How to Use the Numbers API MCP in Cursor

Q: How do I configure the Numbers API in Cursor?

Create a .cursor/mcp.json file in your project root or global directory. Add the server details under the mcpServers block to let your agent call the tools.

Q: Can I share my Numbers API setup with other Cursor developers?

Absolutely. By committing the .cursor/mcp.json file to your Git repository, any teammate opening the project in Cursor can use the same server.

Q: What tools are included in this server?

You get five distinct tools: getdatefact, getmathfact, getrandomfact, gettriviafact, and getyearfact. They cover everything from calendar dates to mathematical properties.

Inject real-time math, date, and historical facts directly into your Cursor code generation.

Inject live historical data into Cursor codebases

The `get_year_fact` tool allows your Cursor agent to fetch historical events for specific years directly while generating test suites or seed data. It acts as an MCP tool to let your editor write files with real-world history. This integration means your agent builds functional prototypes that display genuine historical milestones. You avoid the tedious task of manually searching for filler facts during development.

Test mathematical functions with this MCP Server

Calling `get_math_fact` gives your Cursor agent direct access to mathematical properties of numbers to verify algorithms or generate assertions. It queries the server and inputs the resulting facts straight into your active file. Setting up this MCP Server in your `.cursor/mcp.json` file ensures that every workspace session has access to these math lookup capabilities. Your agent writes smarter code because it has access to real data.

Populate mock databases with random trivia

Your Cursor agent uses `get_random_fact` and `get_trivia_fact` to generate engaging placeholder text for UI components. You no longer have to rely on repetitive lorem ipsum blocks when building card layouts. Because Cursor operates in agent mode, it reads these trivia strings and formats them into your JSON or HTML templates. The final layout looks polished and realistic from the start.

Setup guide

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