Macfax — Claude Code MCP server: what it does, how to install
Used-Mac intelligence server that verifies Apple serials, tracks resale prices, and pulls clean classifieds directly into your AI assistant.
claude mcp add --transport http macfax https://macfax.com/mcpWhat Macfax does
Macfax connects your assistant to secondary Apple market data. The service handles serial lookups across Mac, iPad, and iPhone lineups, covering modern randomized codes introduced in 2021. Queries return hardware specifications, launch year, MDM presence, and Activation Lock checks alongside estimated resale valuations.
The server inspects listings from platforms like Swappa, eBay, Craigslist, and Reddit. Scam patterns, expired posts, and auctions are stripped out prior to ingestion. Pricing figures distinguish actual concluded sales from asking ranges while factoring in platform fee deductions.
Basic functionality runs over remote HTTP at https://macfax.com/mcp without credentials. Adding an optional MACFAX_API_KEY expands rate limits roughly tenfold, and checking your credit balance fails without that environment variable.
What it helps with
- calculate realistic resale value for a specific Mac configuration
- verify an Apple serial number against MDM and Activation Lock
- browse live Mac listings filtered of scams and stale ads
- schedule daily email alerts for newly listed hardware
Example prompts for the agent
- What is a 2021 MacBook Pro 14-inch selling for right now?
- Look up this Mac serial number and verify if MDM is active.
- Search current Swappa and eBay listings for an M2 Mac mini.
