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.

One URL. Every client.

Preview access · not provider authentication

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

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

FAQ

Questions Nationalize owners ask.

    You can use this with any MCP-compatible client, including Claude, Cursor, and Windsurf.

  • 03

    Do I need my own API key?

    You can use it for low-volume testing without a key, but providing a Nationalize.io API key is recommended for higher volumes.

  • 04

    What format is the output in?

    The capability returns a ranked list of ISO country codes and their corresponding probability scores.

  • 05

    Can I check multiple names at once?

    Yes, you can submit up to 10 names at a time to receive predictions.

  • 06

    How many names can I analyze in a single request?

    You can pass a list of up to 10 names to the predict_nationality capability per request. This allows for efficient batch processing of datasets.

  • 07

    What kind of results does the capability return?

    The capability returns a ranked list of ISO 3166-1 alpha-2 country codes (like 'US', 'BR', 'JP') along with a probability score for each, indicating the likelihood of that origin.

  • 08

    Is an API key required to use this server?

    The NATIONALIZE_API_KEY is optional. You can perform basic testing without it, but for higher volume or production use, providing a key is recommended to avoid rate limits.
