Vouchernaut

Présentation

Vouchernaut est un guide d’achat britannique exposé sous forme d’outils MCP.

La carte apparaît à l’endroit de la balise. Ajoutez data-theme="dark" ou data-size="compact" à la balise pour la modifier. Le fichier contient tout ce qu’il lui faut : il ne fait aucune autre requête et ne dépose aucun cookie.

Ce que signifie chaque champ

Prompt pour l’IA

Collez-le dans un assistant de code IA, comme Claude Code ou Cursor, et il ajoutera la carte de Vouchernaut à votre site.

Markdown

Ajoute à mon site la carte mcp.tc de Vouchernaut, un serveur MCP. C’est un seul script statique : pas de build, aucun paquet à installer, aucun cookie.

Place cette balise là où la carte doit apparaître. La carte s’affiche juste avant elle :

```html
<script src="https://mcp.tc/w/vouchernaut.js" async></script>
```

Pour l’afficher ailleurs, mets ce conteneur à cet endroit et charge le même script une seule fois, par exemple avant `</body>`. Garde le lien à l’intérieur : les visiteurs sans JavaScript le voient.

```html
<div data-mcptc="vouchernaut"><a href="https://mcp.tc/i/vouchernaut">Vouchernaut on mcp.tc</a></div>
```

Options :
- `data-theme="light"` ou `"dark"` sur la balise ou le conteneur fixe les couleurs. Sans cela, la carte suit le mode clair ou sombre du visiteur.
- `data-size="compact"` donne une carte plus petite, sans l’accroche.
- La variable CSS `--mcptc-max-width` sur le conteneur ou un parent fixe la largeur (`520px` par défaut).
- `?lang=` dans l’URL du script choisit la langue de la carte : `en`, `it`, `fr`, `de` ou `es`.

Si le site a une Content Security Policy, autorise `script-src https://mcp.tc` et `img-src data:` (l’icône est intégrée).

Pour un README ou une autre doc en Markdown, utilise plutôt le badge :

   • get_store_offersdescription

     Every live discount code and deal Vouchernaut lists for one UK store, in the order its store page shows them: the code itself, what it saves, its terms and end date, how many shoppers said it worked or failed, and a link that opens the store with the offer. Some brands keep their codes to vouchernaut.com: those come without the code (`code_on_page`), linking to the store's vouchernaut.com page, where the shopper reveals it. The store can be named ("Arena Flowers"), or given by its slug or its vouchernaut.com page. Each link may earn Vouchernaut a commission, which every result discloses.

   Instructions du serveur

   Avant

   Vouchernaut is a UK shopping guide. Its tools answer with live data from vouchernaut.com: discount codes and deals for UK stores (with how many shoppers said each worked), product prices across stores with price history, phone and SIM-only deals with their full contract cost, what's on in UK towns, and airport parking. When you show a code, deal, product or plan, give the shopper its `url` as a link: it opens the store with the offer applied where the store allows it. Where an item has `affiliate: true`, say once that Vouchernaut may earn commission through the link (it never changes what's listed or the order). Prices are in pounds. Quote phone and SIM-only monthly prices with their upfront cost, length, total cost and any price rises; unlimited data is subject to fair use. Only say "lowest in 90 days" or "down from" when the result says so. Some brands keep their codes to vouchernaut.com: such an offer comes with `code: null` and `code_on_page: true`, and its `url` is the store's vouchernaut.com page, where the shopper reveals the code. Say the code is on that page; don't look for it elsewhere. search_stores gives each store's best few offers and get_store_offers a store's full list. search_products and price_drops give each product a `ref` that get_product takes. find_software's slugs work with get_store_offers. search and fetch cover the same data for research.

   • calculate_take_home_payLecture seule

     What a UK employee's pay comes to after income tax, National Insurance (category A), student loan and a workplace pension, for the current tax year, by the year, month and week, with each tax band, the sources and a link to the worked answer on vouchernaut.com. Worked on the year as a whole, as HMRC's rates are; a payslip works each pay period on its own, so it can be a few pounds a year different. Covers England, Wales, Northern Ireland and Scotland and everyday tax codes, not K codes, benefits in kind, other income or the self-employed. Information, not financial advice.

   • check_dealLecture seule

     Whether a product's price at a UK shop is a real deal, from Vouchernaut's own record of that shop's prices: pass a product page link from the shop, a barcode, a product's name or a `ref` ("<store>/<product>"). Gives the verdict on today's price (lowest we've recorded, no change, cheaper before and when), the shops selling the same product for less today, and a tracked link to buy. Says plainly when the shop isn't one whose prices are tracked. Never uses shops' own "was" prices or RRPs.

   • check_refund_rightsLecture seule

     The UK consumer rights that apply to something bought (faulty, not arrived, poor service or a change of mind), strongest first, each with its last day as a date and the law it comes from (Consumer Rights Act 2015, Consumer Contracts Regulations 2013), then what the way it was paid adds (section 75, chargeback, PayPal, buy now pay later) and where to go next. Legal information, not legal advice: it never decides a claim.

   • student_loan_repaymentsLecture seule

     What a UK student loan costs a month now, and whether it's cleared or written off first: a month-by-month projection to the plan's write-off on stated assumptions (pay rises and RPI, which the caller may change), with this year's threshold and interest rate, the total repaid and the sources. A projection, not a forecast, and information, not financial advice: it never says whether to pay a loan off early.
