Remote Authless MCP Server on Cloudflare

This example provides instructions for deploying a remote MongoDB-based MCP (Model Context Protocol) server without requiring authentication, specifically on Cloudflare Workers.

Overview: What is a Remote Authless MCP Server?

An MCP Server is a critical component that enables AI applications like Claude Desktop, Continue, and Cursor to communicate with various data sources and tools using the Model Context Protocol. This remote server operates authlessly, meaning it does not require user authentication for requests. It can be deployed on Cloudflare Workers to provide seamless integration with these AI applications.

🔧 Core Features & MCP Capabilities

This Remote Authless MCP Server offers robust features built around the Model Context Protocol, facilitating an intuitive and secure connection between AI applications and external tools or services. The server architecture ensures compatibility across multiple platforms while maintaining high performance and reliability.

Real-time Data Exchange via SSE (Server-Sent Events)

The server utilizes the SSE protocol for real-time data exchange, allowing AI applications to receive updates from live streams of data in near real-time. This feature is essential for use cases where immediate feedback or dynamic adjustments are needed based on changing data conditions.

Custom Tool Integration

Users can add their own custom tools directly into the MCP server by defining them within the init() method of src/index.ts using this.server.tool(...). This flexibility enables developers to tailor the server's functionality to meet specific project requirements, enhancing its utility in various AI workflows.

⚙️ MCP Architecture & Protocol Implementation

The architecture of this Remote Authless MCP Server is designed with scalability and efficiency in mind. It leverages Cloudflare Workers for hosting, ensuring low-latency and high-availability, while employing the Model Context Protocol to establish a robust communication layer between the server and various AI applications.

This diagram demonstrates the data architecture, where external Data Sources are connected to the MCP Server through a Cloudflare Worker environment. The MCP Server then forwards the processed data or commands to AI Applications, allowing them to perform necessary operations.

🚀 Getting Started with Installation

To deploy your Remote Authless MCP Server on Cloudflare Workers quickly and easily:

1. Deploy Directly with Button:

2. Manual Deployment via Command Line:

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

This setup ensures that you can deploy your Server with just a single click or by running the provided command, making it accessible at a URL like remote-mcp-server-authless.<your-account>.workers.dev/sse.

💡 Key Use Cases in AI Workflows

Here are two real-world AI workflow use cases emphasizing how this Remote Authless MCP Server can be employed:

Use Case 1: Real-Time Financial Analysis

Utilize the server to process financial data and provide real-time analysis. For instance, a bank could send live stock prices or market data from an external API to the MCP Server. The server would then forward these updates to AI applications for immediate processing and presentation.

Use Case 2: Natural Language Processing for Customer Support

Implement custom tools within the server that handle natural language processing tasks such as sentiment analysis or keyword extraction. This can be integrated with customer support platforms, allowing them to quickly assess the emotions of customer queries through real-time stream inputs.

🔌 Integration with MCP Clients

This Remote Authless MCP Server is compatible with several MCP clients:

MCP Client	Resources	Tools	Prompts	Status
Claude Desktop	✅	✅	✅	Full Support
Continue	✅	✅	✅	Full Support
Cursor	❌	✅	❌	Tools Only

MCP Configuration Sample

To set up your configuration, use the following JSON snippet in your MCP client's settings:

{
  "mcpServers": {
    "[server-name]": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-[name]"],
      "env": {
        "API_KEY": "your-api-key"
      }
    }
  }
}

Replace [server-name] and @modelcontextprotocol/server-[name] with your specific server name and package details.
