Overview

AI-generated overview

Vouchernaut is a remote MCP server for UK shopping: discount codes, product prices and price history, phone deals, events, airport parking and consumer rights.

What you can do
  • Search UK stores and their live discount codes and deals, and open one store's full offer list
  • Search products with prices, price-history notes and the price after the store's best code, and check one product's variants, stock and price history
  • Find recent price drops and judge whether a shop's current price is a real deal
  • Compare phone contracts and SIM-only plans, including total cost with announced rises
  • Look up events and things to do, airport parking prices, software and AI tool deals, and reader poll results
  • Calculate UK take-home pay and student loan repayments, and check refund rights with deadlines and the law behind them
When to use it
Useful when an assistant is helping someone shop or plan in the UK: finding working discount codes, checking whether a price is genuinely low, comparing phone or SIM deals, pricing airport parking, or answering questions about pay, student loans and refund rights.
Requirements
Remote streamable HTTP endpoint at vouchernaut.com; no packages, environment variables or headers are declared. A network connection is needed.
Before you install
Results include tracked affiliate links to retailers, so purchases made through them may earn the provider a commission. Prices, codes and terms come from third parties and can change; verify before buying. Tax, student loan and refund answers are projections or general guidance based on stated assumptions, not personal advice.

Installation

In SourceWeft

  1. Open Vouchernaut in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.vouchernaut%2Fdeals/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

search_stores

Find UK stores with discount codes

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 their codes (where the brand allows them here) and tracked links, a link to shop there and its vouchernaut.com page.

Parameterslimitqueryrequired

get_store_offers

Get a store's discount codes and deals

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.

Parameterskindstorerequired

search_products

Search products across UK stores

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>").

Parameterssorttypelimitqueryrequiredstoreon_salemax_pricemin_price

get_product

One product's price, code and history

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 (where the brand keeps its codes to vouchernaut.com, the saving and the store page that reveals the code), its price history (lowest, typical, now), delivery, the same product at other stores and a tracked link to buy.

Parametersproductrequired

price_drops

Products whose price just dropped

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.

Parameterstypelimitquerystoremax_pricemin_price

check_deal

Is this UK price a real 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.

Parametersqueryrequired

find_phone_deals

Compare UK deals for a phone

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.

Compare UK SIM-only plans

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.

Parameterssortlimitmonthsnetworkupgrademin_datamax_monthly

whats_on

What's on in a UK town or city

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.

Parameterscityrequireddatewhenlimitquerycategorythings_to_do

airport_parking

Compare UK 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`.

Parameterstofromtypelimitairportrequired

get_poll_result

Vouchernaut reader poll results

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.

Parameterspoll

find_software

Compare software and AI tools

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.

Parameterslimitquerycategory

calculate_take_home_pay

UK take-home pay after tax

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.

Parametersperregionsalaryrequiredpensiontax_codestudent_loanshours_per_weekpension_monthlypension_percentpension_on_qualifying_earnings

student_loan_repayments

UK student loan repayments and write-off

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.

check_refund_rights

UK refund rights for a purchase

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.
