Auth0 is launching Early Access for Client App, or Requesting App, capabilities that support Cross App Access (XAA) for AI assistants, developer tools, and autonomous agents. In the Enterprise-Managed Authorization (EMA) model, an employee’s corporate SSO login can authorize access to external APIs or Model Context Protocol (MCP) servers through the IETF Identity Assertion Authorization Grant (ID-JAG) draft specification. Auth0’s Token Vault brokers the multi-hop exchange: it stores an upstream enterprise refresh token, retrieves a short-lived ID-JAG, exchanges it with the downstream Resource App, and returns a standard access token to the backend. Setup uses dashboard toggles and connection settings, followed by a standard /oauth/token federated exchange, while the API requires no XAA-specific changes. The release also describes audit logging, enterprise IdP policy control, OIN distribution, and caching downstream tokens because ID-JAG exchanges are rate-limited to 50% of the tier’s standard Auth API limit.
