Amazon published a guide for building a multi-account AI agent architecture using Amazon Bedrock AgentCore Gateway and Model Context Protocol (MCP). The design keeps each team's data in its own AWS account while providing a unified query endpoint through a central platform account. The post walks through setting up cross-account MCP integration, authentication with AgentCore Identity and Okta, and fine-grained authorization with Policy in Amazon Bedrock AgentCore.

## Evidence

Verbatim from https://aws.amazon.com/blogs/machine-learning/build-a-multi-account-ai-agent-with-agentcore-gateway-and-mcp/:

> Enterprises increasingly want AI agents that can reason over data spread across many AWS accounts without copying or centralizing it. Each team keeps its data in its own account for good reasons: clear ownership, scope isolation, and independent deployment lifecycles.
