How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability62
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 2076 tokens (~259/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage88
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 63% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
check_mac_listing Check a used-Mac listing before trusting it ~160
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 the configuration's typical asking band, the platform's own seller-reputation figures where the marketplace has them (seller_signals: eBay feedback, Swappa rating; null elsewhere), and whether a verified Macfax report is attached. Facts, not verdicts.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | – | A Macfax listing id (from search results). |
| url | string | – | The listing's URL on the source marketplace. |
No output schema declared.
No examples provided.
create_mac_alert Create a standing used-Mac listing alert ~257
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 owner clicks the confirmation link Macfax sends; nothing is emailed before that, and every alert email carries manage and unsubscribe links.
| Name | Type | Req | Description |
|---|---|---|---|
| config | string | yes | Macfax config key: family[-screen]-chip-year, optionally -RAMgb-STORAGEgb. Examples: macbook-pro-14-m3pro-2023, mac-studio-m2ultra-2023-192gb-1024gb. |
| string | yes | The user's own email address, exactly as they gave it. Confirmation is required before anything sends. Never a placeholder or an invented address: those are refused, and the per-caller limit is a few… | |
| max_price_usd | integer | – | Only alert under this asking price. |
| min_tier | string | – | – |
| ram_gb | integer | – | – |
| storage_gb | integer | – | – |
| under_typical | boolean | – | Only listings under the configuration's typical asking range. |
No output schema declared.
No examples provided.
get_mac_market_value Get what a Mac model is worth ~217
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 measured clearance ratio; basis labeled) and its live asking band, plus an estimate across them: a single mid when the name pins one configuration, a low-to-high range when Apple's name leaves the chip open. Apple Silicon Macs only. Use the sale estimate as the price of the Mac; asking is seller guidance.
| Name | Type | Req | Description |
|---|---|---|---|
| model | string | yes | The Mac's model name as Apple writes it, with a chip or a year: "MacBook Pro (14-inch, M3 Pro or M3 Max, Nov 2023)", "Mac mini (2023) with M2 Pro", "iMac (24-inch, M1, 2021)". |
No output schema declared.
No examples provided.
get_mac_price_stats Get used-Mac price statistics ~210
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 clearance ratio (sold.basis 'calibrated', ratio disclosed). The asking band (median/p25/p75 with sample size), per-channel medians with net-to-seller after fees, launch MSRP retention and Apple trade-in floor ride along as seller guidance. Use the sold estimate as the price of the Mac; use asking to set a list price. The slices are separate and never blended — preserve the basis label when quoting.
| Name | Type | Req | Description |
|---|---|---|---|
| config | string | yes | Macfax config key: family[-screen]-chip-year, optionally -RAMgb-STORAGEgb. Examples: macbook-pro-14-m3pro-2023, mac-studio-m2ultra-2023-192gb-1024gb. |
No output schema declared.
No examples provided.
get_mac_report Fetch a verified Macfax report ~120
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 "superseded" means the same Mac was re-verified more recently under a newer report; treat the payload as historical state, not current.
| Name | Type | Req | Description |
|---|---|---|---|
| report_id | string | yes | The 8-character report id from a macfax.com/r/<id> URL. |
No output schema declared.
No examples provided.
get_macfax_credit_balance Check Macfax credits ~120
How many credits this API key has left, and what costs one. One credit answers one distinct serial, any Apple device and any year, and the same serial again within 24 hours is free. Answers that come back retry or unsupported, and every other tool, are free. Without credits, a free key gets 25 brand new 2021+ resolutions and 200 distinct serials a day. Call this before a large batch of serials to find out whether it can be finished. Without a key it reports the anonymous allowance instead.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
lookup_mac_serial Look up an Apple serial number ~335
Resolve a Mac, iPad or iPhone serial number to its exact model, including 2021+ randomized serials whose characters encode nothing (so no character-decoder can read them). status says what came back: resolved, unknown_serial (no such serial; check it), unsupported (a real device whose model cannot be identified yet), or retry (temporary, never charged). device_type is Apple's device class (Mac laptops, Mac desktops, iPad, iPhone). Also returns the device's record on Macfax: the month it was first seen, how often it has been looked up (first time, 2 to 5, or 6 or more), from how many countries in 30 days, and any listing, verified report or sanitization record on file. For a Mac, also returns what that model is worth (the market block: sale estimate and asking band per configuration). Lookup is advisory and cannot verify condition, Activation Lock, or possession; a Macfax report can. With credits, one credit answers one distinct serial, any Apple device and any year, and the same serial again within 24 hours is free.
| Name | Type | Req | Description |
|---|---|---|---|
| context | string | – | Optional. Why the serial is being looked up: inventory (counting devices an organization holds), intake (devices arriving for refurbishment, trade-in or repair), resale (pricing or listing one to sel… |
| serial | string | yes | The device's serial number: 10 characters on 2021+ devices (a letter first, never a vowel), 11-12 on older ones. |
No output schema declared.
No examples provided.
search_mac_listings Search live used-Mac listings ~287
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. Filter by configuration, family, chip, RAM, storage, price ceiling, and verified-report tier.
| Name | Type | Req | Description |
|---|---|---|---|
| chip_tier | string | – | e.g. m3, m3pro, m4max, m3ultra |
| config | string | – | Macfax config key: family[-screen]-chip-year, optionally -RAMgb-STORAGEgb. Examples: macbook-pro-14-m3pro-2023, mac-studio-m2ultra-2023-192gb-1024gb. The year may be omitted when the rest pins one bu… |
| family | string | – | Coarse browse by product family. |

| max_price_usd | integer | – | – |
| min_tier | string | – | free/premium = only listings with a verified Macfax report attached. |
