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

AWS Machine Learning Blog · Sep 24, 2026 · Engineering Insights

AWS shows how to build multi-account AI agents querying distributed data via AgentCore Gateway and MCP.

“The goal is to let data stay where it already lives, in each line-of-business (LOB) account.”

AWS details a reference architecture for enterprise AI agents that query data across many AWS accounts without centralizing it, using Amazon Bedrock AgentCore Gateway and the Model Context Protocol. It covers cross-account MCP integration, AgentCore Identity with Okta, fine-grained authorization, and governance for production readiness. It matters as a concrete enterprise pattern for scaling agentic systems while preserving data ownership and isolation.
