Introduction

Auth0 released Auth0 for AI Agents in November 2025.

Recently, AI agents have been rapidly gaining popularity.
However, AI agents often behave in ways that humans would not have predicted.
Therefore, careful attention must be paid to authentication and authorization measures, such as access control and permission granting, when using AI agents.
With Auth0, you can easily implement access control, proxy API calls, asynchronous authorization, and more by using Auth0 for AI Agents.

The main use cases for Auth0 for AI Agents include the following:

• ユーザー認証
• Calling a proxy API
• Coagulation approval
• Access control at the resource level, taking user privileges into consideration.

The main advantages of using a proxy API are as follows:

• Enhanced security
  - Access will be based on the token obtained by specifying the scope, preventing access beyond the granted permissions.
• Proxy operations using AI agents
  - An AI agent can access APIs in the background using tokens, acting as a proxy for user operations.
• Even with asynchronous processing in long-running jobs, token management on the Auth0 side prevents periodic re-authentication.

Operation example

Here, as an operation within the scope of the access permissions agreed upon in advance, we were able to request the retrieval of calendar information and confirm that there was availability in the schedule.

Conversely, if you request an operation that falls outside the scope of your permissions (e.g., retrieving calendar information associated with an unauthenticated user), that request will be blocked.

in conclusion

This page explained how to integrate Google Calendar using Auth0 for AI Agents.
Auth0 for I Agents makes it easy to implement proxy API calls and access control.
