proxmoxer-mcp-server 0.1.0

Proxmox VE MCP Server - Manages Proxmox infrastructure via MCP protocol

Proxmox MCP Server

I tried a few other MCP servers for my homelab Proxmox setup, and couldn't get one that did exactly what I was after.

It defaults to stdio output. It uses FastMCP, so you can switch to http or sse as needed. Uses proxmoxer to connect to Proxmox and handle commands.

AI DISCLAIMER - I used OpenCode to assist with this. This means AI-generated code is present. Audit the source and verify for yourself before you use in production.

Requirements

• Python 3.10+
• Proxmox VE
• a Proxmox API token with the following permissions (you can omit things you want to deny): VM.Console, VM.Config.Memory, Datastore.Audit, VM.Audit, VM.Snapshot.Rollback, Datastore.AllocateSpace, Sys.Audit, SDN.Audit, VM.Config.Disk, VM.Config.Network, VM.Config.CPU, Sys.Console, VM.Config.Cloudinit, Datastore.Allocate, Pool.Audit, VM.Config.CDROM, VM.PowerMgmt, Pool.Allocate, SDN.Use, VM.Clone, VM.Snapshot, VM.Config.Options, VM.Allocate

Install

Option 1: Install from PyPI (Recommended)

pip install proxmoxer-mcp-server
proxmoxer-mcp-server  # Runs with environment variables

Option 2: Install from Source

git clone https://git.airstrikeivanov.com/airstrikeivanov/proxmoxer-mcp-server.git && cd proxmoxer-mcp-server
python -m venv venv && source venv/bin/activate  # Virtualenv strongly recommended
pip install -e .  # Editable install

Option 3: Development Install

git clone https://git.airstrikeivanov.com/airstrikeivanov/proxmoxer-mcp-server.git && cd proxmoxer-mcp-server
python -m venv venv && source venv/bin/activate
pip install -e ".[dev]"  # Includes dev dependencies

Configuration

Copy .env.example to .env and edit, or set environment variables elsewhere.

Running

# After PyPI install
proxmoxer-mcp-server

# After source install
python -m proxmoxer_mcp_server
# or
proxmoxer-mcp-server

Configuration

The MCP server requires a handful of variables to start up. I don't provide defaults yet.

Required Environment Variables

Variable	Description
PROXMOX_HOST	Proxmox server URL (without protocol prefix)
PROXMOX_TOKEN_ID	API token identifier in format: user@realm!tokenid
PROXMOX_TOKEN_SECRET	API token secret
PROXMOX_NODE	Default Proxmox node name

Optional Environment Variables

Variable	Description
PROXMOX_SKIP_TLS_VERIFY	Skip TLS verification (true for development, false for production)
PROXMOX_ALLOW_DESTRUCTIVE	Enable/disable destructive operations (default: false)
PROXMOX_CONFIRMATION_MODE	Confirmation strictness: strict or relaxed (default: strict)
PROXMOX_AUDIT_LEVEL	Audit detail: minimal, standard, or full (default: standard)
LOG_LEVEL	Log level (DEBUG, INFO, WARNING, ERROR)

FastMCP Transport Operations

Variable	Description
MCP_HOST	Host address to bind to (default: 127.0.0.1) - must be set to enable remote connections
MCP_PORT	Port to listen on (default: 8080)
MCP_TRANSPORT	Transport type to use (default: "stdio") - options: "stdio", "http", "sse"

Destructive Operations (Two-Step Process)

# Step 1: Request operation (requires confirmation)
delete_vm(node="pve", vmid="100", confirmed=False)
# Returns: "CONFIRMATION REQUIRED"

# Step 2: Execute with confirmation
delete_vm(node="pve", vmid="100", confirmed=True)
# Executes the deletion
