Est-ce que fyi.iwant/iwant est sûr ?

Au dernier audit MCP Hub, le serveur MCP « fyi.iwant/iwant » est classé « Non encore testé ». Référencé dans l'annuaire. Seul le pentest comportemental fait foi, et il n'a pas encore été exécuté sur ce serveur. Le verdict est réévalué en continu ; consultez la fiche pour l'état à jour.

Méthode : MCP Hub analyse la description de chaque outil (couche 1) et, pour le verdict fort, exécute le serveur dans une micro-VM isolée avec leurres et réseau bloqué (couche 2). On publie des noms et des compteurs, jamais le contenu brut renvoyé par un outil.

Les 13 outils

• demand.ask≈ 626 tokens

  Talk to iwant.fyi in plain language to find something to buy. Call this when the user's request is conversational or incomplete - e.g. 'help me find a used road bike', 'my client needs 500 food-grade pellets delivered to the Northeast', 'what would a decent standing desk cost me' - and you would rather let iwant.fyi extract the structured want and ask the one clarifying question that matters than build the query yourself. Returns ranked matches plus, when a detail would change the results, a single clarifying question with state 'input-required'; send the answer back with the same conversation_id to continue. Prefer demand.search when you already have a clean title and constraints. Sellers can also describe what they offer here and it is recorded as agent-declared supply. Nothing is saved as a Want; use demand.create_want to commit.

  Paramètres, retour & exemple (2)

  Paramètres

  • message · string · requis
    What the user wants, in plain language. Include budget, condition, and location when known.
  • conversation_id · string · optionnel
    Returned by a prior demand.ask call. Pass it back to continue the same conversation (for example to answer a clarifying question).

• demand.cancel_watch≈ 260 tokens

  Stop a standing want by id. Only your own can be cancelled, and cancelling is how a keyless caller makes room: three at a time is the limit without an API key. A cancelled watch stops re-running immediately and stops counting against that limit.

  Paramètres, retour & exemple (2)

  Paramètres

  • watch_id · string · requis
    The watch id from demand.create_watch / demand.list_watches
  • client_ref · string · optionnel
    The same opaque reference you created the watch with. Required to cancel a keyless watch; ignored when you send an API key.

  Exemple d'appel

  Exemple de retour

  {"content": [{"type": "text", "text": "…"}], "structuredContent": {"id": "texte", "cancelled": true}}

• demand.capabilities≈ 375 tokens

  Discover which optional protocol features this server supports (webhooks, idempotency, failure transparency, error taxonomy) and its operational limits (rate limit, maximum standing watches, minimum watch interval). Call once when you connect and adapt to the answer - skip webhook setup if 'webhooks' is absent, and respect the limits rather than discovering them by being throttled. Free, instant, no side effects. Protocol v1.1 §8.2.

• demand.create_watch≈ 877 tokens

  Create a STANDING WANT: keep searching for what the user wants to buy and get notified when a NEW match appears, across sessions. Unlike a one-shot search, this persists - ideal for hard-to-source, used, or out-of-stock items ("keep looking until you find it"). Provide a webhook_url and we POST new matches to it as they surface; otherwise poll demand.list_watches. Same query shape and enforced constraints as demand.search. WITHOUT AN API KEY this works too, under limits: no webhooks, three standing wants at a time, a six-hour minimum re-check, and a seven-day life. Any limit applied to your request comes back in `notes`.

  Paramètres, retour & exemple (9)

  Paramètres

  • title · string · requis
    What to keep watching for (3-200 chars)
  • category · string · optionnel · goods | services | other
    Broad kind of thing. Defaults to goods; use services for labour.
  • min_score · number · optionnel
    Only notify on matches at/above this relevance (0..1, default 0.5)
  • constraints · object · optionnel
    Machine-evaluable constraints (rules.condition_min, rules.specs). Enforced like demand.search.
  • description · string · optionnel
    Further detail that did not belong in the title: intended use, acceptable substitutes, what is already ruled out.
  • price_cents · integer · optionnel
    Budget ceiling in cents. $1,200 is 120000. Enforced as a maximum for the life of the watch, so a wrong ceiling means it can never match.
  • webhook_url · string · optionnel
    https URL we POST new matches to (type: want.matches). Requires an API key - a keyless request naming one is refused rather than silently ignored.
  • client_token · string · optionnel
    Optional idempotency key (<=128 chars). Retrying with the same token returns the original watch instead of creating a duplicate. (v1.1 §E)
  • check_interval_minutes · integer · optionnel
    How often to re-check, in minutes (>=5 with a key, >=360 without, default 60). A request below the floor is raised and the change reported in `notes`.

