Is erntewerk free to use?
Not measured yet.
What tools does erntewerk have?
4 tools: produce_wholesale_price, produce_season, produce_price_trend, produce_market_overview.
Is erntewerk safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Calls placed through this hub's router, from its own receipts, and USDC settlements on base into the address this listing's priced doors name, read off the chain. Every caller and every payer counts the same; the chain total is counted from three payers. The address also stands behind 118 other origins: the chain figures are the gateway's, not this listing's alone. How it is counted.

_ what it can do 4 tools
4 never probed 0 of 4 classified

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.

  • produce_wholesale_price unknown never probed

    Returns the most recent weekly wholesale price quotes from the German Federal Office for Agriculture and Food (BLE) market and price report for fruit and vegetables: median, minimum and maximum in EUR per 100 kg over all quoted varieties and sizes, per country of origin, for the nationwide aggregate or a named wholesale market (e.g. Berlin, Hamburg, München), and the price change against the report four weeks earlier, computed only from identical quotes (same variety, size, origin and market) so a change in the variety mix does not show up as a price change. Accepts German or English produce names. These are wholesale quotes, not retail shelf prices. Preis 0.002 USDC je Aufruf, Abrechnung über x402.

  • produce_season unknown never probed

    Measures the season situation of a fruit or vegetable from the nationwide aggregate of the BLE wholesale market report instead of a fixed calendar. Returns the share of German-origin quotes in the current report week, whether the product was quoted in that week at all, the main origins, the weekly shares of the current report year and a monthly profile of the German share across all years contained in the report file. domestic_in_season is true when at least a quarter of the current report week's quotes are of German origin, false when fewer, and null with a reason when the product is not quoted in the current report week; the raw shares are returned so callers can apply their own threshold.

  • produce_price_trend unknown never probed

    Returns the weekly median wholesale price in EUR per 100 kg of a fruit or vegetable from the BLE market report (nationwide aggregate by default, or one origin) for up to the last 26 reported weeks, the price change between the first and the last week computed only from identical quotes (same variety, size and origin), and for context the latest official harmonised annual inflation rates in Germany for fruit (CP0116) and vegetables (CP0117) from Eurostat. Wholesale quotes and consumer price statistics are kept in separate fields and are never mixed into one number. Preis 0.002 USDC je Aufruf, Abrechnung über x402.

  • produce_market_overview unknown never probed

    Bundle answer from the BLE wholesale market and price report for fruit and vegetables: for the latest reported week (or a given week of the current report year) every quoted product group with the nationwide median price in EUR per 100 kg, the number of quotes, the price change against the report four weeks earlier (computed only from identical quotes: same variety, size and origin), the share of German-origin quotes and the main origin, sorted by name or by price change. Use it to plan menus, purchasing or content around what is cheap and in season. Wholesale quotes, not retail prices. Preis 0.005 USDC je Aufruf, Abrechnung über x402.

_ try it over mcp 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.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 9f8921682c37cba9.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/9f8921682c37cba9/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we knowoff the mcp door
card completeness
80%

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.

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