM, your on-call engineer has four browser tabs open: CloudWatch Logs, CloudWatch Metrics, a runbook wiki, and Slack. They are synthesizing evidence manually — and every fragmented minute is MTTR climbing. Building an AI agent to close that gap sounds simple until you realize you are actually wiring a runtime, a JWT-gated API layer, an MCP transport, memory persistence, guardrails, observability, and an evaluation harness. This post walks through a production-shaped template that does that wiring once — so you swap four files and ship your own domain. The 7-day demo cost to run the full stack was $2.11 USD . What this article is: A teardown of a fork-and-ship CDK template for multi-agent systems on Bedrock AgentCore. The built-in exemplar is an SRE incident-response system running against seeded demo fixtures in CloudWatch — not real production data. That's intentional: synthetic fixtures prove the pattern works end-to-end so you can swap in your own data sources with confidence.…
