mcpbundles-proxy 0.1.1

Desktop proxy for MCPBundles - tunnels cloud requests to local services

MCPBundles Desktop Proxy

Tunnel cloud requests from MCPBundles.com to local services on your machine.

Connect your local databases, APIs, and services to the MCPBundles platform without exposing them to the internet. The proxy runs in the background and securely forwards requests over an encrypted WebSocket tunnel.

Features

• Secure OAuth2 authentication
• Auto-reconnection with exponential backoff
• Encrypted token storage
• Dynamic port forwarding to any localhost service
• Local browser service (optional) - Control a real browser on your machine from the cloud
• Background daemon with status monitoring
• Comprehensive logging
• Fast and lightweight (~5MB)

Installation

Basic Installation

pip install mcpbundles-proxy

With Browser Service

pip install mcpbundles-proxy[browser]

# After installation, install Playwright browsers
playwright install chromium

Full Installation (All Features)

pip install mcpbundles-proxy[all]
playwright install chromium

Quick Start

1. Authenticate

mcpbundles-proxy login

This opens your browser to authenticate with MCPBundles.com. Once complete, you can close the browser.

2. Start the tunnel

mcpbundles-proxy start

The tunnel runs in the background. You can close your terminal - it keeps running.

3. Check status

mcpbundles-proxy status

Example output:

✅ Running (PID: 12345)
   Uptime: 2:30:15
   Tunnel: 🟢 connected

Commands

Command	Description
login	Authenticate with MCPBundles
start	Start tunnel daemon in background
stop	Stop tunnel daemon
restart	Restart tunnel daemon
status	Show connection status
logs	View tunnel logs
logs -f	Follow logs in real-time
logout	Remove stored credentials

How It Works

1. You create a provider on MCPBundles.com with base URL like localhost:5432
2. When you run a tool from that provider, the request is sent through the tunnel
3. The desktop proxy receives it and forwards to your local service
4. The response flows back through the tunnel to the cloud

Local Browser Service

The proxy can run a local browser (Chromium) that cloud tools can control. Perfect for web scraping, testing, and automation.

Enable from web:

1. Go to MCPBundles.com → Settings
2. Toggle "Browser Service" on
3. Choose "Show browser window" or "Hidden mode"
4. Browser starts automatically on your machine

Benefits:

• 🖥️ Visible mode: Watch the browser in action on your screen
• 🕶️ Hidden mode: Run in background for pure automation
• 🌍 Use your IP: Browse from your location
• 🔒 Secure: Browser runs locally, controlled via tunnel
• 📸 Full control: Screenshots, PDFs, form filling, JavaScript execution

Cloud tools can:

• Scrape websites using your IP/location
• Test web apps on your machine
• Fill forms and submit data
• Take screenshots and PDFs
• Execute JavaScript

All controlled from MCPBundles.com web interface!

Configuration

All configuration is stored in ~/.mcpbundles/:

• token.json - Encrypted OAuth tokens
• tunnel.pid - Process ID of running daemon
• tunnel.log - Log file

Security

• ✅ Only forwards to localhost - never to your network
• ✅ OAuth2 authenticated tunnel
• ✅ All traffic encrypted over WSS (WebSocket Secure)
• ✅ Tokens stored encrypted with machine-specific key
• ✅ File permissions set to user-only (0600)

Requirements

• Python 3.8+
• macOS or Linux (Windows support coming soon)

Troubleshooting

Tunnel won't start

# Check if already running
mcpbundles-proxy status

# View logs for errors
mcpbundles-proxy logs

# Try re-authenticating
mcpbundles-proxy logout
mcpbundles-proxy login
mcpbundles-proxy start

Can't connect to local service

Make sure your local service is running:

# Example: Check if PostgreSQL is running on port 5432
curl http://localhost:5432
# or
lsof -i :5432

The proxy only forwards to services that are already running locally.
