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:

This will deploy your MCP server to a URL like: remote-mcp-server-authless..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(...).

Tavily News Search Tool

This MCP server includes a news search tool powered by the Tavily API. To use it:

  1. Sign up for a Tavily API key at tavily.com
  2. Add your API key to the wrangler.jsonc file in the "vars" section:
    "vars": { "TAVILY_API_KEY": "your-actual-api-key" }
  3. For production, it's recommended to use Cloudflare Workers Secrets instead:
    npx wrangler secret put TAVILY_API_KEY

News Search Response Format

The searchNews tool returns news results in a structured text format:

Here are the top {N} {topic} news results for "{query}" (time range: {timeRange}):

1. {Title}
   {URL}
   {Content snippet}

2. {Title}
   {URL}
   {Content snippet}
...

To parse these results into JSON in your client application, you can extract the information from the formatted text response.

Connect to Cloudflare AI Playground

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

  1. Go to https://playground.ai.cloudflare.com/
  2. Enter your deployed MCP server URL (remote-mcp-server-authless..workers.dev/sse)
  3. 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.
