Remote Authless MCP Server on Cloudflare

This document provides detailed technical instructions and comprehensive guidance for setting up an authless Remote MCP Server on Cloudflare Workers, enabling seamless integration with various Model Context Protocol (MCP) clients.

Overview: What is a Remote Authless MCP Server?

A Remote Authless MCP Server allows AI applications to interact with specific tools and data sources through the Model Context Protocol over HTTP. This example demonstrates deploying such a server leveraging Cloudflare Workers without requiring authentication, ensuring ease of use and quick setup for developers.

🔧 Core Features & MCP Capabilities

The core functionality of this Remote Authless MCP Server involves implementing tools as services accessible via an MCP client like Claude Desktop, Continue, or Cursor. By defining this.server.tool(...) within the init() method in src/index.ts, you can integrate diverse tools into your server.

⚙️ MCP Architecture & Protocol Implementation

The architecture of this server is built on Cloudflare Workers, which provides a robust environment for hosting event-driven applications. The MCP protocol ensures seamless communication between the client and server, allowing AI applications to discover and utilize remote servers as if they were local tools.

2. Integration with Cloudflare AI Playground:

   • Easily connect to your remote MCP server from the Cloudflare AI Playground by entering its URL.

🔌 Integration with MCP Clients

The Remote Authless MCP Server is designed to work seamlessly with various MCP clients such as:

• Claude Desktop:
  • Follow the Quickstart instructions at Model Context Protocol documentation.
  • Add server configuration in local settings:

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