Addressing the God Key Challenge in Agentic AI for MCP Servers — Effective Solutions Explained

This report explains the security shortcomings of many agentic AI deployments that use shared, long-lived credentials—resulting in lost user attribution and over-broad permissions—and recommends evolving Zero Trust Network Access to be MCP- and AI-aware. It advocates delegated identity via token exchange, protocol-level MCP inspection, dual identity headers, and an AI>Secure enforcement layer that validates agent and user tokens, parses tool calls, evaluates fine-grained policies, and mints short-lived scoped credentials so downstream MCP services receive least-privilege access.
