Remote

This MCP server hosts remote tools you can run from any client without authentication on Cloudflare Workers. It exposes an HTTP endpoint you can connect to with MCP clients, and you can also run tools locally through a proxy, enabling flexible, centralized tool execution across environments.

How to use

Connect to your remote MCP server from an MCP client or a local proxy to start using tools. You can access the remote server via the provided HTTP URL and you can also route requests through a local proxy to reach the same server.

How to install

Prerequisites: Node.js and npm installed on your machine.

Option A: Deploy directly to Cloudflare with an online deployment flow.

Option B: Run a local setup using the command line helper.

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

Additional notes

Customize the MCP server by adding your own tools in the init() method of src/index.ts using this.server.tool(...).

Connect to the Cloudflare AI Playground to exercise your MCP server from a remote client. Navigate to the Playground, enter your deployed MCP server URL, and start using your MCP tools directly from the playground.

You can also connect Claude Desktop to your remote MCP server via the mcp-remote proxy. Use the following configuration to expose a calculator tool that forwards to your remote server:

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

Tools available in this setup

The server can host multiple tools. A sample tool is named calculator and is wired to use the mcp-remote proxy to reach the remote MCP server. You can define additional tools inside the init() method using this.server.tool(...) to expose more capabilities.
