How to Use the Duo Security (Two-Factor Authentication API) MCP in Cursor

Q: How do I add the Duo Security (Two-Factor Authentication API) tools to Cursor?

Create a .cursor/mcp.json file in your project root. Define the server with your Duo credentials, and Cursor will automatically load the tools into your active workspace.

Q: Can Cursor verify if a user is locked out of Duo Security (Two-Factor Authentication API)?

Yes, Cursor can check a user's status. The agent calls preauth to see if the user is active, bypassed, or locked out before attempting any 2FA push.

Code and test your Duo Security 2FA workflows directly inside Cursor using live API tools.

Test Duo API integration keys directly in Cursor Agent

Stop writing throwaway test scripts to verify your HMAC signatures. With this MCP Server running in Cursor, your agent runs `check_auth` to instantly validate your integration credentials. You can write your backend authentication logic while the editor tests live connection states using `ping_auth`. The agent injects real API payloads directly into your open files, making mock data obsolete.

Clean up test accounts and users inside your workspace

Managing active sandboxes during development is tedious. Cursor uses `list_users` to find your current test profiles and lets you run `trash_users` to clean up old accounts. If you accidentally purge the wrong developer account, the agent executes `restore_users` to bring them back. This keeps your development tenant clean without forcing you to open a browser window.

Generate functional 2FA code with real Duo endpoints

Tell Cursor to write a login handler, and the agent will use `preauth` to inspect user status and decide which factors to present. It writes the code using real, live responses from your Duo tenant. The agent then tests the generated login flow by calling `auth` and waiting on `auth_status`. You get a fully functional, verified codebase written against your actual security configuration.
