Overview

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

A template to deploy a remote MCP (Model Context Protocol) server on Cloudflare Workers without authentication. It uses SSE (Server-Sent Events) transport and is designed for developers who want a quick, publicly accessible MCP endpoint to serve custom tools.

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

Deploy via the “Deploy to Workers” button or run npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless locally. After deployment, the server is available at a URL like remote-mcp-server-authless.<your-account>.workers.dev/sse. Custom tools are added by editing src/index.ts inside the init() method using this.server.tool(...).

Frequently asked questions

What is this server for?

It provides a template to deploy an MCP server on Cloudflare Workers with no authentication required, exposing tools over SSE.

How do I add custom tools?

Define each tool 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 from Claude Desktop?

Install the `mcp-remote` proxy (`npm`), then add a configuration in Claude Desktop’s `mcpServers` that runs `npx mcp-remote <your-sse-url>`.

Does the server require authentication?

No, this template explicitly deploys without authentication – hence “authless”. Anyone with the URL can connect.

What transport protocol does it use?

SSE (Server-Sent Events) – the endpoint is `/sse`.
