FAQ

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 does Pydantic AI discover MCP tools?

Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.

Does Pydantic AI validate MCP tool responses?

Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.

Can I switch LLM providers without changing MCP code?

Absolutely. Pydantic AI abstracts the model layer. your Hanko (Passkey Auth) MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
