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

A pre-configured template that deploys a remote MCP (Model Context Protocol) server on Cloudflare Workers without requiring authentication. It is designed for developers who want to quickly expose MCP tools via Cloudflare’s global edge network.

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

Click the "Deploy to Workers" button or run npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless to create the server locally. Customize tools inside the init() method of src/index.ts using this.server.tool(...). Connect from the Cloudflare AI Playground by entering your deployed SSE URL, or from local MCP clients (e.g., Claude Desktop) using the mcp-remote proxy.

FAQ from Building a Remote MCP Server on Cloudflare (Without Auth)

What transport does the server use?

The server uses SSE (Server-Sent Events) transport, exposed at the /sse endpoint of the deployed Worker URL.

Does the server require authentication?

No, this deployment is deliberately without authentication to simplify setup and testing.

How do I add custom tools?

Edit the init() method in src/index.ts and define each tool with this.server.tool(...) following Cloudflare’s MCP tools documentation.

How can I connect from Claude Desktop?

Use the mcp-remote npm package as a proxy: run npx mcp-remote <your-sse-url> and configure Claude Desktop’s mcpServers to use that command.

Where is the server deployed?

It is deployed to a Cloudflare Workers URL like remote-mcp-server-authless.<your-account>.workers.dev/sse.
