Anthropic expanded its Enterprise-Managed Authorization (EMA) capability, introduced in June, by allowing Claude itself to issue identity assertions for MCP service access. This eliminates the need for employees to manually sign in and authorize individual plugins or services. The feature simplifies enterprise deployment by leveraging existing identity providers and reduces authentication friction while maintaining security through organizational membership verification.

Key points

  • Claude can issue signed identity assertions for MCP services
  • Eliminates manual sign-in for each approved plugin or service
  • Builds on June's EMA extension to Model Context Protocol
