Authless Cloudflare

You run a remote MCP server that exposes your tools to MCP clients without requiring you to build a custom client. This server lets you define tools, deploy them to a remote endpoint, and connect from clients like the Cloudflare AI Playground or Claude Desktop. Use it to iterate on tool development and share capabilities with your team or automated clients.

How to use

Connect from an MCP client to your remote server to access its tools. You can use the Cloudflare AI Playground to try your MCP tools directly in a browser, or connect from local MCP clients via an mcp-remote proxy. Use the provided remote URL to expose your server and load its tools into the client of your choice.

How to install

Prerequisites: you need Node.js and npm installed on your machine. You also need access to run Cloudflare Workers deployments if you want to host the server remotely. Ensure you have a Cloudflare account ready for deploying the MCP server.

Step-by-step deployment on your machine or CI environment:

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

Additional sections

Configuration and usage options are provided below to help you connect and run tools from remote clients.

Connect to Cloudflare AI Playground

1. Open the Cloudflare AI Playground at the playground URL.
2. Enter your deployed MCP server URL: remote-mcp-server-authless.your-account.workers.dev/sse
3. You can now use your MCP tools directly from the playground.

Connect Claude Desktop to your MCP server
You can connect from Claude Desktop by configuring the MCP server as a remote endpoint. In Claude Desktop, go to Settings > Developer > Edit Config and add the following configuration to use the remote server via the mcp-remote proxy:

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

Restart Claude and you should see the tools become available.
