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 enables deployment of a remote MCP (Model Context Protocol) server that requires no authentication on Cloudflare Workers. It is intended for developers who want to expose MCP tools publicly without a login barrier.

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

Deploy by clicking the "Deploy to Workers" button or run npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless locally. Customize tools by editing src/index.ts inside the init() method using this.server.tool(...). Connect to the Cloudflare AI Playground (https://playground.ai.cloudflare.com/) by entering the deployed SSE URL, or connect Claude Desktop via the mcp-remote proxy with the JSON configuration shown in the README.

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

  • Deployed as a Cloudflare Worker without authentication.
  • Provides an SSE endpoint (/sse) for remote MCP clients.
  • Tools are customizable directly in src/index.ts.
  • Integrates with Cloudflare AI Playground out of the box.
  • Supports local MCP clients through the mcp-remote proxy.

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

  • Exposing MCP tools to the public internet without user login.
  • Connecting a remote MCP server to Cloudflare AI Playground for testing.
  • Using MCP tools from Claude Desktop via a proxy.
  • Quickly prototyping and iterating on MCP servers using Cloudflare’s global network.

Frequently asked questions

1

How do I deploy this MCP server?

Click the "Deploy to Workers" button in the README, or run the `npm create cloudflare` command with the provided template.

2

What dependencies are required?

You need Node.js and npm to create the project locally; the deployed Worker runs on Cloudflare’s runtime. For local clients, the `mcp-remote` npm package is needed.

3

Where does my data live?

All MCP server logic runs on Cloudflare Workers, and data is managed within the Worker’s environment. No persistent storage is configured by default.

4

How is the server accessed?

It listens for SSE connections at the deployed Workers URL (e.g., `remote-mcp-server-authless.<your-account>.workers.dev/sse`). No authentication is enforced.

5

Can I use this server with local MCP clients like Claude Desktop?

Yes, by running the `mcp-remote` proxy locally and pointing your client to the proxy’s address, as shown in the README’s JSON configuration example.
