Proxmox MCP Server

A Model Context Protocol (MCP) server for managing Proxmox VE infrastructure through AI assistants. Available as an npm package, Docker container, or standalone Python application.

Project Background

In May 2025, we launched the original ProxmoxMCP server with FastMCP, FastAPI, and virtual environments. Based on community feedback and operational experience, we rebuilt the project as ProxmoxEmCP - a cleaner, simpler implementation that eliminates setup complexity while maintaining full functionality. This version uses the official MCP SDK directly and runs without virtual environment dependencies, making deployment and maintenance significantly easier.

Quick Start

npm/npx

# Install globally
npm install -g @puregrain/proxmox-emcp-node

# Or run directly with npx
npx @puregrain/proxmox-emcp-node

Docker Hub

docker run -d \
  --name proxmox-emcp \
  -e PROXMOX_HOST="192.168.1.100" \
  -e PROXMOX_TOKEN_ID="your-token-id" \
  -e PROXMOX_TOKEN_SECRET="your-token-secret" \
  puregrain/proxmox-emcp:latest

Prerequisites

• Proxmox VE: Version 7.0 or higher with API access enabled

• For npm package: Node.js 18+

• For Docker: Docker Engine installed

• For local Python: Python 3.9+

• API Token: Created in Proxmox with appropriate permissions

Installation Methods

npm Package

The npm package provides a native Node.js implementation without Docker requirements.

# Install globally
npm install -g @puregrain/proxmox-emcp-node

# Set environment variables
export PROXMOX_HOST="192.168.1.100"
export PROXMOX_TOKEN_ID="your-token-id"
export PROXMOX_TOKEN_SECRET="your-token-secret"

# Run the server
proxmox-emcp-node

Using with npx (no installation required):

PROXMOX_HOST=192.168.1.100 \
PROXMOX_TOKEN_ID=your-token-id \
PROXMOX_TOKEN_SECRET=your-token-secret \
npx @puregrain/proxmox-emcp-node

Docker Container

Using Docker Compose (Recommended)

1. Clone the repository:

git clone https://github.com/PureGrain/ProxmoxEmCP.git
cd ProxmoxEmCP

2. Configure environment:

cp .env.example .env
# Edit .env with your Proxmox credentials

3. Start the container:

docker-compose up -d

Using Docker CLI

  puregrain/proxmox-emcp:latest

Using GitHub Container Registry

docker run -d \
  --name proxmox-emcp \
  -e PROXMOX_HOST="192.168.1.100" \
  -e PROXMOX_TOKEN_ID="your-token-id" \
  -e PROXMOX_TOKEN_SECRET="your-token-secret" \
  ghcr.io/puregrain/proxmox-emcp:latest

Local Python

# Clone the repository
git clone https://github.com/PureGrain/ProxmoxEmCP.git
cd ProxmoxEmCP

# Install dependencies
pip install -r requirements.txt

# Set environment variables
export PROXMOX_HOST="192.168.1.100"
export PROXMOX_TOKEN_ID="your-token-id"
export PROXMOX_TOKEN_SECRET="your-token-secret"

# Run the server
python mcp_server_stdio.py

Open WebUI Integration

For Open WebUI users, we provide ProxmoxWeaver - a specialized tool that brings full Proxmox management capabilities directly into your Open WebUI interface.

ProxmoxWeaver is a native Open WebUI tool that provides the same comprehensive Proxmox VE management features as our MCP server, but specifically designed for the Open WebUI ecosystem.

Features:

• Direct integration with Open WebUI's tool system

• Same powerful Proxmox management capabilities

• No additional containers or services required

• Simple installation through Open WebUI's tool marketplace

Installation:

1. Visit the ProxmoxWeaver repository

2. Copy the tool configuration

3. In Open WebUI, navigate to Tools → Add Tool

4. Paste the ProxmoxWeaver configuration

5. Configure your Proxmox credentials in the tool settings

Usage:

Once installed, ProxmoxWeaver appears as a native tool in Open WebUI, allowing you to:

• Query and manage VMs and containers

• Monitor cluster health and resources

• Execute commands and create snapshots

• Manage storage, backups, and templates

• All through natural language interactions in Open WebUI

This integration is perfect for teams already using Open WebUI who want to add Proxmox management capabilities without additional infrastructure.

Configuration

Environment Variables

Creating API Token

1. Log into Proxmox Web UI

2. Navigate to Datacenter → Permissions → API Tokens

3. Click Add to create a new token

4. Configure the token:

   • User: Select your user (e.g., root@pam)

   • Token ID: Choose a descriptive name

   • Privilege Separation: Uncheck for full user permissions

5. Copy the token secret (shown only once!)

AI Agent Integration

Configure your AI assistant (Claude Desktop, Cline, or any MCP-compatible client) to connect to the server.

Troubleshooting

Connection Issues

• Verify Proxmox is reachable: ping <PROXMOX_HOST>

• Check API port: Ensure port 8006 is accessible

• SSL certificates: Set PROXMOX_VERIFY_SSL=false for self-signed certs

Authentication Failures

• Token permissions: Ensure token has required permissions

• Token format: Verify TOKEN_ID and TOKEN_SECRET are correct

• User privileges: Check user has appropriate Proxmox permissions

Viewing Logs

# Docker logs
docker logs proxmox-emcp

# npm/Node.js - set LOG_LEVEL
LOG_LEVEL=DEBUG npx @puregrain/proxmox-emcp-node

Common Issues

• "Connection refused": Check firewall and Proxmox API service

• "Unauthorized": Verify token credentials

• "SSL verification failed": Set PROXMOX_VERIFY_SSL=false
