zzd MCP

A read-only MCP server operated by the Swiss web studio zzd, providing tools to query data from their free consumer sites including grocery price comparisons, civil wedding venue listings, cantonal rent references, electric vehicle cost-per-kilometer calculations, and map poster availability.

Endpoint and access

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Read-only tools from zzd (https://zzd.ch), a small Swiss studio that runs free sites for everyday questions in Switzerland: grocery prices across Migros, Coop, Lidl, Aldi, Denner, Volg and Aligro's promotions (Schnäppchen Jäger), places for a civil wedding (Trauungslokale Schweiz), usual rents by canton from the federal statistics (Mietcheck), what electric cars cost per km (EV cost comparison), and map posters (MappaMuse). Each result names its source and date, links the page on the zzd site and carries its caveats (a price has a date; a published wedding date is not always a free one; rents are cantonal averages; EV offers are a dated snapshot).

search_grocery_prices — Search Swiss grocery prices (Schnäppchen Jäger)

Advertised by the server during the last successful anonymous check.

Advertised read-onlyOpen-world

Search the grocery catalogue of Schnäppchen Jäger (schnaeppchenjaeger.zzd.ch, a free Swiss price comparison by zzd) across Migros, Coop, Lidl, Aldi, Denner and Volg, plus Aligro's weekly promotions. Returns products with pack price, price per unit, offer flag, the date each price was read, and a link to each product's comparison page. Prices are the shops' online prices, not branch shelf prices. Counts as one search of the site's free daily allowance (5 a day per connection without an account; calls through Claude's connectors share 300 a day). Each product links its comparison page.

find_wedding_venues — Find civil wedding venues in Switzerland (Trauungslokale Schweiz)

Advertised by the server during the last successful anonymous check.

Advertised read-onlyOpen-world

Find places for a civil wedding in Switzerland as cantons and municipalities publish them (registry offices and outside venues such as castles), from Trauungslokale Schweiz (traulokale.zzd.ch, a free finder by zzd). Filter by canton (code, slug or name), town, text, guests, or a published ceremony date or date range. Important: most offices publish no dates; and where datesShowAvailability is false a published date is NOT known to be free. The date is always booked with the registry office. Each venue links its page.

rent_reference — Usual rent in a Swiss canton (Mietcheck)

Advertised by the server during the last successful anonymous check.

Advertised read-onlyOpen-world

The usual net monthly rent by flat size in a Swiss canton, from the Federal Statistical Office (BFS), via Mietcheck (mietcheck.zzd.ch, free, by zzd). Give a canton or a place (postal code or municipality); with rooms and the net rent it also says whether that rent is below, within or above the usual range. A place in several cantons returns the candidates to choose from. Cantonal averages only: not street level, not legal advice. The result links the matching Mietcheck page.

Advertised by the server during the last successful anonymous check.

Advertised read-onlyOpen-world

Optional driving profile. The offers are a dated, hand-collected snapshot, not live prices; the model is calibrated for canton Aargau. The result links the comparison page.
