New OAuth Pattern Solves Identity Loss in AI Gateway Architectures

A technical paper proposes a solution to the identity termination problem in Model Context Protocol (MCP) gateway architectures, where user identities are lost during gateway hops. The proposed Delegated Boundary OAuth (DBO) pattern uses a dual OAuth boundary to ensure that the original user's identity is preserved and used for authorization across all downstream systems. This approach aims to improve audit trails, enforce least-privilege principles, and comply with frameworks like the NIST AI Risk Management Framework. AI

IMPACT Enhances security and auditability for enterprise AI integrations by preserving user identity.
