Remote MCP Server (Authless Cloudflare)

You build a remote MCP server on Cloudflare that serves as an autonomous, authentication-free MCP endpoint. You can deploy it quickly, connect from an MCP client like a Cloudflare AI Playground or Claude Desktop, and customize it by adding your own tools. This server pattern is useful for quickly prototyping toolchains and experimenting with remote command execution in a controlled MCP environment.

How to use

Once your remote MCP server is deployed, you can access it from MCP clients to run your tools. In the Cloudflare AI Playground you connect by entering the deployed server’s SSE URL and then invoke the available tools directly from the playground interface. You can also connect from local MCP clients by pointing them at the server’s SSE URL or using a local proxy configuration. If you want to reuse the same server from Claude Desktop, you can point the client to the remote server and enable the tools in Claude after you restart the app.

How to install

Prerequisites you need before starting:

• Node.js and npm installed on your machine
• Access to a terminal or shell

Step by step, run these commands to create and deploy the remote MCP server instance on Cloudflare:

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

Additional setup after deployment

After deployment, you will have a remote MCP server URL that looks like remote-mcp-server-authless.<your-account>.workers.dev/sse. You can connect to this URL from Cloudflare AI Playground or from your local MCP clients.
