Remote MCP Server Authless

🚀 Deploying an Authentication-Free Remote MCP Server on Cloudflare

This example demonstrates how to deploy an authentication-free remote MCP server on Cloudflare Workers.

🚀 Quick Start

This will assign a URL like remote-mcp-server-authless.<your-account>.workers.dev/sse to your MCP server.

Alternatively, you can use the following command-line instruction to create a remote MCP server on your local machine:

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

✨ Features

Customize Your MCP Server

To add custom tools to your MCP server, define each tool using this.server.tool(...) in the init() method of src/index.ts.

Connect to Cloudflare AI Playground

You can remotely connect to your MCP server from the Cloudflare AI Playground:

1. Visit https://playground.ai.cloudflare.com/.
2. Enter the URL of your remote MCP server (e.g., remote-mcp-server-authless.<your-account>.workers.dev/sse).
3. Now, you can directly use your MCP tools in the Playground!

Connect Claude Desktop to Your MCP Server

You can also connect Claude Desktop to the remote MCP server via the mcp-remote proxy. Follow Anthropic's quick-start guide and add the following content in Settings > Developer > Edit Configuration in Claude Desktop:

{
  "mcpServers": {
    "calculator": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "http://localhost:8787/sse" // or remote-mcp-server-authless.your-account.workers.dev/sse
      ]
    }
  }
}

After restarting Claude, you should see the available tools.
