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

How do I deploy the server?

Use the “Deploy to Workers” button on 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 my own tools?

Define each tool inside the init() method of src/index.ts using this.server.tool(...).

Can I connect to Cloudflare AI Playground?

Yes. Go to https://playground.ai.cloudflare.com/, enter your deployed MCP server URL (ending in /sse), and then use your tools directly.

How do I connect Claude Desktop to this server?

Install the mcp-remote npm package, then configure Claude Desktop’s mcpServers with "command": "npx", "args": ["mcp-remote", "<your-server-url>/sse"]. Restart Claude to see the tools.

Does the server require authentication?

No. This template deliberately omits authentication. All requests are accepted without credentials.
