概要

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

A template and guide for deploying a remote MCP (Model Context Protocol) server on Cloudflare Workers without requiring authentication. It is intended for developers who want to expose MCP tools over SSE via a serverless Worker.

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 inside the init() method with this.server.tool(...). Connect from Cloudflare AI Playground (enter the deployed SSE URL) or from Claude Desktop using the mcp-remote proxy with the SSE URL in the MCP server configuration.

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

Deploys as a Cloudflare Worker (no auth required).
Uses SSE (Server-Sent Events) transport.
Tools are defined and customized in src/index.ts.
Integrates with Cloudflare AI Playground as a remote MCP client.
Connects to local clients like Claude Desktop via mcp-remote proxy.

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

Exposing MCP tools on the internet without authentication for testing or internal use.
Integrating custom MCP tools with the Cloudflare AI Playground.
Using remote MCP tools from Claude Desktop through a proxy.
Rapidly prototyping and deploying MCP servers using a serverless platform.

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

What transport does the server use?

The server communicates over Server-Sent Events (SSE), as seen in the URL path /sse.

Does the server require authentication?

No, this example explicitly does not include authentication. It is described as "without auth."

How do I add my own tools?

Edit src/index.ts and define each tool inside the init() method using this.server.tool(...).

How can I connect to this server from Claude Desktop?

Use the mcp-remote proxy (available via npx) and set the command in Claude Desktop's MCP configuration to npx mcp-remote <your-sse-url>.

Can I connect from the Cloudflare AI Playground?

Yes. Go to https://playground.ai.cloudflare.com/, enter your deployed SSE URL, and the tools become available.
