A new extension to the Model Context Protocol (MCP) introduces enterprise-managed authorization, allowing organizations to centralize access control for MCP servers. Instead of each employee individually authorizing access, the decision is delegated to the organization's identity provider (IdP). Employees log in once via SSO, and the IdP determines which MCP servers they can access based on organizational policies. This approach simplifies security management, reduces the risk of unauthorized access, and aligns with enterprise security best practices. For platform engineers and security architects, this is a crucial step toward safe MCP deployment in corporate environments. The extension leverages existing OAuth flows but adds a layer of policy enforcement at the IdP level, making it easier to audit and manage permissions across the organization.
