Auth0 ships Cross App Access docs: OAuth-based auth for AI agents calling enterprise apps
yenkel · x · 2026-10-11
Auth0 published docs for Cross App Access (XAA), addressing two enterprise pain points: poor IT visibility into agent-to-app data sharing and repetitive OAuth consent prompts.
- XAA implements Identity Assertion Authorization Grant, an in-progress OAuth extension letting apps or AI agents obtain secure tokens from the enterprise IdP to call another app's API on a user's behalf
- IT admins centrally define access controls in a dashboard like the Okta Admin Console, eliminating end-user consent flows
- XAA is the protocol behind MCP's Enterprise-Managed Authorization extension, enabling MCP clients to seamlessly connect to MCP servers
- Author yenkel notes builders wanting XAA support can use Auth0
