What is the Descope (Auth Platform) MCP Server?
Connect Descope to your AI agent to manage and test user authentication flows through natural conversation. Descope is a drag-and-drop authentication and user management platform for any application.
What you can do
- OTP Authentication — Initiate and verify One-Time Passwords via Email, SMS, or Voice using tools like
auth_otp_signup_emailandauth_otp_verify_email. - Magic & Enchanted Links — Send secure sign-up/sign-in links and poll for session completion with
auth_magiclink_signup_emailorauth_enchantedlink_poll. - OAuth Integration — Start OAuth flows with providers like Google and exchange codes for active sessions using
auth_oauth_authorize. - Password Management — Handle traditional password-based sign-ups via
auth_password_signup. - Session Verification — Verify tokens and manage the authentication lifecycle directly from your workspace.
How it works
- Subscribe to this server
- Enter your Descope Project ID and optional Management Key
- Start managing your auth flows from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Developers — Test authentication logic and verify OTP/Magic Link flows without leaving the terminal or IDE.
- QA Engineers — Automate the verification of sign-up and sign-in processes through natural language queries.
- Product Managers — Quickly inspect how different auth providers and methods are configured in your project.

Can I start a Google OAuth login flow using this server?
Yes. Use the auth_oauth_authorize tool with 'google' as the provider and specify your redirectURL. The agent will initiate the OAuth flow for you.
What is the purpose of the enchanted link polling tool?
The auth_enchantedlink_poll tool allows the agent to check the status of a pending enchanted link authentication using a pendingRef. It helps determine if the user has clicked the link and completed the session.
