Cloudflare Integration for MCPhub

This PR adds Cloudflare integration to MCPhub, allowing you to expose your MCPhub instance through Cloudflare with SSL/TLS encryption and custom domain support.

Features

• Cloudflare Worker: Proxy requests to MCPhub with proper handling of SSE connections
• Cloudflare Tunnel: Securely expose local MCPhub instances through Cloudflare's network
• Client Configuration Generator: Generate client configuration for different deployment scenarios
• Comprehensive Documentation: Detailed guides for setting up Cloudflare integration

Implementation Details

Cloudflare Worker

The Cloudflare Worker (cloudflare-worker/src/index.js) proxies requests to the MCPhub SSE endpoint, handling:

• CORS headers
• Authentication
• Streaming connections
• Error handling

Cloudflare Tunnel Setup

The setup script (scripts/setup-cloudflare-tunnel.sh) automates the process of:

• Installing cloudflared
• Authenticating with Cloudflare
• Creating a tunnel
• Configuring DNS routing
• Starting the tunnel
• Generating client configuration

Client Configuration Generator

The generator script (scripts/generate-client-config.js) creates client configuration for:

• Local deployment
• Cloudflare deployment
• With or without API key authentication

Documentation

Comprehensive documentation (docs/CLOUDFLARE_DEPLOYMENT.md) covers:

• Cloudflare Tunnel setup
• Cloudflare Worker deployment
• Client configuration
• Troubleshooting

Usage

1. Setup Cloudflare Tunnel:

   chmod +x scripts/setup-cloudflare-tunnel.sh
   DOMAIN="pixeliumperfecto.co.uk" ./scripts/setup-cloudflare-tunnel.sh

2. Generate Client Configuration:

   node scripts/generate-client-config.js --deployment cloudflare --domain pixeliumperfecto.co.uk

3. Use the Generated Configuration:

   {
     "mcpServers": {
       "MCPhub": {
         "type": "sse",
         "url": "https://pixeliumperfecto.co.uk/sse",
         "keepAliveInterval": 60000,
         "owner": "admin"
       }
     }
   }

Testing

• Tested the backend server on port 3001
• Verified the SSE endpoint is working
• Generated and validated client configurations for both local and Cloudflare deployments

This PR addresses the requirement to expose MCPhub through Cloudflare at pixeliumperfecto.co.uk:3000/sse.

Description by Korbit AI

What change is being made?

Add a Cloudflare integration for MCPhub by introducing a Cloudflare Worker and a setup for Cloudflare Tunnel, allowing secure access and management of an MCPhub instance through both local and public deployments.

Why are these changes being made?

The changes are made to enhance the accessibility and security of MCPhub by leveraging Cloudflare's network capabilities, including secure SSL/TLS connections, custom domain support, and Server-Sent Events (SSE) management. The integration efforts aim to provide a robust and scalable way to deploy MCPhub for local and public access, solving potential issues of direct server exposure and enhancing user management approach.

Cloudflare Worker Integration Update

I've updated the PR with the following changes:

1. Configured for Your Cloudflare Account:

   • Updated wrangler.toml with your account ID: 2b2a1d3effa7f7fe4fe2a8c4e48681e3
   • Set worker name to: mcp
   • Configured worker URL: https://mcp.pixeliumperfecto.workers.dev

2. Added Deployment Script:

   • Created scripts/deploy-cloudflare-worker.sh for easy deployment
   • Script handles authentication, configuration, and deployment
   • Generates client configuration automatically

3. Enhanced Client Configuration:

   • Updated generator to support API keys
   • Added specific worker deployment option
   • Generated configuration for your worker URL

4. Security Improvements:

   • Removed hardcoded credentials
   • Using environment variables for sensitive information
   • Added validation for required environment variables

Deployment Instructions

1. Set Environment Variables:

   export CLOUDFLARE_API_KEY="eae82cf159577a8838cc83612104c09c5a0d6"
   export CLOUDFLARE_ACCOUNT_ID="2b2a1d3effa7f7fe4fe2a8c4e48681e3"

2. Run Deployment Script:

   chmod +x scripts/deploy-cloudflare-worker.sh
   ./scripts/deploy-cloudflare-worker.sh

3. Use Generated Configuration:

   • The script generates mcphub-worker-config.json with your worker URL
   • This configuration can be used directly with MCP clients

The worker will proxy requests to your MCPhub instance running on port 3001, making it accessible at https://mcp.pixeliumperfecto.workers.dev/sse.
