How do I install the macfax mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

It reads `MACFAX_API_KEY` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

Recorded tools

Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.

Tool	What it does
search_mac_listings	Live listings across eBay, Craigslist, OfferUp, Swappa, Facebook and Reddit. Scam clusters, junk titles, classified-ad bait, auctions and stale/sold rows are already filtered out; every result deep-links to the source.
get_mac_price_stats	What an exact configuration actually sells for — verified-sale percentiles (basis direct) or an estimate scaled from the asking band by a disclosed clearance ratio (basis calibrated) — plus the asking median/p25/p75 with
check_mac_listing	One listing's trust picture: known to Macfax, still live, flags, ask vs the typical band, the platform's own seller reputation where it exists (eBay feedback, Swappa rating), verified report attached.
lookup_mac_serial	Serial to model and year for any Mac, including 2021+ randomized serials. Also cross-references verified Macfax reports. Human twin: [macfax.com/lookup](https://macfax.com/lookup).
get_mac_report	A verified Macfax condition report (Activation Lock, MDM, serial-match checks) as data.
create_mac_alert	A standing watch: daily email when new matching listings appear. Human-confirmed: nothing sends until the email's owner clicks the confirmation link.
