How to Use the Haversine Distance Engine MCP in Cursor

Q: How do I configure the Haversine Distance Engine in Cursor?

You add the server configuration to your project's .cursor/mcp.json file. Cursor will automatically detect the server and make the tool available in your chat panel.

Let Cursor call the Haversine Distance Engine to inject real point-to-point calculations directly into your active codebase.

Perplexity

Generate real geographic tests inside Cursor

The `calculate_distance` tool lets Cursor generate real test assertions using actual coordinate math. Instead of hardcoding fake numbers, ask Cursor to write the test using live outputs. The editor uses this tool to run the Haversine formula on your coordinates. It then writes the exact resulting miles or kilometers directly into your test suite.

Run direct coordinate calculations in Agent mode

While checking a routing bug in your editor, you can call the `calculate_distance` tool via this MCP server in Agent mode to verify coordinates on the fly. You highlight a pair of coordinates and ask the Cursor agent to calculate the distance. You get the exact distance in kilometers and miles written directly into your chat or inline edit window. This keeps you focused on fixing the bug instead of writing throwaway scratchpad scripts.

Validate coordinate inputs during code generation

The `calculate_distance` tool validates geographic inputs while Cursor generates your routing code. This MCP Server lets the editor test its code against real coordinate pairs. The model calls the tool to ensure the generated code handles boundary cases correctly. You end up with more reliable code because the editor tests its work before you even run it.

Setup guide

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

Common questions about Haversine Distance Engine MCP in Cursor

You add the server configuration to your project's `.cursor/mcp.json` file. Cursor will automatically detect the server and make the tool available in your chat panel.

Yes, when you use Agent mode, Cursor can call the tool to get real distance values. This lets the editor insert actual calculated numbers instead of placeholder values.

No, the mathematical calculations are executed locally. Cursor talks to the server over a local connection, so you can calculate distances even when you are offline.

The tool returns the distance in both kilometers and miles. Cursor can read both values and use whichever unit matches your code's requirements.

Your coordinates are processed locally on your machine by the server. The data is never sent to any external tracking or logging services, keeping your location data secure.
