MCP centralized auth for enterprise — cutting-edge AI agent protocol directly matching reader focus.
The Model Context Protocol team has promoted its Enterprise-Managed Authorisation (EMA) extension to stable status, enabling organisations to control access to MCP servers centrally via identity providers like Okta, Microsoft, and Anthropic. The extension replaces per-server OAuth consent prompts with a single sign-on flow using the Identity Assertion JWT Authorisation Grant (ID-JAG), separating connection-level auth from per-action runtime decisions. This addresses a major enterprise pain point where repeated authorisation prompts hinder scalable agent deployments, though organisations still need their own controls for runtime actions.
