Overview

What is Building a Remote MCP Server on Cloudflare (Without Auth)?

This example demonstrates how to deploy a remote MCP (Model Context Protocol) server on Cloudflare Workers that requires no authentication. It is intended for developers who want to quickly set up a remote MCP server and connect it to clients like the Cloudflare AI Playground or Claude Desktop.

How to use Building a Remote MCP Server on Cloudflare (Without Auth)?

Deploy using the "Deploy to Workers" button or the CLI command npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless. After deployment, the server is available at a URL like remote-mcp-server-authless.<your-account>.workers.dev/sse. Customize by adding tools inside the init() method of src/index.ts with this.server.tool(...). Connect to clients by entering the SSE endpoint URL.

Key features of Building a Remote MCP Server on Cloudflare (Without Auth)

Provides a one-click deploy button or CLI setup.
Supports custom tool definitions via this.server.tool(...).
Connects directly to Cloudflare AI Playground as a remote MCP client.
Works with Claude Desktop through the mcp-remote proxy.

Use cases of Building a Remote MCP Server on Cloudflare (Without Auth)

Quickly prototyping an MCP server without setting up authentication.
Integrating MCP tools into Cloudflare's AI Playground for testing.
Connecting a local MCP client (e.g., Claude Desktop) to a cloud-hosted server.
Sharing a simple, public MCP server for demo or development purposes.

Frequently asked questions

How do I deploy this MCP server?

Use the "Deploy to Workers" button from the README, or run `npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless` in your terminal.

How can I add my own tools?

Each tool is defined inside the `init()` method of `src/index.ts` using `this.server.tool(...)`. Refer to Cloudflare’s MCP tools documentation for details.

How do I connect this server to Cloudflare AI Playground?

Go to https://playground.ai.cloudflare.com/, enter your deployed SSE URL (e.g., `remote-mcp-server-authless.<your-account>.workers.dev/sse`), and you can use the tools from the playground.

How do I connect Claude Desktop to this remote MCP server?

Install the `mcp-remote` proxy and configure Claude Desktop’s MCP settings with the `mcp-remote` command pointing to your server’s SSE URL. A sample configuration is provided in the README.

Does this server require authentication?

No, the title explicitly states "Without Auth". The server is deployed with no authentication mechanism.
