Amazon Quick outlines multi-gate authorization for MCP tool invocations
An Amazon blog post provides a walkthrough to implement defense-in-depth authorization for Model Context Protocol (MCP) tool invocations on Amazon Quick. It describes a Lambda ‘interceptor’ behind an Amazon Bedrock AgentCore Gateway that evaluates OIDC JWT claims through four sequential gates (MFA, geographic restriction, group-to-role mapping, and tool-level permission checks) and shows how to configure Microsoft Entra ID, environment variables, and AWS components to enforce role- and attribute-based controls and parameter-level restrictions.
