Installation

Prerequisites

UV package manager (recommended)
Python 3.10 or higher
Git
Access to a Proxmox server with API token credentials

Before starting, ensure you have:

Proxmox server hostname or IP
Proxmox API token (see API Token Setup)
UV installed (pip install uv)

Option 1: Quick Install (Recommended)

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
.\.venv\Scripts\Activate.ps1  # Windows

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

Create configuration:

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

Edit proxmox-config/config.json:

{
    "proxmox": {
        "host": "PROXMOX_HOST",        # Required: Your Proxmox server address
        "port": 8006,                  # Optional: Default is 8006
        "verify_ssl": false,           # Optional: Set false for self-signed certs
        "service": "PVE"               # Optional: Default is PVE
    },
    "auth": {
        "user": "USER@pve",            # Required: Your Proxmox username
        "token_name": "TOKEN_NAME",    # Required: API token ID
        "token_value": "TOKEN_VALUE"   # Required: API token value
    },
    "logging": {
        "level": "INFO",               # Optional: DEBUG for more detail
        "format": "%(asctime)s - %(name)s - %(levelname)s - %(message)s",
        "file": "proxmox_mcp.log"      # Optional: Log to file
    }
}

Verifying Installation

Check Python environment:

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

Run the tests:
```
pytest
```

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

Log into your Proxmox web interface
Navigate to Datacenter -> Permissions -> API Tokens
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

Running the Server

Development Mode

For testing and development:

# Activate virtual environment first
source .venv/bin/activate  # Linux/macOS
# OR
.\.venv\Scripts\Activate.ps1  # Windows

# Run the server
python -m proxmox_mcp.server

OpenAPI Deployment (Production Ready)

Deploy ProxmoxMCP Plus as standard OpenAPI REST endpoints for integration with Open WebUI and other applications.

Quick OpenAPI Start

# Install mcpo (MCP-to-OpenAPI proxy)
pip install mcpo

# Start OpenAPI service on port 8811
./start_openapi.sh

Docker Deployment

# Build and run with Docker

"Create a new VM for testing with minimal resources"
"I need a development server with 4 cores and 8GB RAM"

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)

✅ Format: qcow2
✅ Cloud-init support
✅ Flexible snapshot capabilities

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

Port already in use

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

Configuration errors

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

Connection issues

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