# Build a multi-account AI agent with AgentCore Gateway and MCP

## Retrieval answer

AWS has published a reference architecture for a multi-account AI agent.

AWS has published a reference architecture for a multi-account AI agent. A central platform account runs an agent through Amazon Bedrock AgentCore Gateway and MCP, while line-of-business AWS accounts retain their own data and expose MCP servers for secure, fine-grained cross-account access. The pattern frames MCP as the interface between a shared agent layer and independently governed data domains.
