Implementing defense-in-depth authorization for MCP tools on Amazon Quick | Amazon Web Services
Each Model Context Protocol (MCP) tool invocation on Amazon Quick is an access event that can require defense-in-depth authorization at the tool and parameter level. This applies in addition to a valid token. Without granular controls, a single misconfigured permission can bypass the access requirements that organizations might need to fulfill for compliance purposes. In this blog post, you implement a multi-gate authorization pattern that evaluates OpenID Connect (OIDC) JSON Web Token (JWT) claims in sequence. The pattern enforces role-based and attribute-based access control on each invocation. You configure which authorization controls to activate based on your compliance requirements, from group-based permissions to parameter-level attribute checks.
