You can run a remote MCP server that exposes tools to MCP clients without requiring authentication, and you can connect to it from both web-based playgrounds and local clients. This setup lets you test, customize, and use your own MCP tools remotely with minimal friction.

How to use

Connect to your remote MCP server from an MCP client or a playground to access your tools. Use the HTTP endpoint to interact with the server from any MCP client that supports remote MCP servers. You can also connect from a local client using a proxy setup that targets the server’s SSE endpoint.

How to install

Prerequisites you need before starting:

Install Node.js and npm from the official Node.js website. This is required to run the MCP server setup command.

Create the remote MCP server project using the following command. This deploys a Cloudflare-based MCP server template that does not require authentication.

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

Additional content

Connect to Cloudflare AI Playground to run your MCP tools directly from a remote client. Open the playground, enter your deployed MCP server URL, and start using your tools right away.

If you want to use a local MCP client like Claude Desktop, you can connect via the mcp-remote proxy. In Claude Desktop, go to Settings > Developer > Edit Config and add the MCP server connection to your configuration.
