Remote MCP Server (Authless Cloudflare)

You can run a remote MCP server that exposes tools for you to use from MCP clients. This setup lets you deploy a server that serves its tools over HTTP and also supports local proxy-based access from clients like Claude Desktop, enabling you to work with your tools from familiar interfaces without embedding them directly in each client.

How to use

Use your MCP client to connect to the remote server you deploy. You can access the server through the remote URL and start issuing tool commands from any compatible MCP client. For browser-based or remote clients, point them at the HTTP endpoint that serves SSE events for your MCP tools.

How to install

Prerequisites you need before starting:

• Node.js and npm installed on your machine.

Steps to set up the remote MCP server on Cloudflare (authless) and get you running quickly:

Additional sections

Customize your MCP server by adding your own tools. Define each tool inside the init() method of src/index.ts using this.server.tool(...). This lets you extend the server with capabilities you want to expose to clients.

Connect to Cloudflare AI Playground to try out your MCP server from a remote client. Open the Playground, enter your deployed MCP server URL (remote-mcp-server-authless.your-account.workers.dev/sse), and start using your MCP tools directly from the playground.

If you want to run a local client that talks to your remote server via a proxy, you can configure Claude Desktop. In Claude Desktop, go to Settings > Developer > Edit Config and use the following configuration to connect your calculator tool to the remote server.
