Zero-Touch OAuth Goes Standard: How MCP Solves Enterprise Authorization

MCP servers have struggled with enterprise adoption due to manual OAuth flows that create security friction at scale, but Enterprise-Managed Authorization (EMA) now delegates access control to centralized identity providers.

This shift from manual consent to policy-driven access represents a key milestone for deploying AI agents securely in regulated industries.
