VMware Fusion MCP Server

A Model Context Protocol (MCP) server for managing VMware Fusion virtual machines via the Fusion REST API, built with FastMCP.

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

1. Clone the repository:

   git clone https://github.com/yeahdongcn/vmware-fusion-mcp-server.git cd vmware-fusion-mcp-server

2. Set up the environment and install dependencies:

   make env

VMware Fusion Setup

1. Enable the REST API:

   • Open VMware Fusion > Preferences > Advanced

   • Check "Enable REST API"

   • Note the API port (default: 8697)

2. Start the REST API service:

   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

• Set VMREST_USER and VMREST_PASS to your vmrest credentials.

Usage

Run the MCP Server

With Make

With uvx (recommended for VS Code/LLM)

VS Code / LLM Integration

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

1. Install

   uv pip install uvx

2. Add to your MCP server config (e.g.,

   { "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.
