Remote

You can run a remote MCP server that exposes tools over a live endpoint, allowing you to build and access your tools from clients like the Cloudflare AI Playground or Claude Desktop. This setup enables you to deploy an authless remote MCP server on Cloudflare Workers and connect to it from local or cloud-based MCP clients.

How to use

You can connect to your remote MCP server from MCP clients to use your tools in real time. Start by deploying the server to a public URL, then connect from the client you prefer.

How to install

Prerequisites you need before installation:

• Node.js and npm installed on your machine.

Follow these concrete steps to set up and run the remote MCP server.

# Option 1: Deploy to Cloudflare Workers using their CLI template
npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless

Additional sections

Connect to Cloudflare AI Playground to try your MCP server from a remote client. Open the Playground, then enter the deployed server URL to begin using your MCP tools directly in the playground.

If you want to connect from a local MCP client such as Claude Desktop, you can configure the client to use the remote MCP server. The configuration example below shows how to point your client to the remote endpoint.
