Remote MCP Server (Authless Cloudflare)

Exposes remote MCP tools accessible via HTTP URL or local stdio proxy for Cloudflare and Claude Desktop clients.

Installation

Add the following to your MCP client configuration file.

Configuration

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

You can run a remote MCP server that exposes tools over HTTP or locally via stdio, enabling you to connect with MCP clients like the Cloudflare AI Playground or Claude Desktop. This setup lets you run tools remotely and access them from different clients with minimal configuration.

How to use

Connect your MCP server to a client to start using its tools. You can test and run tools from the Cloudflare AI Playground or connect via the local Claude Desktop workflow. For the Cloudflare Playground, go to the Playground and enter your deployed MCP server URL to start issuing tool prompts directly from the browser.

If you prefer a local client workflow, you can connect Claude Desktop to your remote MCP server using the mcp-remote proxy. In Claude Desktop, open Settings > Developer > Edit Config and use the snippet below to point to your server. This enables the same tools locally in Claude without exposing your server beyond the configured endpoint.

Example deployment URL once you deploy the server on Cloudflare Workers looks like: remote-mcp-server-authless.<your-account>.workers.dev/sse. You can also run the same server locally via a command that creates the remote MCP server on your machine and serves it at the specified address.

How to install

Prerequisites: Install Node.js and npm on your workstation. You will also need access to a Cloudflare account if you plan to deploy to Cloudflare Workers.

Step 1: Install and bootstrap the remote MCP server project locally by creating a new project using the Cloudflare template.

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

Step 2: If you want to deploy directly to Cloudflare, follow the deployment prompts to publish your MCP server to a URL like remote-mcp-server-authless.<your-account>.workers.dev/sse.

Step 3: To customize the tools exposed by the MCP server, edit the init() method in src/index.ts and add each tool with this.server.tool(...). Save your changes and rebuild if needed before running.

Additional content from this setup

Connect to Cloudflare AI Playground by entering your deployed MCP server URL (remote-mcp-server-authless.<your-account>.workers.dev/sse) in the Playground client. This lets you experiment with your MCP tools directly in the browser without additional configuration.

Connect Claude Desktop to your MCP server using the mcp-remote proxy. In Claude Desktop, go to Settings > Developer > Edit Config and add the following server configuration to your mcpServers section. This enables Claude to use your remote MCP server tools as if they were local.
