Remote MCP Server Authless

You can run a remote MCP server that exposes its tools over HTTP via Cloudflare Workers and also supports local clients through a proxy, enabling you to use your own tools with MCP clients and play with them in environments like the Cloudflare AI Playground or Claude Desktop.

How to use

Connect to your remote MCP server from an MCP client to run your tools anywhere. You can use the Cloudflare AI Playground to experiment with your server’s tools directly in the browser, or you can connect from local clients using the mcp-remote proxy.

How to install

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

How to install

Install and bootstrap a remote MCP server based on the available template. Run the following command to create the MCP server project using the remote-authless Cloudflare template.

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

How to install

Once created, you can deploy or run the server locally according to your Cloudflare setup. The template provides a ready-made remote MCP server that does not require authentication.
