Overview

AI-generated overview

Lets an assistant manage rented Macs on Halfpenny Mac: list machines, check online status, fetch credentials, restart, and update macOS.

What you can do: List the rented Macs on the account and check whether each one is online.
Retrieve login credentials for a rented machine.
Restart a machine and trigger macOS updates.
No individual tools are documented, so the exact operations are inferred from the server description.
When to use it: Useful when you rent Macs from Halfpenny Mac and want an assistant to check their status, get access details, or restart and update them without opening the web dashboard.
Requirements: Runs locally as an npm package via npx, so Node.js is needed. Requires a Halfpenny Mac account and an API token supplied in the HALFPENNY_TOKEN environment variable. Desktop only; network access to the Halfpenny Mac service is required.

Before you install

The server holds an API token that grants control over rented machines. It can expose machine credentials and perform actions that restart machines or change their macOS version, which may interrupt running work. Keep the token private and confirm destructive actions before running them.

Installation

In SourceWeft

Open Halfpenny Mac in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
