Remote Authless MCP Server on Cloudflare

Overview: What is the Remote Authless MCP Server?

The Remote Authless Model Context Protocol (MCP) Server on Cloudflare is a powerful tool designed to facilitate seamless integration of various AI applications with external data sources and tools through the Model Context Protocol. This server serves as a bridge, enabling applications like Claude Desktop, Continue, Cursor, and others to interact with different tools and models without requiring authentication processes, making it ideal for deployment in environments where simplicity and speed are paramount.

🔧 Core Features & MCP Capabilities

The Remote Authless MCP Server offers several key features that make it indispensable for AI developers and users. It is built using the Cloudflare Worker platform, ensuring reliable performance and easy deployment. The server's primary role is to expose tools and models via the Model Context Protocol (MCP), allowing them to be seamlessly integrated into various applications.

1. Tool Integration

To tailor your MCP Server with specific tools, you can define each tool inside the init() method of src/index.ts using this.server.tool(...). This method allows for dynamic and customizable configurations, making it easy to adapt the server to meet the diverse needs of different applications.

2. Deployment Options

Users have two primary deployment options:

• Auto-deployment via GitHub

  • Use the provided Deploy to Workers button to deploy your MCP server directly on Cloudflare.
  • After deployment, you will get a URL like remote-mcp-server-authless.<your-account>.workers.dev/sse.

• Manual Deployment

  • Alternatively, users can manually deploy the MCP Server on their local machine using the following command:

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

3. Compatibility with AI Clients

The Remote Authless MCP Server is fully compatible with popular AI clients, including Claude Desktop and Continue. While support for other tools like Cursor is limited to tool functionality, making full integration challenging.

3. Customizing Your MCP Server

   • To add custom tools, define them in the init() method of src/index.ts using this.server.tool(...).

4. Connecting to Cloudflare AI Playground

   • Follow these steps to connect your MCP server from the Cloudflare AI Playground:
     1. Visit https://playground.ai.cloudflare.com/
     2. Enter the URL of your deployed MCP server (remote-mcp-server-authless.<your-account>.workers.dev/sse)
     3. Start using your custom tools directly from the playground.

5. Connecting Claude Desktop to Your MCP Server

   • Use the mcp-remote proxy to connect to your server:

     {
       "mcpServers": {
         "calculator": {
           "command": "npx",
           "args": [
             "mcp-remote",
             "http://localhost:8787/sse" // or remote-mcp-server-authless.<your-account>.workers.dev/sse
           ]
         }
       }
     }
     

6. Restarting Claude

   • After updating the configuration, restart Claude to see your tools become available.