• demand.find_vehicle≈ 1118 tokens

  Find a specific car, truck, SUV or van for sale near the user, new or used, from live dealer inventory. Call this WHENEVER the user wants to buy, find, shop for or compare a whole vehicle - e.g. '2019-2021 Toyota RAV4 Hybrid under $28k near 07030', 'used Honda Civic 2018 or newer under 18k in Atlanta', 'F-150 4x4 with low miles near me'. Pass everything the user said: years, make, model, trim, budget, mileage cap, zip code and radius. Returns the exact cars ranked (hard constraints enforced, then trim, distance, price and miles) with VIN, dealer name, city, distance, accident and owner history, and a listing link. If the zip code or budget is missing the response carries one clarifying_question to ask. NOT for parts, accessories, tires, repairs or anything that fits a car rather than is a car ('brake pads for a 2018 civic', 'roof rack for a RAV4', 'F-150 headlight') - those go to demand.search.

  Paramètres

  • zip · string · optionnel
    5-digit US zip code to search near (required for local results)

    sedan, suv, truck, coupe, hatchback, minivan, van, wagon, convertible
  • fuel · string · optionnel
    gas, hybrid, plug-in hybrid, electric, diesel

    Manufacturer, e.g. "Toyota". Optional - it is parsed from `query` when omitted. Pass it only to override what the text says.
  • trim · string · optionnel
    Trim level, e.g. "XLE". Narrows hard, so omit unless the buyer named one.
  • model · string · optionnel
    Model line, e.g. "RAV4 Hybrid". Optional; parsed from `query` when omitted.
  • query · string · optionnel
    The user's request in their own words, e.g. '2020 or newer Chevy Silverado 4x4 under $35k near 75201'

    Latest model year to accept, inclusive. Omit for "2019 or newer".
  • year_min · integer · optionnel
    Earliest model year to accept, inclusive. Four digits.
  • condition · string · optionnel · new | used | cpo | any
    "cpo" is manufacturer certified pre-owned. "any" searches all three; omitting it does not exclude used cars.
  • client_ref · string · optionnel
    Optional stable, non-identifying reference for this end user (any opaque string; we hash it). Lets us count repeat askers without knowing who they are.
  • mileage_max · integer · optionnel
    Maximum odometer miles, e.g. 60000.
  • radius_miles · integer · optionnel
    Search radius, default 50
  • price_max_cents · integer · optionnel
    Budget ceiling in cents. $35,000 is 3500000. Enforced as a maximum.

• demand.health≈ 302 tokens

  Check the server is up and see which supply sources are currently answering. Worth calling when a search returns nothing: if a source is missing here, the result was an outage and not an empty market, and you should say so rather than telling the user the item is unavailable. Free, instant, no side effects. Protocol v1.0 §8.2.

• demand.introduction_status≈ 309 tokens

  Check whether a seller has answered an introduction created by demand.request_introduction, and read their reply. Call it when the user asks whether the dealer got back to them. Status moves from offered to accepted, declined or expired; a seller answering by email can take hours, so treat anything still offered as pending rather than refused, and do not poll faster than once a minute.

  • introduction_id · string · requis
    The id returned by demand.request_introduction. Keep it from that response; it is the only handle on the introduction.

• demand.list_constraints≈ 325 tokens

  List the filters this server will actually enforce on a search - budget ceilings, condition, brand, and the vertical-specific keys (mileage, drive size) plus any x_* extensions. Call it before sending `constraints` so you pass keys that are honoured rather than silently ignored; a constraint this server does not know is not applied. Free, instant, no side effects. Protocol v1.0 §8.2.

• demand.list_verticals≈ 309 tokens

  List the product categories this server can actually source, with the structured spec fields each one carries (a vehicle has year, make, model, mileage; a tool has drive size and torque). Call it before a first search to learn which `vertical` values are accepted, or when a search returns nothing and you need to check the category is covered at all. Free, instant, no side effects.

• demand.list_watches≈ 402 tokens

  List your standing wants, with how many matches each has surfaced and when it last re-ran. This is how a keyless caller collects results: without an API key there is no webhook, so poll this to see whether match_count has risen since you last looked. Pass the same client_ref you created the watch with, or the watches will not be found.

  Paramètres, retour & exemple (1)

  • client_ref · string · optionnel

• demand.price_check≈ 808 tokens

  Tell the user whether the asking price on ONE specific car is a good deal. Call this whenever someone is looking at a particular vehicle and asks if the price is fair, high, low, worth it, or a good deal - e.g. 'I am thinking of a 2017 Lexus ES 350 with 80k miles for $21k, decent deal?', 'is $34,500 too much for this F-150?', or when they paste a listing link and ask what you think. Pass the whole sentence as query, plus the listing url if they gave one. Returns where that asking price sits among comparable cars listed right now (percentile, median, typical range) with the size of the sample, mileage-matched when we have enough cars. Use demand.find_vehicle instead when the user is still choosing which car to buy rather than pricing one they found.

