Features

List VMs: View all VMs registered in VMware Fusion.
Get VM Info: Retrieve detailed information about a specific VM.
Power Operations: Perform power actions (on, off, suspend, pause, unpause, reset) on a VM.
Get Power State: Query the current power state of a VM.
Modern MCP/LLM Integration: Exposes all features as MCP tools for LLMs and agent frameworks.

Prerequisites

VMware Fusion Pro (with REST API enabled)
Python 3.10+
uv (recommended) or pip
uvx (for VS Code/LLM integration)

Installation

Clone the repository: bash git clone https://github.com/yeahdongcn/vmware-fusion-mcp-server.git cd vmware-fusion-mcp-server
Set up the environment and install dependencies: bash make env

VMware Fusion Setup

Enable the REST API:
Open VMware Fusion > Preferences > Advanced
Check "Enable REST API"
Note the API port (default: 8697)
Start the REST API service: bash vmrest The API will be available at http://localhost:8697 by default.

Configuration

The server connects to VMware Fusion's REST API at http://localhost:8697 by default. You must configure authentication for the vmrest API using environment variables:

VMREST_USER: Username for the vmrest API (required if authentication is enabled)
VMREST_PASS: Password for the vmrest API (required if authentication is enabled)

These must be set in your shell, in your VS Code MCP config, or in your deployment environment.

Example: MCP server config for VS Code with credentials

{
  "mcpServers": {
    "vmware-fusion": {
      "command": "uvx",
      "args": ["vmware-fusion-mcp-server"],
      "env": {
        "VMREST_USER": "your-username",
        "VMREST_PASS": "your-password"
      }
    }
  }
}

Set VMREST_USER and VMREST_PASS to your vmrest credentials.

Usage

Run the MCP Server

With Make

VMREST_USER=your-username VMREST_PASS=your-password make run

With uvx (recommended for VS Code/LLM)

VMREST_USER=your-username VMREST_PASS=your-password uvx vmware-fusion-mcp-server

VS Code / LLM Integration

To use this server as a tool provider in VS Code (or any MCP-compatible client):

Install uvx: bash uv pip install uvx
Add to your MCP server config (e.g., .vscode/mcp.json): json { "mcpServers": { "vmware-fusion": { "command": "uvx", "args": ["vmware-fusion-mcp-server"], "env": { "VMREST_USER": "your-username", "VMREST_PASS": "your-password" } } } }
Set VMREST_USER and VMREST_PASS to your vmrest credentials.
You can now use the VMware Fusion tools in any MCP-enabled LLM or agent in VS Code.
