Overview

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

This server lets you deploy a Model Context Protocol (MCP) server on Cloudflare Workers that requires no authentication. It is intended for developers who want to create and expose MCP tools remotely via a Cloudflare Workers endpoint.

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

Deploy by clicking the "Deploy to Workers" button or running npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless. Add custom tools inside the init() method of src/index.ts using this.server.tool(...). Connect to clients by supplying the deployed SSE URL (e.g., remote-mcp-server-authless.<your-account>.workers.dev/sse).

Key features of Building a Remote MCP Server on Cloudflare (Without Auth)

  • Deployed on Cloudflare Workers without authentication.
  • Server communicates via SSE endpoint.
  • Easily add custom tools in src/index.ts.
  • One‑click deploy via the Workers button.
  • Works with Cloudflare AI Playground as a remote client.
  • Compatible with Claude Desktop using the mcp-remote proxy.

Use cases of Building a Remote MCP Server on Cloudflare (Without Auth)

  • Expose custom MCP tools from a globally distributed server.
  • Test MCP tools interactively from the Cloudflare AI Playground.
  • Connect MCP tools to Claude Desktop for local‑remote workflows.

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

How do I deploy the server?

Click the "Deploy to Workers" button in the README, or use npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless.

How do I add my own tools to the server?

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

How can I connect the server to Cloudflare AI Playground?

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

How do I connect the server to Claude Desktop?

Install the mcp-remote proxy and add a configuration to Claude Desktop’s MCP settings pointing to your server’s SSE URL (local or remote). Restart Claude to see the tools.

Does this server require any authentication?

No, the README explicitly builds a remote MCP server “without auth”. No authentication is configured.
