Remote MCP Server Authless MCP Server

Provides a remote MCP server for tool execution via Cloudflare Workers and local proxies.

Installation

Add the following to your MCP client configuration file.

Configuration

{
  "mcpServers": {
    "caradocnava-remote-mcp-server-authless": {
      "url": "https://remote-mcp-server-authless.<your-account>.workers.dev/sse"
    }
  }
}

You can run a remote MCP server that exposes its tools over an HTTP endpoint or locally via a small MCP proxy, enabling you to use your tools from standard MCP clients. This setup is designed for Cloudflare Workers and includes a quick path to connect from Cloudflare AI Playground and Claude Desktop.

How to use

You can access your remote MCP server from an MCP client to run your tools directly. Use the Cloudflare AI Playground to interact with your MCP server by entering the deployed server URL and invoking your tools within the playground environment.

To connect from Claude Desktop, configure the MCP proxy as shown in the next section and restart Claude so your tools become available. When you run a tool, the MCP server will execute it and return results to your client, enabling you to chain tools, test ideas, and iterate quickly.

How to install

Prerequisites you need before installing this MCP server are Node.js and npm. Ensure you have a Cloudflare account if you plan to deploy to Cloudflare Workers.

Install and scaffold the remote MCP server with the following command to create a new project configured for an authless Cloudflare deployment:

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

Additional content

Customize your MCP server by adding your own tools inside the init() method of src/index.ts using this.server.tool(<tool-configuration>). This lets you expose new capabilities directly to MCP clients without altering client code.

Connect to the Cloudflare AI Playground to test and run your MCP tools remotely. Open the Playground, enter your deployed MCP server URL (for example remote-mcp-server-authless.your-account.workers.dev/sse), and start invoking tools to verify behavior.

If you want to connect from a local MCP client via the mcp-remote proxy, you can configure Claude Desktop to load your tools by editing the MCP server configuration in Settings > Developer. Example configuration is shown below.
