How do I connect my Hanko instance?

You subscribe to the MCP on Vinkius and enter your Hanko Tenant ID and API Key. Once connected, your AI client can immediately start using the capabilities.

Which AI clients can use this MCP?

This MCP works with any compatible client, including Claude, Cursor, Windsurf, and VS Code.

Can I manage users through my AI agent?

Yes, the MCP includes admin capabilities to create, list, and retrieve user information via the Hanko Admin API.

Does this support passkey transactions?

Yes, it includes capabilities to initialize and finalize passkey-signed transactions for sensitive operations.

Can I delete user credentials?

Yes, you can use the passkey_delete_credential capability to remove specific WebAuthn credentials.

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

Use the passkey_registration_init capability 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 capability (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 capability to provision a new user in your Hanko project by providing a unique user ID.

Connect Hanko Passkey Auth to ChatGPT, Claude and Gemini

Set it up once and it works in ChatGPT, Claude, Cursor, and any other client you love. It all runs safely in the background, so you can relax and focus on what really matters. Manage passwordless identity and WebAuthn flows through your agent.

Waiting for input…

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Real work

What teams actually run

Authentication Debugging

A developer uses the agent to trigger registration flows to ensure the frontend receives the correct WebAuthn options.

User Account Auditing

A security engineer asks the agent to list all credentials for a specific user to check for unauthorized devices.

Transaction Testing

A product team simulates a sensitive payment confirmation by initializing and finalizing a passkey transaction.

Identity Management

An admin uses the agent to quickly create new test users or remove old credentials from the system.

Automate a task

Put Hanko to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

Hanko works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put Hanko to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Connect your client

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 15 capabilities arrive ready to run.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Hanko, so you can see the experience inside your AI.

It does not authenticate your account with Hanko. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.
