Remote MCP Server Authless

You can run a remote MCP server that exposes tools for use with any MCP client, including cloud-based playgrounds or desktop clients. This setup lets you connect to a Cloudflare-hosted MCP endpoint and, optionally, run a local proxy to access the server from your own environment.

How to use

Connect to your remote MCP server from an MCP client or the Cloudflare AI Playground to start using your tools. In the playground you simply enter your deployed MCP server URL and you can run available tools directly from the browser interface. You can also connect from a local client by using a proxy configuration that points to the remote server.

How to install

Prerequisites you need locally to install and run the remote MCP server include Node.js and npm. Make sure Node.js is installed on your machine.

1. Create the remote MCP server using the Cloudflare template from the command line.

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

Additional sections

Deployments can be accessed via a URL that Cloudflare provides after you create the server. The remote endpoint URL will resemble remote-mcp-server-authless.<your-account>.workers.dev/sse. You can use this URL directly in MCP clients or in a local proxy configuration to reach the server.

To connect to the remote server from a local environment using a proxy, you can follow the example configuration shown below. This config points an MCP client to the remote server via a proxy tool named mcp-remote. Place this in your client settings and restart the client to enable the tools.
