Building a Remote MCP Server on Cloudflare (Without Auth)
About
# Building a Remote MCP Server on Cloudflare (Without Auth) This example allows you to deploy a remote MCP server that doesn't require authentication on Cloudflare Workers. ## Get started: [
Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
Building a Remote MCP Server on Cloudflare (Without Auth)Command (node, npx, python, etc.)Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
Instead of using the one-click deploy button, you can clone this repository and deploy it manually to your Cloudflare account.
1. Clone the repository:
git clone <repository-url>
cd <repository-directory>
2. Install dependencies:
npm install
3. Login to Cloudflare:
npx wrangler login
4. Deploy:
npx wrangler deploy
This command will build and deploy your worker. Wrangler will provide you with the URL where your worker is deployed (e.g.,
my-mcp-server.<your-account>.workers.dev/sse).Claude Desktop / Cursor
Paste into your MCP client config file to install this server.

}This example allows you to deploy a remote MCP server that doesn't require authentication on Cloudflare Workers.
Get started:
This will deploy your MCP server to a URL like: remote-mcp-server-authless.<your-account>.workers.dev/sse
Alternatively, you can use the command line below to get the remote MCP Server created on your local machine:
npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless
Deploying to Your Own Cloudflare Worker
Instead of using the one-click deploy button, you can clone this repository and deploy it manually to your Cloudflare account.
1. Clone the repository:
git clone <repository-url>
cd <repository-directory>
2. Install dependencies:
npm install
3. Login to Cloudflare:
npx wrangler login
4. Deploy:
npx wrangler deploy
This command will build and deploy your worker. Wrangler will provide you with the URL where your worker is deployed (e.g.,
my-mcp-server.<your-account>.workers.dev/sse).
Managing Secrets (API Keys)
If your custom tools require API keys or other secrets, you need to configure them securely.
Production Secrets (Cloudflare Dashboard/Wrangler)
For your deployed worker, use Cloudflare's secret management:
1. Using Wrangler:
npx wrangler secret put YOUR_SECRET_NAME
Wrangler will prompt you to enter the secret value. This value will be encrypted and securely stored, accessible only to your worker code.
2. Using Cloudflare Dashboard:
Go to your Worker in the Cloudflare dashboard -> Settings -> Variables -> Environment Variables -> Add Variable. Make sure to click "Encrypt" to store it securely.
Local Development Secrets (.dev.vars)
For local testing using npx wrangler dev, create a file named .dev.vars in the root of your project directory. Do not commit this file to Git. Add your secrets to this file like so:
