## AI overview

This tutorial explains how the Enterprise-Managed Authorization extension to MCP uses ID-JAGs--short-lived, signed JWT authorization grants--to let an identity provider authorize a client to access an MCP resource server. The authorization server exchanges the ID-JAG for an access token, replacing repeated user consent screens with centrally managed enterprise authorization. The article notes that the ID-JAG draft remains an active IETF document even though the MCP extension is marked Stable.
