How to Use the Nationalize MCP in Cursor

Q: Where do I configure the Nationalize MCP Server for Cursor?

Create a .cursor/mcp.json file in your project's root directory. Add the server configuration there to make it available to Cursor's agent for that project only.

Get nationality predictions from names and inject the data directly into your code with Cursor.

Generate Code with Real Data

The `predict_nationality` tool lets your agent guess a user's country from their name. The real power in Cursor is that the agent doesn't just show you the data; it writes code that uses it. Ask it to build a function that localizes a welcome message, and it will call the tool and generate the code with the real country data. This integration with the MCP server stops you from having to use mock data. You can build and test features that depend on user location context, like dynamic content or regional formatting, with actual API responses from the start.

Enrich User Profiles in Your Editor

When you're working with user data, you can use the `predict_nationality` tool to add a new data point without leaving your editor. Highlight a name in your code, ask the agent to get its nationality, and see the results instantly. It's a fast way to understand the context of the data you're working on. Instead of just seeing a name string, you get a probabilistic idea of where that user might be from, which can inform how you build your next feature.

A Sharper MCP Server for Cursor

This MCP server is simple. It does one thing: it calls the `predict_nationality` tool. There's no extra bloat. It's designed to be a lightweight addition to your Cursor workflow for when you need to quickly infer a user's origin. You can set it up per-project in your `.cursor/mcp.json` file. This means your lead-gen project can have it, but your infra project won't. It keeps your tools relevant to the code you're writing right now.

Setup guide

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Nationalize MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Nationalize transactions." If the MCP tools are loaded correctly, Cursor will call the Nationalize tools automatically. You can also check Settings → MCP for a green status indicator.

Common questions about Nationalize MCP in Cursor

Activate Agent mode and ask it to write a test for a localization function. Tell it to use Nationalize to get a country for a sample name like 'Nakamura' and then assert that the function returns the correct Japanese-specific string.

It works best with last names. Sending a first name like 'John' will give you a wide spread of countries with low probabilities. For better results, stick to surnames.

Create a `.cursor/mcp.json` file in your project's root directory. Add the server configuration there to make it available to Cursor's agent for that project only.

Yes. Just ask the agent to "call Nationalize with the name 'Moretti' and show me the raw JSON." It will execute the tool and print the full response, including the country list and probabilities.

The tool only sends the name you're analyzing to the server. The Vinkius-hosted MCP server processes this request in a sandboxed, memory-only environment. Your data is never written to disk or stored.
