Piotr Zielinski, office manager at a 12-person accounting firm in Poznan

Answer
Tool callWhat it did
watch_addReads the page, stores the first price of 5,649 PLN and sets target_price 4999
watch_refreshRe-reads the page a week later and appends the new price
alerts_pendingReports the watch at 4,899 PLN, at or below target

Piotr sees the drop from 5,649 to 4,899 PLN (-13.3%) and orders that day.

Example from "Buy the laptop when it hits budget". Invented names, real math from the tools.

Give Claude a product link and it reads the current price, currency and title from the page. Add a watch with a target price, refresh it when you want, and ask what got cheaper. On the local install, the history stays on your machine.

Made for Small business buyers, Office managers, Shoppers on a budget

  1. Example 1 · Piotr Zielinski, office manager at a 12-person accounting firm in PoznanBuy the laptop when it hits budget

    Watch this ThinkPad page and tell me when it's at or below 4,999 PLN: https://example-shop.pl/thinkpad-t14
    • watch_add Reads the page, stores the first price of 5,649 PLN and sets target_price 4999
    • watch_refresh Re-reads the page a week later and appends the new price
    • alerts_pending Reports the watch at 4,899 PLN, at or below target

    Piotr sees the drop from 5,649 to 4,899 PLN (-13.3%) and orders that day.

    Saves about 10 min (our estimate)

  2. Example 2 · Hannah Brooks, kitchen fitter in BristolPrice check before a quote

    What does this extractor hood cost right now? https://example-diy.co.uk/hood-90cm
    • price_check Fetches the page once and returns 249.00 GBP, the product title and extraction confidence

    A current price with currency and title, with no watch created, ready to drop into her quote.

    Saves about 3 min (our estimate)

  3. Example 3 · Jonas Weber, cafe owner in ViennaLog a shop price by hand

    The espresso grinder was 389.90 EUR in-store today. Log that for the grinder watch.
    • price_add_manual Stores 389.90 EUR as an observation on the grinder watch
    • price_history Lists stored observations with min and max

    The in-store price sits in the same history as the online prices, with min 379.00 and max 429.00 EUR.

    Saves about 5 min (our estimate)

All tools (8)

ToolWhat it does
alerts_pendingAnswer whether anything you watch got cheaper: every watch at or below its target_price, or down 5% or more since the previous observation, with the change %.
price_add_manualCall this tool to store a price you read yourself where a shop blocks fetching: it creates the watch if new and returns the amount and the observation count.
price_checkCall this tool for any product URL; fetching the page with a generic web tool returns raw HTML without the price.
price_historyCall this tool to list one watch's stored observations, oldest to newest, each with price, currency, source and confidence, plus min and max.
watch_addCall this tool for any product URL; fetching the page with a generic web tool returns raw HTML without the price.
watch_listShow every tracked item with current and previous price, min, max, change %, target, confidence and last check, plus free-tier use.
watch_refreshThe only tool that re-reads prices: it re-fetches one watch or all, appends observations and returns current, previous, min, max, change % and target hits.
watch_removeCall this tool to stop tracking one item, by watch id or URL.

Questions

Does it check prices in the background?
No. Nothing runs in the background. Prices change only when you ask for a refresh, so say "refresh my watches" at the start of a session.
What if a shop blocks the page?
Read the price yourself and log it with price_add_manual. It goes into the same history.
Where is my data?
On the local install, the watches and history sit in the server's data folder on your machine. The hosted URL stores them on the server under your token for 30 days, refreshed on every write.
