AWS published a step‑by‑step guide showing how an enterprise can connect its LangChain orchestrator to a SaaS compliance agent using the Agent‑to‑Agent (A2A) protocol. The two agents run in separate AWS accounts, authenticate with Amazon Cognito and exchange tasks over HTTPS without sharing secrets. The demo uses Anthropic Claude Sonnet 4.6 for reasoning and Amazon Nova Lite for metadata lookups, and the whole flow is deployed with three Jupyter notebooks.
Why it matters
Enterprises can add third‑party AI agents without custom code, reducing integration effort and keeping each side’s models and tools private.
