Key features

  1. 01Create a server from a Cloudflare template
  2. 02Run the server locally
  3. 03Test with MCP inspector
  4. 04Deploy to Cloudflare Workers

Use cases

  1. 01Start an MCP server project
  2. 02Test a server during development
  3. 03Deploy a server to a Workers URL

MCP support

The repository guides users through creating and deploying an MCP server. The deployed server is available at a Cloudflare Workers URL.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
  "mcpServers": {
    "cloudflare": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/inspector"
      ]
    }
  }
}
Run commandnpx -y @modelcontextprotocol/inspector

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Packages
npm@modelcontextprotocol/inspector

Tools

No tool list yet

Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

From the project README

Cloudflare MCP

This repository contains the code to create an MCP server and deploy it on Cloudflare workers

Pre-requisites

Before starting this workshop, please ensure you have the following installed:

  • Node.js (version 18 or later) - Download
  • Wrangler CLI - Install with npm install -g wrangler
  • A Cloudflare account for deployments

Getting started

  1. Create a new MCP Server using the Cloudflare template

    npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless

  2. Navigate to the project directory

    cd my-mcp-server

  3. Run this MCP Server locally You can start your MCP Server by running the following command:

    npm start

Testing

Test your MCP Server using MCP inspector To test your MCP Server, you can use the MCP inspector:

npx @modelcontextprotocol/inspector

You will see the inspector with all the tools as seen below

You can also use cloudflare playground which is a platform provided by cloudflare to connect an MCP server

Deploying

You can deploy this server to cloudflare workers with a single command, the first time you might be needed to establish a connection to workers via wrangler but it is straight forward

   npm run deploy

This will deploy your MCP server to a Cloudflare Workers URL like: https://my-mcp-server.<your-account>.workers.dev/sse

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
