Remote MCP Server MCP

You can deploy a remote MCP server on Cloudflare Workers that serves as a flexible, authentication-free MCP backend. This server lets you expose your tools to MCP clients and connect from local or remote clients for testing and integration.

How to use

Connect to your MCP server from an MCP client to run tools and workflows seamlessly. You can access it through the Cloudflare-based remote endpoint and then use your tools from compatible clients without having to run everything locally. For testing or integration, you can also connect from a local client that talks to the remote server via a proxy URL.

How to install

Prerequisites you need before installing: Node.js (with npm) or an environment that can run npm install and npm run commands.

Install and deploy a remote MCP server configured for Cloudflare Workers using the following command:

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

Additional notes

To connect Claude Desktop to this remote MCP server, you can add a local proxy configuration that points to the remote endpoint. Use the following example configuration as a starting point, replacing with your actual remote URL.

{
  "mcpServers": {
    "calculator": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "http://localhost:8787/sse"  
      ]
    }
  }
}

Security and access

This setup demonstrates an authentication-free remote MCP server. If you plan to expose it publicly, consider implementing appropriate access controls and monitoring to prevent misuse.
