Short answer

How can I use AI to test my auth flows?

Your AI client uses FusionAuth tools to execute logins, trigger MFA prompts, and grab JWTs. You get a way to programmatically verify that your identity logic holds up under different session scenarios.

Test outcomes

What you get

The results of your AI-driven testing.

VALIDATION

Verified login paths

The agent runs through the full login sequence. You get confirmation that credentials and identity providers work as expected.

SECURITY

MFA flow checks

The AI triggers multi-factor challenges. You see if your MFA requirements are actually being enforced.

TOKENS

JWT integrity

The agent requests and inspects tokens. You can verify that claims and expiration logic are correct.

MANUAL

Human intervention

The AI stops when it hits a physical MFA prompt or a CAPTCHA. You step in to finish the sequence.

The workflow

What your AI does when the test arrives.

The AI acts as a simulated user to walk through your identity lifecycle.

  1. Simulate user entry

    The agent attempts to enter the system using provided credentials or external providers.

    loginidp_login

  2. Trigger security hurdles

    The AI initiates the second factor of authentication to test your protection layers.

    start_mfamfa_login

  3. Verify session tokens

    The agent requests new tokens to ensure the identity service issues valid credentials.

    issue_jwt

  4. Validate token lifecycle

    The AI checks if the system correctly handles token updates.

    refresh_jwt

  • Run a login for user 'test_user@example.com' and tell me if the JWT is issued.

  • Trigger an MFA sequence for my test account and wait for my input.

  • Use the idp_login tool to check if the Google provider is responding.

  • Try to refresh a JWT for a session to see if the claims remain consistent.

FAQ

How this task behaves

  • 01

    Can the AI bypass MFA automatically?

    No. The AI can trigger the MFA request, but it cannot bypass the physical requirement for a code or biometric check.

  • 02

    Can the AI change my user passwords?

    No. The tools are limited to login, MFA, and token management. It cannot modify user account data or passwords.

  • 03

    Does the AI see my FusionAuth admin password?

    No. Your credentials are encrypted and handled by the MCP; the AI only interacts with the tools provided.

  • 04

    Can I test external identity providers?

    Yes, you can use the tool to simulate logins through configured identity providers.

  • 05

    Will the AI create new users in my database?

    No. There are no tools available in this MCP to create or delete user records.
