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."

# How to Make Your AI Agent Enterprise-Ready: Enabling Enterprise-Managed Authorization for Client Apps in Auth0

## Summary

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.

## Context

B2B SaaS teams building AI assistants, developer tools, and autonomous agents need enterprise IT approval for cross-tool data access. Traditional integrations can require disruptive account reconnection prompts or static API keys that security teams reject, creating friction for user adoption and enterprise sales.

## Approach / What changed

Auth0 introduces Early Access Client App capabilities for Cross App Access. Teams enable XAA on an upstream enterprise connection, enable identity assertion grants on target resource connections, and call the standard /oauth/token endpoint for federated exchange. Token Vault retrieves and exchanges ID-JAG assertions with downstream Resource Apps, returning standard access tokens while Auth0 provides logging and applies tenant access rules.

## Takeaways

- Token Vault stores the upstream enterprise refresh token and silently retrieves an ID-JAG, exchanges it with a downstream Resource App, and returns an access token to the application backend.
- Client App setup uses Auth0 Dashboard connection settings and a federated token-exchange request; the downstream API can validate the resulting token without XAA-specific code.
- ID-JAG exchanges are rate-limited to 50% of the tier’s standard Auth API limit, so applications should cache downstream access tokens for their full lifespan.
