Remote MCP Server Authless Transport

🚀 Building an Authentication-Free Remote MCP Server on Cloudflare

This example allows you to deploy an authentication-free remote MCP server on Cloudflare Workers.

🚀 Quick Start

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

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

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

✨ Features: Customizing Your MCP Server

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

💻 Usage Examples: Connecting to Cloudflare AI Playground

You can connect to your MCP server through the Cloudflare AI Playground, which serves as a remote MCP client:

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

💻 Usage Examples: Connecting Claude Desktop to Your MCP Server

You can also connect Claude Desktop to the remote MCP server via the mcp-remote proxy.

To connect to your remote MCP server from Claude Desktop, follow Anthropic's Quick Start Guide and go to Settings > Developer > Edit Configuration in Claude Desktop.

Update the configuration as follows:

{
  "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 be able to see the tools available for use.
