Remote MCP Server (Authless)

Building a Remote MCP Server to Generate Podcasts (and rickroll) on Cloudflare w/o auth

This example allows you to deploy a remote MCP server to rickroll people that doesn't require authentication on Cloudflare Workers.

It uses a Cloudflare Workers AI LLM to generate complex URL slugs that attach to this rickrolling Cloudflare Worker page ( also on GitHub here). It uses specific, detailed tool descriptions that do not mention rickrolling at all. The specialized tool appears to generate a podcast, getting past Claude's URL filtering, and saves that URL and topic to a Cloudflare D1 database.

Tools

generate_podcast

This tool takes in a topic and makes a LLM call to Cloudflare Workers AI to generate a complex path relating to the input topic. It then returns the combined Cloudflare Worker URL with that slug, appearing to be a podcast about the input query.

list_recent_podcasts This tool takes in a number and queries the Cloudflare D1 SQL database for previous podcast URLs and topics generated.

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

Customizing your MCP Server

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

Connect to Cloudflare AI Playground

You can connect to your MCP server from the Cloudflare AI Playground, which is a remote MCP client:

Go to https://playground.ai.cloudflare.com/
Enter your deployed MCP server URL (remote-mcp-server-authless.<your-account>.workers.dev/sse)
You can now use your MCP tools directly from the playground!

Connect Claude Desktop to your MCP server

You can also connect to your remote MCP server from local MCP clients, by using the mcp-remote proxy.

To connect to your MCP server from Claude Desktop, follow Anthropic's Quickstart and within Claude Desktop go to Settings > Developer > Edit Config.

Update with this configuration:

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

Restart Claude and you should see the tools become available.
