## Executive Summary
Learn how to expose an Amazon Bedrock Managed Knowledge Base to AI agents as MCP tools through Amazon Bedrock AgentCore Gateway while keeping per-user access.

## Why It Matters (Strategic Analysis)
Relying on LLM runtime arguments for user permissions exposes enterprise agents to privilege escalation via prompt injection or model hallucination. Architectural enforcement of identity via trusted gateway code rather than model generation resolves critical authorization boundaries in multi-tenant agent deployments.
