Overview

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

A template and deployment method for creating a remote MCP (Model Context Protocol) server on Cloudflare Workers that does not require authentication. It is intended for developers who want to quickly stand up a serverless MCP endpoint with custom tools and access it from remote MCP clients.

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

Deploy using the "Deploy to Workers" button or run 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 from Cloudflare AI Playground by entering the deployed SSE URL, or from Claude Desktop via the mcp-remote proxy.

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

  • Deployable to Cloudflare Workers with one click or a CLI command
  • No authentication required for the MCP server endpoint
  • Exposes tools over Server-Sent Events (SSE)
  • Customizable by adding MCP tools in source code
  • Can be connected from both Cloudflare AI Playground and local MCP clients

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

  • Host custom MCP tools on a globally distributed serverless platform
  • Connect tools from Cloudflare AI Playground without local infrastructure
  • Use as a remote tool provider for Claude Desktop via the mcp-remote proxy
  • Quickly prototype and test new MCP tool sets without authentication overhead

Frequently asked questions

1

How do I deploy this MCP server?

Click the "Deploy to Workers" button or run `npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless` from the command line.

2

How can I add my own tools?

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

3

How do I connect from Cloudflare AI Playground?

Go to the playground URL, enter your deployed MCP server’s SSE URL (e.g., `remote-mcp-server-authless.<your-account>.workers.dev/sse`), and use your tools directly.

4

How do I connect Claude Desktop?

Use the `mcp-remote` npm proxy. In Claude Desktop settings, add a server entry with `command: "npx"`, args including `mcp-remote` and your SSE URL.

5

What runtime / dependencies are required?

The server runs on Cloudflare Workers. Local development requires Node.js and the `npm create cloudflare` CLI. The mcp-remote proxy (for local clients) is an additional npm package.
