Frequently asked questions
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.
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.
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.
How do I add an MCP server to Claude Code?
Run claude mcp add <name> --transport http "<url>" in your terminal. Claude Code registers the server and discovers all tools immediately.
Can Claude Code run MCP tools in headless mode?
Yes. Claude Code supports non-interactive execution, making it ideal for scripts, cron jobs, and CI/CD pipelines that need MCP tool access.
How do I list all connected MCP servers?
Run claude mcp in your terminal to see all registered servers and their status, or type /mcp inside an active Claude Code session.
