• Python 3.9 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)

1. Clone and set up environment:

   # Clone repository git clone https://github.com/RekklesNA/ProxmoxMCP-Plus.git cd ProxmoxMCP-Plus # Create and activate virtual environment uv venv source .venv/bin/activate # Linux/macOS # OR .\.venv\Scripts\Activate.ps1 # Windows

2. Install dependencies:

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

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 "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

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

3. Add new API configuration:

Natural Language VM Creation

Users can now request VMs using natural language:

• "Can you create a VM with 1 cpu core and 2 GB ram with 10GB of storage disk"

• "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
