This listing does not currently have a tool list to display. This does not mean the server has no tools; check its documentation for supported capabilities.

We auto-extract tools from the README. The maintainer can list them under a ## Tools heading to populate this section.

Overview

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

This server is a template for deploying a Model Context Protocol (MCP) server on Cloudflare Workers that does not require authentication. It is intended for developers who want to quickly create and host remote MCP tools accessible via SSE (Server-Sent Events).

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

Deploy the server using the “Deploy to Workers” button or the command npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless. Customize tools by defining them inside the init() method of src/index.ts with this.server.tool(...). After deployment, connect MCP clients (e.g., Cloudflare AI Playground or Claude Desktop via the mcp-remote proxy) to the server’s SSE URL.

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

  • Deployable to Cloudflare Workers with one click or CLI.
  • No authentication required for connections.
  • Uses SSE transport for remote client access.
  • Customizable by adding your own MCP tools in TypeScript.
  • Works with the Cloudflare AI Playground as a remote client.
  • Can be connected to Claude Desktop via the mcp-remote proxy.

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

  • Hosting AI-powered MCP tools without setting up authentication.
  • Rapid prototyping and testing of MCP servers on a global edge network.
  • Integrating custom MCP tools into the Cloudflare AI Playground.
  • Connecting a remote MCP server to local desktop clients like Claude.

Frequently asked questions

1

How do I deploy this MCP server?

You can deploy by clicking the “Deploy to Workers” button in the README or by running `npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless` on the command line.

2

How do I add custom tools to the server?

Define each tool inside the `init()` method of `src/index.ts` using `this.server.tool(...)`. The server will expose any tools you add.

3

How can I connect to the server from Cloudflare AI Playground?

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

4

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

Use the mcp-remote proxy as a bridge. In Claude Desktop settings, add an MCP server with `command: "npx"` and arguments including `mcp-remote` and the SSE URL of your deployed server.

5

Does this server require any authentication?

No, this MCP server is explicitly built to work without authentication. All connections are open via the public SSE endpoint.
