Option 1: Quick Install (Recommended)

1. Clone and set up environment:

# Clone repository
   git clone https://github.com/agentify-sh/cursor-proxmox-mcp.git
   cd ProxmoxMCP-Plus

   # Create and activate virtual environment
   uv venv

   # or force 3.11 (for mcpo dependency)
   python3.11 -m venv .venv

   # then activate it 
   source .venv/bin/activate  # Linux/macOS
   # OR

2. Install dependencies:

# Install with development dependencies
   uv pip install -e ".[dev]"

   #or via pip
   pip install -e .
   pip install pytest pytest-asyncio black mypy ruff types-requests
   pip install mcpo #need python 3.11

3. Create configuration:

# Create config directory and copy template
   mkdir -p proxmox-config
   cp proxmox-config/config.example.json proxmox-config/config.json

4. Edit proxmox-config/config.json:

{
       "proxmox": {
           "host": "PROXMOX_HOST",        # Required: Your Proxmox server address

       }
   }

Verifying Installation

1. Check Python environment:

python -c "import proxmox_mcp; print('Installation OK')"

2. Run the tests:

pytest

3. Verify configuration:

# Linux/macOS
   PROXMOX_MCP_CONFIG="proxmox-config/config.json" python -m proxmox_mcp.server

   # Windows (PowerShell)
   $env:PROXMOX_MCP_CONFIG="proxmox-config\config.json"; python -m proxmox_mcp.server

Configuration

Proxmox API Token Setup

1. Log into your Proxmox web interface

2. Navigate to Datacenter -> Permissions -> API Tokens

3. Create a new API token:

• Select a user (e.g., root@pam)
• Enter a token ID (e.g., "mcp-token")
• Uncheck "Privilege Separation" if you want full access
• Save and copy both the token ID and secret

The AI assistant will automatically call the appropriate APIs and provide detailed feedback.

Storage Type Support

Intelligent Storage Detection

ProxmoxMCP Plus automatically detects storage types and selects appropriate disk formats:

LVM Storage (local-lvm, vm-storage)

• ✅ Format: raw
• ✅ High performance
• ⚠️ No cloud-init image support

File-based Storage (local, NFS, CIFS)

Production Security

API Key Authentication

Set up secure API access:

export PROXMOX_API_KEY="your-secure-api-key"
export PROXMOX_MCP_CONFIG="/app/proxmox-config/config.json"

Nginx Reverse Proxy

Example nginx configuration:

server {
    listen 80;
    server_name your-domain.com;
    
    location / {
        proxy_pass http://localhost:8811;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

Troubleshooting

Common Issues

1. Port already in use

netstat -tlnp | grep 8811
   # Change port if needed
   mcpo --port 8812 -- ./start_server.sh

2. Configuration errors

# Verify config file
   cat proxmox-config/config.json

3. Connection issues

# Test Proxmox connectivity
   curl -k https://your-proxmox:8006/api2/json/version
