Remote MCP Server (Authless Cloudflare)

This remote MCP (Meta Custom Prompt) server lets you expose a tools-based interface that clients can connect to over HTTP, enabling you to run and compose tools from a cloud-hosted MCP setup. It is useful when you want quick access to a set of tools without managing local infrastructure, and it supports connecting from MCP clients and remote playground environments.

How to use

You can connect to this MCP server from any compatible MCP client or playground. Use the remote URL to access the server’s SSE endpoint and interact with the available tools through your client of choice. You can also connect from local clients by configuring the client to reach the provided remote URL.

How to install

Prerequisites: ensure you have Node.js and npm installed on your machine.

Install or deploy the remote MCP server using the Cloudflare deployment flow shown below. You will be deploying to a Cloudflare Workers URL that hosts the MCP server with authless access.

npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless

Additional sections

Connect to Cloudflare AI Playground to use the MCP server directly from a remote client. Steps: 1) Open the Playground, 2) Enter your deployed MCP server URL, 3) Interact with the MCP tools from the playground interface.

Connect Claude Desktop to your remote MCP server by configuring Claude Desktop to point to the remote URL via the mcp-remote proxy. Use the following configuration in Claude Desktop under Settings > Developer > Edit Config to expose the remote server tools locally.
