You can deploy a remote MCP server that runs on Cloudflare Workers and expose its MCP tools over HTTP for remote clients and locally via a proxy. This setup is useful for testing, integration with local editors, and connecting from remote clients without hosting a dedicated backend. You’ll get a scalable, serverless MCP instance that can be customized with your own tools and accessed from common MCP clients.

How to use

Connect to your remote MCP server from any MCP client or IDE plugin that supports the standard MCP protocol. You can reach the remote server over HTTP at a public URL and you can also connect from a local client via a proxy configuration that points to the remote server’s SSE endpoint. Once connected, you can load and run the tools you’ve defined in the server and issue prompts or commands to perform automated tasks.

How to install

Prerequisites you’ll need before installation: Node.js and npm installed on your machine. Ensure you have a Cloudflare account if you plan to deploy to Cloudflare Workers. You will also need a text editor to modify configuration files.

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

# After running the command, follow the prompts to deploy to your Cloudflare account.

Additional content

Configure your local clients to connect to the remote MCP server. For example, you can use the following MCP JSON configuration to point a local client at the remote server and enable remote proxy access.

{
  "mcpServers": {
    "calculator": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "http://localhost:8787/sse"  
      ]
    }
  }
}

Remote access and examples

You can deploy the remote MCP server to a public Cloudflare Workers URL like remote-mcp-server-authless.<your-account>.workers.dev/sse and connect to it from your MCP clients or from Cloudflare’s tooling. You can also run a local proxy that forwards to this remote endpoint, enabling you to test with familiar local tooling.
