Headless 2FA verification via Claude Code

The `auth` tool initiates out-of-band push authentication requests directly from your command line. This MCP Server lets you trigger these prompts right from your shell, then polls `auth_status` to confirm you approved the prompt. You can easily pipe these checks into your deployment scripts or run them before running a dangerous database migration. It brings interactive multi-factor verification straight into your headless CLI workflow.

Command-line user audits and provisioning

The `list_users` tool queries your Duo database to identify inactive accounts from your terminal. Tell Claude Code to scan your system, and it will use this endpoint to find inactive accounts, then send them to the recycle bin using `trash_users`. If you need to onboard a batch of external contractors, you can feed Claude Code a raw text list and it will execute `bulk_create_users` to register them in seconds. If a contractor returns, the agent can quickly run `restore_users` to reactivate their profile.

Diagnose Duo Security API connectivity instantly

The `ping_auth` tool performs a liveness check to verify the Duo Auth API is reachable. Claude Code can run this to verify the Duo Auth service is up, then execute `check_auth` to validate your HMAC signatures and integration keys. This instant diagnostics capability saves you from digging through API documentation or writing curl commands with complex signature headers. You get immediate, actionable feedback directly in your terminal.
