📦 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)

  1. Clone and set up environment:

    # Clone repository
cd ~/Documents/Cline/MCP  # For Cline users
# OR
cd your/preferred/directory  # For manual installation

git clone https://github.com/canvrno/ProxmoxMCP.git
cd ProxmoxMCP

# 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 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

    You should see either:

    • A successful connection to your Proxmox server
    • Or a connection error (if Proxmox details are incorrect)

⚙️ 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

🚀 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

Cline Desktop Integration

For Cline users, add this configuration to your MCP settings file (typically at ~/.config/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json):

{
    "mcpServers": {
        "github.com/canvrno/ProxmoxMCP": {
            "command": "/absolute/path/to/ProxmoxMCP/.venv/bin/python",
            "args": ["-m", "proxmox_mcp.server"],
            "cwd": "/absolute/path/to/ProxmoxMCP",
            "env": {
                "PYTHONPATH": "/absolute/path/to/ProxmoxMCP/src",
                "PROXMOX_MCP_CONFIG": "/absolute/path/to/ProxmoxMCP/proxmox-config/config.json",
                "PROXMOX_HOST": "your-proxmox-host",
                "PROXMOX_USER": "username@pve",
                "PROXMOX_TOKEN_NAME": "token-name",
                "PROXMOX_TOKEN_VALUE": "token-value",
                "PROXMOX_PORT": "8006",
                "PROXMOX_VERIFY_SSL": "false",
                "PROXMOX_SERVICE": "PVE",
                "LOG_LEVEL": "DEBUG"
            },
            "disabled": false,
            "autoApprove": []
        }
    }
}

To help generate the correct paths, you can use this command:

# This will print the MCP settings with your absolute paths filled in
python -c "import os; print(f'''{{
    \"mcpServers\": {{
        \"github.com/canvrno/ProxmoxMCP\": {{
            \"command\": \"{os.path.abspath('.venv/bin/python')}\",
            \"args\": [\"-m\", \"proxmox_mcp.server\"],
            \"cwd\": \"{os.getcwd()}\",
            \"env\": {{
                \"PYTHONPATH\": \"{os.path.abspath('src')}\",
                \"PROXMOX_MCP_CONFIG\": \"{os.path.abspath('proxmox-config/config.json')}\",
                ...
            }}
        }}
    }}
}}''')"

Important:

  • All paths must be absolute
  • The Python interpreter must be from your virtual environment
  • The PYTHONPATH must point to the src directory
  • Restart VSCode after updating MCP settings
