The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • get_glossary open 3h ago

    German wine terms explained, with their regional variants. Useful because the same institution carries different names by region: the seasonal tavern a winery runs itself is a Straußwirtschaft on the Mosel and in the Palatinate, a Besenwirtschaft in Württemberg and a Hecken- or Häckerwirtschaft in Franconia — and none of them is the same as a Gutsausschank, which may open all year. Omit the term to list all entries.

  • list_regions unknown never probed

    Lists all 13 German wine regions (Anbaugebiete) with their character, the number of wine towns and wineries in each, and how many events are coming up. Start here when the question is about German wine regions in general.

  • get_lage unknown 3h ago

    One Einzellage in full: Bereich, Großlage, planted area, the official vineyard number, the municipalities it spans, and the wineries of its town. It is NOT known which wineries actually farm vines in a given Lage — no public register holds that — so the wineries listed are those located in the town, and the answer says so.

    Full description of one wine region: its history, grape varieties and terroir, plus its wine towns and upcoming events.

  • search_lagen unknown never probed

    Search the 1.646 registered German Einzellagen (single vineyard sites) by name, town or region. The Einzellage is the smallest origin unit in German wine law and the name that appears on the label after the town ("Forster Ungeheuer", "Wehlener Sonnenuhr"). For the six regions of Rhineland-Palatinate the data is the official register of the Chamber of Agriculture and carries the vineyard number, Bereich, Großlage, planted area and the legal boundary; the Rheingau is currently sourced from Wikipedia and has no boundary. Note that a Lage name says where a wine grew, not how good it is. Where a winery names a Lage on its own website, get_lage returns that winery with the sentence it appeared in.

  • search_wineries unknown never probed

    Search ~5.900 German wineries by name, town, postal code or region, or geographically around a point. Filters for wineries that serve food (Straußwirtschaft, Gutsausschank), offer accommodation, or have a place for a camper van. Two further filters come from what a winery writes on its own website — grape variety and organic farming — and those two are deliberately incomplete: only about half of all wineries have a website that says so. Absence there is not evidence of absence. Returns contact details, address and coordinates.

  • get_winery unknown never probed

    Everything held about one winery: address, contact, opening hours, average rating, recent visitor comments, its upcoming events, the Einzellagen it names on its own website (which is not the same as the Lagen it farms — that is not publicly recorded), and a portrait assembled from its own website (hectares, grape varieties, organic farming, founding year) where that page could be read.

  • list_events unknown never probed

    Upcoming German wine events — Weinfeste, Hoffeste, Weinproben, Weinwanderungen — across all regions, or filtered by region, town or a radius around a point. Every event carries the source it was verified against and a link to its own page; the result also names the human-readable calendar page for the same selection, which is the thing to hand a person rather than retelling a list that changes daily.

  • search unknown never probed

    Free-text search across the whole directory — winery names, owners, towns and description texts. Use this for open questions where the exact name is unknown ("a winery near the Mosel with rooms", "Riesling from steep slopes"). For a known town or a radius around coordinates, search_wineries is more precise.

  • get_vintage unknown never probed

    What the weather did in one growing season, per wine region: mean temperature, sunshine hours and rainfall from April to October, compared with the 1991-2020 normal, plus the harvest volume where published. Measured data of the German Weather Service, for some regions back to 1881. IMPORTANT: these are measurements, not a verdict. A warm year is not a good year — what ends up in the glass depends on site, grape and winemaker. Do not present the numbers as a quality rating. Omit the year to get the whole series for a region.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/f96b059c5ac46414/badge.svg)](https://brick.blue/agent/f96b059c5ac46414)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
