概要

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

This server allows you to deploy a remote Model Context Protocol (MCP) server without authentication on Cloudflare Workers. It is intended for developers who want to expose MCP tools over SSE (Server-Sent Events) from a globally distributed edge network.

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 by editing src/index.ts and adding this.server.tool(...) inside the init() method. Connect to Cloudflare AI Playground or local clients like Claude Desktop via the mcp-remote proxy.

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

Deploy a remote MCP server without authentication
Custom tools defined via the init() method
Connect to Cloudflare AI Playground as a client
Connect to Claude Desktop using mcp-remote proxy
Uses SSE transport on Cloudflare Workers

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

Rapidly prototype and deploy MCP servers on Cloudflare

よくある質問

How do I deploy the server?

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

How do I add my own MCP tools?

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

How do I connect to Cloudflare AI Playground?

Go to https://playground.ai.cloudflare.com/ and enter your deployed MCP server URL (e.g., `remote-mcp-server-authless.<your-account>.workers.dev/sse`).

How do I connect to Claude Desktop?

Install the mcp-remote proxy (`npx mcp-remote`) and add the server URL to Claude Desktop’s MCP configuration under `mcpServers`.

Does this server require authentication?

No, this example explicitly deploys an MCP server without authentication.
