Overview

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

This example allows you to deploy a remote Model Context Protocol (MCP) server that doesn't require authentication on Cloudflare Workers. It is designed for developers who want to create custom MCP tools and make them accessible remotely without needing an auth layer.

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

Deploy using the “Deploy to Workers” button or run npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless. Customize tools by editing the init() method in src/index.ts using this.server.tool(...). Connect remote clients like Cloudflare AI Playground by entering your server’s URL (e.g., remote-mcp-server-authless.<your-account>.workers.dev/sse), or connect Claude Desktop via the mcp-remote proxy with the provided JSON configuration.

Frequently asked questions

What does this MCP server do?

It provides a remote MCP server that can be deployed on Cloudflare Workers with no authentication, allowing you to define custom tools accessible over SSE.

How do I deploy this server?

Click the “Deploy to Workers” button or run the `npm create cloudflare` command with the template `cloudflare/ai/demos/remote-mcp-authless`.

How can I add my own tools?

Inside the `init()` method of `src/index.ts`, use `this.server.tool(...)` to define each tool. Refer to the Cloudflare MCP tools documentation for details.

How do I connect to Cloudflare AI Playground?

Go to https://playground.ai.cloudflare.com/, enter your deployed MCP server URL (ending in `/sse`), and you can use the tools directly in the playground.

How do I connect to Claude Desktop?

Install the `mcp-remote` package, then add the server configuration in Claude Desktop’s Developer settings using `npx mcp-remote <your-sse-url>`. Restart Claude to see the tools.

What runtime or dependencies are required?

You need Node.js and npm to use the `npm create cloudflare` command. Deployment requires a Cloudflare Workers account. The server itself runs without authentication.
