Connects to used-Mac listings across eBay, Craigslist, OfferUp, Swappa, Facebook and Reddit. Muse can look up serial numbers, check asking prices and sold prices by configuration, search filtered listings with scam detection, verify individual listings, retrieve condition reports, and set price alerts.

Example request: "Find me a used 14-inch MacBook Pro with M3 Pro under $1500 and alert me when new ones appear."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Macfax to help me. It is a free service with an MCP server at https://macfax.com/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- lookup_mac_serial: Resolve a Mac serial number to its exact model, including 2021+ randomized serials whose characters encode nothing (so no character-decoder can read them). Also returns what that model is worth (the market block: sale estimate and asking band per configuration) and whether a veri
- get_mac_price_stats: What a used Mac configuration actually sells for AND what sellers are asking right now. The sold slice is the headline: verified-sale percentiles when the config has enough recent sales (sold.basis 'direct'; n and window ride along), else the asking band scaled by a measured clea
- get_mac_market_value: What a used Mac is worth, from the name Apple gives the model, e.g. "MacBook Pro (14-inch, 2021)" or "MacBook Air (13-inch, M4, 2025)". Returns every Apple Silicon configuration the name can mean, each with its sale estimate (verified sales, or the asking band scaled by a measure
- search_mac_listings: Live used-Mac listings aggregated across eBay, Craigslist, OfferUp, Swappa, Facebook and Reddit, with scam clusters, junk titles, classified-ad bait, auctions and stale/sold rows already filtered out. Every result deep-links to the source listing where the purchase happens. Filte
- check_mac_listing: The trust picture for one specific listing, by URL (eBay/Craigslist/OfferUp/Swappa/Facebook/Reddit) or Macfax listing id: whether Macfax knows it, whether it still passes every quality gate, scam/junk/classified/auction flags, when a scan last verified it live, its ask against th
- get_mac_report: A verified Macfax condition report as structured data: hardware-verified identity, Activation Lock / MDM / serial-match checks, coverage status, and the signing chain. Use when a listing or seller shares a macfax.com/r/ link and the buyer wants the facts behind it. status "supers
- create_mac_alert: Watch the market for a configuration: Macfax emails the given address when new matching listings appear. CONSENT CONTRACT: create an alert only for a user who explicitly asked for this alert on this email address. The first alert for a new email stays inactive until the email's o
- get_macfax_credit_balance: How many serial resolutions this API key has left, and what actually costs a credit. Only a brand new resolution is billed: a 2021+ (10 character) serial Macfax has never resolved and that this key has not looked up in the last 24 hours. Cached serials, pre-2021 serials, repeats
