mcp-utm

MCP server for managing UTM virtual machines on macOS via AppleScript.

Provides 22 tools for cloning, configuring, and controlling UTM VMs — including proper MAC address randomization for Apple Virtualization Framework clones, which enables concurrent VMs with unique network identities.

Install

# PyPI
uvx mcp-utm

# Or install globally
uv tool install mcp-utm
pip install mcp-utm

How MAC randomization works

Apple's Virtualization Framework ignores MacAddress changes written directly to config.plist — UTM caches the config in memory. This server uses AppleScript's update configuration command which properly updates UTM's internal state, giving each clone a unique MAC and therefore a unique IP on the 192.168.64.0/24 subnet.
