Authless Cloudflare

You can run a remote MCP server on Cloudflare Workers that exposes its MCP tools without requiring authentication. This lets you connect from MCP clients or local proxies to access and use the tools you define in your server, securely deployed at a Cloudflare URL.

How to use

Connect to your deployed MCP server from an MCP client or proxy to begin using your tools. You can access the server via its sse endpoint and use the included tools directly from the client. When you open your MCP client, point it to the server URL you deployed and select the tools you want to run.

How to install

Prerequisites you need before installation:

• Node.js installed (recommended LTS)
• npm available in your environment

Step-by-step commands you can run to create and deploy your remote MCP server on Cloudflare:

# Create a new MCP server project using the Cloudflare template
npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless

(Optional) If you prefer to launch directly on your machine without Cloudflare, you can use a local approach described in the template when applicable. After the initial setup, you should have a server ready to configure tools and connect from clients.

## Additional content

Customizing your MCP server lets you add your own tools. Inside your server’s source, define each tool in the init() method using this.server.tool(...). This is where you specify the capabilities your MCP server will expose to clients.

Connect to Cloudflare AI Playground to test or demo your MCP server as a remote client. You can use the same server URL in the playground to interact with your tools.

You can also connect from local MCP clients using a remote proxy. The server URL and its sse endpoint are what you’ll configure in your client so that requests are forwarded correctly to your Cloudflare-hosted MCP server.
