create-mcp

View original on GitHub

A CLI tool that sets up a Model Control Protocol (MCP) server and deploys it to Cloudflare Workers so you can start making new tools for your Cursor Agent in minutes.

Just write TypeScript functions with JSDoc comments to give your agent MCP tools.

Prerequisites

Wrangler CLI installed and logged in with your Cloudflare account.
Claude Desktop App installed.

Instructions

To scaffold and deploy a new MCP server, just run:


bun create mcp

You can also pass a name to the server: bun create mcp <server-name>.

What this CLI does

Clones the template worker repository into <current-dir>/<server-name>
Installs dependencies
Initializes a Git repository
Deploys a Hello World MCP server to your Cloudflare account
Adds it to Claude Desktop
Copies the MCP server command to your clipboard so you can paste it into Cursor

Development

To start hacking on your MCP server:


cd <server-name>
bun dev

How to Use

Just add functions to the MyWorker class in src/index.ts. Each function will compile into an MCP tool.

For example:


/**
 * A warm, friendly greeting from your new Workers MCP server.
 * @param name {string} the name of the person we are greeting.
 * @return {string} the contents of our greeting.
 */
sayHello(name: string) {
    return `Hello from an MCP Worker, ${name}!`;
}

The first line is the tool’s description.
The @param tags are the tool’s params, with types and descriptions.
The @return tag is the tool’s return value, with its type.

Deploying Changes

Redeploy the worker:


bun run deploy

Reload your Cursor window.

Now you can ask your agent to use the new tool!

Why Cloudflare Workers?

Honestly, vibes, great DX, and blazing fast deployments.

I don’t like running MCP servers locally, and I’m pretty sure you don’t either. Now we don’t have to run node processes to use simple MCP tools in Cursor that call APIs.

All you have to do is write functions. Put your descriptions and params in JSDoc comments and it just works.
