Remote

You can run a remote MCP server that exposes tools over an HTTP endpoint and connect to it from MCP clients like the Cloudflare AI Playground or Claude Desktop. This setup is useful for hosting your own tools and making them available to a centralizedMC P workflow without requiring authentication on the server side.

How to use

Connect your MCP client to the remote server using the provided HTTP URL. The server serves its tools over a dedicated SSE endpoint, allowing you to invoke tools and receive results in real time.

How to install

Prerequisites you need before starting:

• Node.js (LTS version) installed on your machine
• npm installed with Node.js

Step-by-step commands to create and run your remote MCP server instance:

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

Additional content

Connect to the Cloudflare AI Playground to interact with your MCP server from a remote client.

1. Open the Cloudflare AI Playground at the provided URL.

2. Enter your deployed MCP server URL (for example: remote-mcp-server-authless.your-account.workers.dev/sse).

3. You can now use your MCP tools directly from the playground.

Connecting Claude Desktop to your MCP server

You can also connect to your remote MCP server from Claude Desktop by using the mcp-remote proxy. Follow Anthropic's Quickstart and update Claude Desktop Settings.
