VMware Fusion MCP Server

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 uvx:
   uv pip install uvx
2. Add to your MCP server config (e.g., .vscode/mcp.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.
