What does “without auth” mean?
It means the deployed MCP server does not require any authentication to connect—anyone with the SSE URL can interact with its tools.

Overview
What is Building a Remote MCP Server on Cloudflare (Without Auth)?
This example allows you to deploy a remote MCP server on Cloudflare Workers without requiring authentication. It is intended for developers who want to expose MCP tools over SSE (Server‑Sent Events) to remote clients, with a simple deployment and no built‑in auth layer.
How to use Building a Remote MCP Server on Cloudflare (Without Auth)?
Deploy using the “Deploy to Workers” button or the CLI command npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless. Customize tools by defining each tool inside the init() method of src/index.ts using this.server.tool(...). Connect to the server from the Cloudflare AI Playground by entering the deployed SSE URL, or from Claude Desktop by using the mcp-remote proxy with the same URL in the MCP configuration.
Key features of Building a Remote MCP Server on Cloudflare (Without Auth)
- Deploy a remote MCP server without authentication.
- Uses SSE (Server‑Sent Events) transport.
- Customize tools via the
init()method. - Connect to Cloudflare AI Playground directly.
- Connect to local MCP clients via the
mcp-remoteproxy.
Use cases of Building a Remote MCP Server on Cloudflare (Without Auth)
- Expose MCP tools publicly without needing authentication.
- Quickly prototype and test custom MCP tools on a remote endpoint.
- Integrate MCP tools into Cloudflare’s AI Playground for interactive experimentation.
- Use the server from desktop MCP clients like Claude Desktop via a local proxy.
Frequently asked questions
How do I deploy the server?
Use the “Deploy to Workers” button in the README, or run `npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless` in your terminal.
How do I add custom tools?
Inside `src/index.ts`, define each tool in the `init()` method using `this.server.tool(name, schema, handler)`. See the Cloudflare 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 (e.g., `remote-mcp-server-authless.<your-account>.workers.dev/sse`), and start using your tools directly.
How do I connect Claude Desktop to this server?
Use the `mcp-remote` npm package as a proxy. In Claude Desktop’s MCP configuration, set `command` to `npx`, `args` to `["mcp-remote", "<your-sse-url>"]`, restart Claude, and the tools will appear.
