Amazon Bedrock adds per-user access control for knowledge base MCP tools

The non-obvious part is that authorization is enforced outside the agent, by gateway policy plus a resource-based policy on the knowledge base, so a compromised or careless agent cannot leak documents. Teams deploying multi-tenant RAG agents on AWS should replicate this three-layer pattern rather than trusting agent-level filtering. Compared with self-built MCP gateways, it reuses AgentCore's identity injection, cutting custom auth plumbing.