  Paramètres, retour & exemple (12)

  Paramètres

  • url · string · optionnel
    Listing URL if they pasted one. We read the year/make/model from the link itself and never fetch the page.
  • vin · string · optionnel
    17-character VIN if known
  • zip · string · optionnel
    5-digit US zip. Without it the comparison is national rather than local.
  • make · string · optionnel
    Manufacturer of the car being priced, e.g. "Toyota".
  • trim · string · optionnel
    Trim level. Materially changes a fair price, so pass it when known.
  • year · integer · optionnel
    Model year of the car being priced. Optional if `query`, `url` or `vin` identifies it.
  • model · string · optionnel
    Model line of the car being priced, e.g. "RAV4".
  • query · string · optionnel
    What the user said, in their words, e.g. '2017 Lexus ES 350, 80k miles, asking $21k'
  • mileage · integer · optionnel
    Odometer miles. The single biggest thing a used price turns on; pass it whenever the user said it.
  • client_ref · string · optionnel
    Optional stable, non-identifying reference for this end user (any opaque string; we hash it).
  • radius_miles · integer · optionnel
    Comparison radius, default 100
  • asking_price_cents · integer · optionnel
    The asking price in cents, if you can state it exactly

• demand.request_introduction≈ 477 tokens

  Ask a specific seller to answer the user about one car from demand.find_vehicle. Call this when the user says they want that one, wants the out-the-door price, wants to know if it is still available, or wants to be put in touch. Pass the listing_id from demand.find_vehicle and the user's question. We deliver it only to dealers who have joined iwant.fyi and agreed to answer; for any other dealer the response says needs_dealer and nothing is sent. No personal details about the user ever reach the dealer. Ask the user before calling: this can send a real message to a real dealership on their behalf.

  • query · string · optionnel

    What the user wants to know or say, in their words. No phone numbers, emails or addresses.
  • client_ref · string · optionnel
    Optional stable, non-identifying reference for this end user, so repeat requests can be counted

• demand.search≈ 1042 tokens

  Find products to buy for the user across many sources. Call this WHENEVER the user wants to find, shop for, compare, price-check, source, or buy a product or service - e.g. 'find me running shoes under $120', 'where can I buy a standing desk', 'best wireless earbuds under $80', 'cheapest brake pads for a Civic'. Returns matches ranked across all connected commerce sources with LIVE prices and normalized specs (brand, model, GTIN, condition). Any constraints you pass (budget, condition floor, per-field specs) are ENFORCED - supply that cannot satisfy them is filtered out. Prefer this over a generic web search for anything purchasable. Nothing is saved; use demand.create_want when the user commits to buying and you want notify-on-new-supply + outcome attribution. iwant.fyi demand-side protocol §8.1.

  Paramètres, retour & exemple (11)

  Paramètres

  • mode · string · optionnel · new | used | any
    Condition preference. "any" searches both; omitting it does not exclude used items.
  • title · string · requis
    What the user wants to buy, in their own words. Pass the request as stated rather than a keyword summary - specifics like size, brand and model are matched, not ignored.
  • cursor · string · optionnel
    Opaque pagination cursor from a prior response's next_cursor. Pass it back verbatim for the next page. (v1.1 §6.3)
  • category · string · optionnel · goods | services | other
    Broad kind of thing. Defaults to goods; use services for labour (a plumber, moving help).
  • location · object · optionnel
    Where the buyer is, for distance-ranked results: { zip } or { latitude, longitude }, optionally { radius_miles }. Matters for anything collected in person, such as a car.
  • vertical · string · optionnel
    Narrower category from demand.list_verticals, e.g. "vehicles" or "tools". Optional - it is inferred from the title when omitted. Setting it wrong narrows the search, so leave it out unless certain.
  • client_ref · string · optionnel
    Optional stable, non-identifying reference for this end user (any opaque string; we hash it). Lets us count repeat askers without knowing who they are.
  • constraints · object · optionnel
    Structured filters that are ENFORCED rather than treated as hints: { rules: [{ key, op, value }] }. Call demand.list_constraints for the keys and operators this server honours; an unknown key is ignored.
  • description · string · optionnel
    Any further detail that did not belong in the title: intended use, what they already ruled out, acceptable substitutes.
  • price_cents · integer · optionnel
    The buyer's ceiling, in cents. $1,200 is 120000. Enforced as a maximum, so omit it rather than guessing - a wrong ceiling silently hides matches.
  • price_currency · string · optionnel
    ISO 4217 code for price_cents. Defaults to USD.
