   # 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

Running the Server

Development Mode

For testing and development:

MCP Transport Configuration

The MCP server supports multiple transport modes. Configure these in the mcp section of your proxmox-config/config.json:

• STDIO: Default. Run over stdio for MCP clients like Claude Desktop/Cline.

• SSE: Serve MCP over Server-Sent Events (SSE).

• STREAMABLE: Serve MCP over streamable HTTP.

Open WebUI Integration

Configure Open WebUI

1. Access your Open WebUI instance

2. Navigate to Settings → Connections → OpenAPI

3. Add new API configuration:

Natural Language VM Creation

The system supports natural language VM creation requests through AI assistants. Example requests:

• "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

• Note: No cloud-init image support

File-based Storage (local, NFS, CIFS)

• Format: qcow2

• Cloud-init support

• Flexible snapshot capabilities

Production Readiness

ProxmoxMCP Plus is ready for production deployment. The system supports natural language VM creation requests through AI assistants. When a user requests VM creation (e.g., "create a VM with 1 cpu core and 2 GB ram with 10GB of storage disk"), the system will:

1. Call the create_vm API endpoint

2. Automatically select appropriate storage and format

3. Create VMs matching the specified requirements

4. Return detailed configuration information

5. Provide next-step recommendations

Development

After activating your virtual environment:

• Run tests: pytest

• Format code: black .

• Type checking: mypy .

• Lint: ruff .
