Nothing serious here today
Today is the operative word: we check Vouchernaut every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

If a tool disappears, we record the date.
airport
airport_parking
Car parks UK parking providers sell at the UK's main airports: meet and greet, park and ride and on-airport, with transfer times, terminals, Safer Parking status, compulsory charges on the day and, for given drop-off and pick-up times, the full price including known fees, with a tracked link to book. Prices are only for a stay given by `from` and `to`.
calculate
calculate_take_home_pay
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.
deal
check_deal
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.
fetch
fetch
The full text of one result from search: a store's live codes and deals with their links, a product's price and code (a code itself only where the brand has approved AI assistants, else the store's vouchernaut.com page), a phone's deals, or a buying guide.
phone
find_phone_deals
Every deal UK retailers list for one phone on Vouchernaut's phone finder: monthly price with its upfront cost, contract length, total cost over the contract with announced price rises included (and each rise in pounds and month), data, network and seller, with a tracked link to the retailer. Filter by storage, colour, condition, budget, network, contract length and data.
poll
get_poll_result
Results of Vouchernaut's reader polls (UK shoppers answering short questions in its guides): the question, each answer's votes and share, and the poll's page to cite. Shares are quotable ("one in three readers") only once a poll has 100 answers. Without `poll`, it lists the polls.
price
price_drops
Products across UK stores whose price fell in the last 30 days from a price the store had held for at least 28 days, biggest fall first. Each comes with the old and new price and a tracked link. Narrow by search words, product type, store or price.
product
get_product
One product, by its `ref` ("<store>/<product>") or its vouchernaut.com page: every variant's price and stock, the store's best discount code that covers it and the price after it (the code itself only where the brand has approved AI assistants, else the saving and the store page that reveals it), its price history (lowest, typical, now), delivery, the same product at other stores and a tracked link to buy.
products
search_products
Search the products UK stores sell through Vouchernaut (flowers, gifts, hampers, candles, homeware and more): title, store, price, the price after the store's best discount code, honest price-history notes ("Down from", "Lowest in 90 days"), the same product at other stores, and a tracked link to buy. Each product has a `ref` ("<store>/<product>").
refund
check_refund_rights
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.
search
search
Search Vouchernaut, a UK shopping guide: stores with discount codes, products and their prices, phones on its phone finder, and its buying guides. Each result has an id, a title and its page's URL.
sim
sim_only_deals
SIM-only plans UK retailers list on Vouchernaut: monthly price with upfront cost, contract length, total cost with announced price rises included, data, network and seller, with a tracked link. Filter by data, budget, network and contract length. Unlimited data is subject to fair use.
software
find_software
Software and AI tools Vouchernaut covers (AI assistants, meeting notes, dictation, website builders, email marketing and more): price, free plan, trial, platforms, review scores and any live deal, with each tool's vouchernaut.com page. Each tool's slug is also its store's slug. Without `category`, it covers every category and lists them.
store
get_store_offers
Every live discount code and deal Vouchernaut lists for one UK store, in the order its store page shows them: what each saves, its terms and end date, how many shoppers said it worked or failed, and a link that opens the store with the offer. A code itself comes only where the brand has approved AI assistants; any other comes without it (`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.
stores
search_stores
Search the UK stores Vouchernaut lists by name or category ("flowers", "Currys", "phone cases"). Each store comes with how many live codes and deals it has, its best few offers with tracked links (each code itself only where the brand has approved AI assistants, else its vouchernaut.com page), a link to shop there and its vouchernaut.com page.
student
student_loan_repayments
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.
whats
whats_on
Gigs, comedy, theatre, festivals, exhibitions and things to do in about 90 UK places, from ticket and experience sellers: title, date and time, venue and address, the lowest price where the seller's price includes its fees, and a tracked link to buy tickets. Filter by when, a date, category or words.

Vouchernaut — questions
Answers built from our own checks of this server.
What can Vouchernaut do?
It exposes 17 tools, read directly from the server on our last check. Among them: airport_parking, calculate_take_home_pay, check_deal, check_refund_rights, fetch, find_phone_deals and 11 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
Is Vouchernaut working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 254 ms. The bar chart above shows every period we have measured.
How do I connect Vouchernaut?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Vouchernaut need an API key?
No. Vouchernaut completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 17 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Vouchernaut?
It answers our handshake in 254 ms on average, which is faster than 66% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
