Which MCP servers are iwant.fyi's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Should an agent connect itNot proven either way yet

Whether its tools do the product's job has not been judged yet.

Once connected

Keep approval on for demand.cancel_watch: they delete, send or pay without saying so.
demand.create_watch, demand.cancel_watch change data without a sign-in: anyone with the address can call them.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Every tool passes all six checks.

What an agent can do with it

not sure · search multiple supply sources for ranked product matches
not sure · post a standing want that an AI agent acts on
not sure · add demand asks to an agent through MCP or an SDK

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

Tools that delete, send or pay, marked as not destructive: demand.cancel_watch
Tools that change data, on a server that answers without a sign-in: demand.create_watch, demand.cancel_watch

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

demand.search
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…
demand.find_vehicle
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…
demand.price_check
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…
demand.request_introduction
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…
demand.introduction_status
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…
demand.list_verticals
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…
demand.list_constraints
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…
demand.health
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…
demand.capabilities
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…
demand.create_watch
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…
demand.list_watches
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…
demand.cancel_watch
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…
demand.ask
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'…

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "iwant": {
      "type": "http",
      "url": "https://iwant.fyi/api/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http iwant https://iwant.fyi/api/mcp

Add to Cursor Add to VS Code

claude.ai, ChatGPT and other clients: add https://iwant.fyi/api/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
