1. Set up your project
mkdir cursor-mcp
cd cursor-mcp
npm init -y
npm pkg set type=module
2. Install dependencies
npm install @modelcontextprotocol/sdk
3. Create index.js
import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
import { z } from "zod";
const server = new McpServer({
name: "Hello World",
version: "1.0.0"
});
server.tool("add",
{ a: z.number(), b: z.number() },
async ({ a, b }) => ({
content: [{ type: "text", text: String(a + b) }]
})
);
const transport = new StdioServerTransport();
await server.connect(transport);
4. Add to Cursor
Go to Settings, MCP, and add new MCP server.
The command is node /absolute/path/to/your/index.js. For example node /Users/andyrewlee/mcp-server/index.js.
5. Trigger your MCP by asking Cursor to add 24 and 81
In Agent mode prompt 8 + 24 and watch the add tool in your MCP get triggered.
