MCP Proxmox Server

Installation

Add the following to your MCP client configuration file.

Configuration

{
  "mcpServers": {
    "bsahane-mcp-proxmox": {
      "command": "python",
      "args": [
        "-m",
        "proxmox_mcp.server"
      ],
      "env": {
        "PROXMOX_VERIFY": "true",
        "PROXMOX_API_URL": "https://proxmox.example.com:8006",
        "PROXMOX_TOKEN_ID": "root@pam!mcp-proxmox",
        "PROXMOX_DEFAULT_NODE": "pve",
        "PROXMOX_TOKEN_SECRET": "<secret>",
        "PROXMOX_DEFAULT_BRIDGE": "vmbr0",
        "PROXMOX_DEFAULT_STORAGE": "local-lvm"
      }
    }
  }
}

You set up and run an MCP server to expose Proxmox utilities for discovery, lifecycle management, networking, snapshots, metrics, and orchestration. With a local stdio-based server you can start it from Python or via a console script, then control Proxmox resources through MCP-compatible clients.

How to use

You interact with the MCP Proxmox server by starting a local, stdio-based MCP server and connecting your MCP client (Cursor, Claude, or another MCP client) to it. Use the available MCP tools to discover Proxmox resources, manage VMs/LXCs, handle images, templates, backups, and perform orchestration tasks. The server prints protocol data to stdout and logs to stderr, and it reads its configuration from environment variables or an .env file.

How to install

# Prerequisites
- Python 3.8+
- Virtual environment support

# Clone the project
git clone https://github.com/bsahane/mcp-proxmox.git
cd mcp-proxmox

# Create and activate a virtual environment
python3 -m venv .venv
source .venv/bin/activate

# Upgrade pip and install dependencies
python -m pip install -U pip
pip install -r requirements.txt

# (Optional) install the package locally in editable mode
pip install -e .

Configure environment and run

cp .env.example .env
```

Then edit the .env values to point to your Proxmox instance and credentials. Example keys you will set:

```
PROXMOX_API_URL="https://proxmox.example.com:8006"
PROXMOX_TOKEN_ID="root@pam!mcp-proxmox"
PROXMOX_TOKEN_SECRET="<secret>"
PROXMOX_VERIFY="true"
PROXMOX_DEFAULT_NODE="pve"
PROXMOX_DEFAULT_STORAGE="local-lvm"
PROXMOX_DEFAULT_BRIDGE="vmbr0"
```

Notes:
- Use an API token with appropriate ACLs; discovery can use a broad role, while lifecycle operations should use a more restricted role on a pool.
- Using .env avoids shell history issues with special characters like ! in tokens.
```
```

Run the server in stdio mode via Python or the installed console script:

```
# Option 1: Python module form
source .venv/bin/activate
python -m proxmox_mcp.server
```

```
# Option 2: Installed console script
source .venv/bin/activate
proxmox-mcp

Configure in MCP clients

# Cursor portable example
{
  "mcpServers": {
    "proxmox-mcp": {
      "command": "python",
      "args": ["-m", "proxmox_mcp.server"]
    }
  }
}
```

```
# Claude for Desktop portable example
{
  "mcpServers": {
    "proxmox-mcp": {
      "command": "python",
      "args": ["-m", "proxmox_mcp.server"]
    }
  }
}

Notes on usage and configuration

- The server uses a stdio transport and prints MCP protocol data to stdout while logs go to stderr. Authentication is driven by your environment variables and/or the .env file.

Security and maintenance

- Keep API tokens and credentials restricted with least privilege. Regularly rotate tokens and keep your .env file secure. Monitor logs for unusual activity and ensure network access to Proxmox is restricted to trusted clients.

Troubleshooting

- If the server fails to start, verify that your Python environment is active and that the required packages are installed. Check for missing dependencies in the log on startup. Ensure the Proxmox API URL, token, and verify flag are correct in the .env file.
