How to Use the Nubarium MCP in Cursor

Q: How do I add the Nubarium MCP Server to my Cursor project?

Create a .cursor/mcp.json file in your project root and define the server under the mcpServers key. Once saved, Cursor Agent will automatically detect the six validation tools for your coding sessions.

Q: Do my team members need separate keys?

If you commit the .cursor/mcp.json configuration to your repository, your team can use the shared Vinkius endpoint. Each developer will access the verification tools using the authenticated connection.

Generate code using live Mexican identity and corporate data directly inside Cursor Agent.

Validate Tax IDs While Coding in Cursor

Your agent runs `validate_mex_rfc` to test tax ID validation logic with live data while coding in Cursor. Write your checkout or onboarding code and let the editor verify it against official records. If your application requires verifying signing authority, have the Cursor Agent run `validate_mex_legal_representative`. It tests your code against actual RFC and CURP pairings to confirm legal representation status.

Build Registries with Live Mexican Corporate Data

Your editor calls `search_mex_companies` to pull real Mexican enterprise profiles into your active files. When building supplier databases, let Cursor locate businesses. You do not have to guess field types or write manual scrapers when this MCP Server is active in your editor.

Verify CURPs and Monitor Usage in Cursor

Your workspace invokes `get_api_usage` to monitor development costs and track query counts. Ask the agent to check your limits directly inside the Cursor terminal panel. To run a test verification, feed a target CURP to the chat. Cursor calls `validate_mex_curp` to verify names and birthdates against the central Mexican registry.

Setup guide

Set up Nubarium MCP in Cursor

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 Nubarium 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 Nubarium transactions." If the MCP tools are loaded correctly, Cursor will call the Nubarium tools automatically. You can also check Settings → MCP for a green status indicator.
