Remote MCP Server Cloudflare

You can deploy a remote MCP (Multimodal Conversation Protocol) server that exposes tools over HTTP or via a local proxy, enabling clients to access your MCP tools without authentication. This setup is hosted on Cloudflare Workers and can be connected to from standard MCP clients or from a local proxy workflow.

How to use

You can access your MCP server from different clients to run tools remotely. To start, connect via the Cloudflare AI Playground to try your server directly in a browser. Enter your deployed URL and you can begin using your MCP tools there.

How to install

Prerequisites you need before starting:

• Node.js and npm are installed on your machine.

Follow one of the deployment approaches below to create your remote MCP server.

Option 1: Deploy via Cloudflare template (recommended if you want a hosted remote server)

Run this command to create the server using the Cloudflare template and set up your remote MCP server:

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

After the deployment completes, you will have a remote server URL similar to remote-mcp-server-authless.<your-account>.workers.dev/sse. This is your MCP endpoint for HTTP-based clients.

Option 2: Local initialization for a remote MCP server (alternative)

If you prefer to start the server locally using the Cloudflare setup flow, run the same creation command in your terminal to initialize the project locally.

The deployment outputs a URL you can use in MCP clients and proxies. For example, you can wire this URL into clients or tooling that support the MCP protocol.

Connecting from a local client via a proxy (example)

To connect from Claude Desktop or another local MCP client through the mcp-remote proxy, use a configuration that points to the remote server. The following example shows how you would reference the remote endpoint in a local tool configuration.

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

Connect to Cloudflare AI Playground

You can connect to your MCP server from the Cloudflare AI Playground, which acts as a remote MCP client. Open the Playground, enter your deployed MCP server URL, and start using your MCP tools directly from the playground.

Connect Claude Desktop to your MCP server

You can also connect to your remote MCP server from Claude Desktop by configuring the MCP endpoint in the application. In Claude Desktop, go to Settings > Developer > Edit Config and add the following configuration to enable access to your remote server.

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