Deploy a remote MCP server on Cloudflare Workers without authentication for AI tools and client integration
The Remote Authentication-Less Model Context Protocol (MCP) Server allows you to deploy a MCP server without requiring authentication, specifically for use with Cloudflare Workers. This setup enables seamless integration of AI applications like Claude Desktop, Continue, Cursor, and others by providing them access to specific data sources and tools through the MCP protocol. Unlike traditional authenticated servers, this server operates openly, making it suitable for quick prototyping and testing environments.
This server provides a simple yet powerful way to expose your tools as part of AI workflows. You can define various tools within the src/index.ts
file using the this.server.tool()
method in the init()
function. This customization allows you to tailor the server's functionality to fit specific needs, making it highly adaptable for different applications.
The Remote Authentication-Less MCP Server leverages Cloudflare Workers for efficient and scalable deployment. It adheres to the Model Context Protocol (MCP) which defines a standardized communication method between AI clients and the server, ensuring compatibility across different applications. The protocol flow diagram below illustrates how data flows from an AI application through a client, then to our server, eventually reaching the required tools.

This diagram shows the interaction flow where AI applications act as clients that send prompts and receive responses through MCP servers, which then interact with corresponding tools to provide answers or perform tasks.
To quickly get your Remote Authentication-Less MCP Server up and running, you can use a pre-built template provided via Cloudflare:
npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless
Alternatively, for a more interactive deployment experience, visit this URL to deploy directly on Cloudflare Workers:
Once deployed, your MCP server will be accessible through a unique URL like remote-mcp-server-authless.<your-account>.workers.dev/sse
.
This server is particularly useful for developers looking to rapidly develop and deploy AI solutions while integrating various tools. Here are two realistic scenarios where this functionality shines:
Financial Analysis Tool Integration: By leveraging the Remote Authentication-Less MCP Server, you can integrate financial analysis tools with AI applications like Claude Desktop or Continue. This setup allows users to input specific financial data prompts into an AI interface and receive analyzed results directly without needing manual tool switching.
Medical Diagnosis Workflow: The server enables seamless integration of various medical diagnostic tools, making it easier for healthcare providers to run tests and receive diagnoses via AI workflows. The MCP protocol facilitates real-time communication between the client application and the server, ensuring fast and accurate data processing.
The Remote Authentication-Less MCP Server is designed to work seamlessly with popular AI clients like Claude Desktop, Continue, and Cursor. The compatibility matrix below outlines which clients fully support this server:
MCP Client | Resources | Tools | Prompts |
---|---|---|---|
Claude Desktop | ✅ | ✅ | ✅ |
Continue | ✅ | ✅ | ✅ |
Cursor | ❌ | ✅ | ❌ |
While the server is optimized for performance, it also ensures compatibility across a variety of MCP clients. The following section includes a configuration code sample that demonstrates how to set up your MCP server.
{
"mcpServers": {
"[server-name]": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-[name]"],
"env": {
"API_KEY": "your-api-key"
}
}
}
}
For advanced configurations and security settings, you can modify the environment variables within your package.json
. This includes setting up API keys, configuring data sources, or adjusting other server parameters to meet specific needs.
A: Yes, as long as it is an MCP client, such as Claude Desktop, Continue, and Cursor, you can connect to the Remote Authentication-Less MCP Server. However, note that not all clients support full features.
A: You can add your own tools by defining them in the src/index.ts
file using the this.server.tool()
method within the init()
function.
A: Security is managed through environment variables and configuration files. While no explicit authentication is required, it's recommended to use strong API keys to prevent unauthorized access.
A: Yes, but deploying it directly on a worker service can provide the benefits of lower latency and higher scalability.
A: Common issues include incorrect API keys or misconfigured environment variables. Check these settings first; detailed error logs will help diagnose more complex problems.
