Hanko (Passkey Auth)

What is the Hanko (Passkey Auth) MCP Server?

Connect your Hanko instance to any AI agent to streamline passkey-based authentication and user management. This server provides a comprehensive interface for WebAuthn flows and administrative user operations.

What you can do

  • Passkey Lifecycle — Initialize and finalize WebAuthn registration and login flows for secure, passwordless access.
  • Credential Management — List and delete registered WebAuthn credentials for specific users.
  • User Administration — Create, retrieve, and list users and their associated credentials via admin tools.
  • Transaction Security — Initialize and finalize passkey-signed transactions for sensitive operations like payments.
  • Session Validation — Publicly validate sessions and retrieve JWKS for token verification.

How it works

  1. Subscribe to this server
  2. Enter your Hanko Tenant ID and API Key
  3. Start managing identity flows from your MCP-compatible client

Who is this for?

  • Developers — quickly test and debug WebAuthn registration and login flows without manual API calls.
  • Security Engineers — audit user credentials and manage identity access policies through a conversational interface.
  • Product Teams — simulate and verify user onboarding and transaction signing workflows.

How do I start a new passkey registration for a user?

Use the passkey_registration_init tool with the user's ID and username. This will return the necessary WebAuthn options to be used on the client side.

02

Can I view all WebAuthn credentials associated with a specific user?

Yes, you can use the passkey_list_credentials tool (or admin_list_user_credentials for admin access) to retrieve a list of all registered passkeys for any user ID.

03

Is it possible to create a user directly through the AI agent?

Absolutely. Use the admin_create_user tool to provision a new user in your Hanko project by providing a unique user ID.

04

How does the Vercel AI SDK connect to MCP servers?

Import createMCPClient from @ai-sdk/mcp and pass the server URL. The SDK discovers all tools and provides typed TypeScript interfaces for each one.
