Cloudflare

You can quickly deploy a remote MCP server on Cloudflare Workers that exposes its tools over SSE without requiring authentication. This setup lets you connect from Cloudflare’s AI Playground or local MCP clients so you can run tools remotely and integrate them into your workflows.

How to use

Connect to your remote MCP server from an MCP client to access and run tools. You can use the built-in Cloudflare AI Playground to try your tools directly, or configure a local client to run tools via the remote server.

How to install

Prerequisites: you need Node.js and npm installed on your machine.

Create the remote MCP server on Cloudflare using the supported template. Run this command in your terminal:

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

Additional setup and usage notes

After deployment, your MCP server will be available at a URL similar to remote-mcp-server-authless.<your-account>.workers.dev/sse. You can copy this URL and use it as the remote endpoint for an MCP client.

Connect from the Cloudflare AI Playground

Open the Cloudflare AI Playground and connect to your deployed MCP server to run tools directly from the playground interface.

Steps:

1. Go to the Cloudflare AI Playground.

2. Enter your deployed MCP server URL: remote-mcp-server-authless.<your-account>.workers.dev/sse.

Connect Claude Desktop to your MCP server

You can also connect a local MCP client to the remote MCP server using the mcp-remote proxy. Configure Claude Desktop to point at the remote SSE endpoint.

In Claude Desktop, go to Settings > Developer > Edit Config and 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
      ]
    }
  }
}
