Overview
What is Building a Remote MCP Server on Cloudflare (Without Auth)?
This example enables you to deploy a remote Model Context Protocol (MCP) server on Cloudflare Workers without requiring authentication. It provides an SSE endpoint for remote MCP clients and is intended for developers who want to expose MCP tools over the internet without auth.
How to use Building a Remote MCP Server on Cloudflare (Without Auth)?
Deploy by clicking the “Deploy to Workers” button or by running npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless. Customize tools inside the init() method of src/index.ts using this.server.tool(...). Connect to the server via its URL (remote-mcp-server-authless.<your-account>.workers.dev/sse). Use it with Cloudflare AI Playground or with local MCP clients (e.g., Claude Desktop) through the mcp-remote proxy.
Key features of Building a Remote MCP Server on Cloudflare (Without Auth)

- No authentication required for the server
- Uses SSE (Server-Sent Events) transport
- Fully customizable tools via
this.server.tool() - Works with Cloudflare AI Playground as a remote MCP client
- Connects to local MCP clients via
mcp-remoteproxy
Use cases of Building a Remote MCP Server on Cloudflare (Without Auth)
- Exposing custom MCP tools to remote clients without auth overhead
- Integrating MCP tools with the Cloudflare AI Playground from any device
- Connecting a remote MCP server to Claude Desktop for AI-assisted workflows
- Rapid prototyping and testing of MCP tool definitions
Frequently asked questions
Does the server require authentication?
No. This example explicitly omits authentication features. It is designed for scenarios where auth is not needed.
What transport protocol does the server use?
It uses SSE (Server-Sent Events) as the transport. The endpoint ends with `/sse`.
Where does the server run?
The server runs on Cloudflare Workers, a global edge computing platform. Data and code are executed on Cloudflare’s infrastructure.
Can I connect this server to local MCP clients like Claude Desktop?
Yes. Use the `mcp-remote` proxy (npm package) in your client configuration to point to the remote SSE URL. Claude Desktop configuration example is provided in the README.
