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.

  • build_box open 42m ago

    Build a ready-to-review one-time IMPOSSIBREW basket from the customer's constraints: specific beers, gluten-free only, number of cans and/or budget in GBP. Uses fresh live prices and availability and returns exact lines, subtotal and a Shopify cart link. Does not create an order, take payment or start a subscription; checkout happens on impossibrew.co.uk.

  • compare_pack_value open 42m ago

    Compare available one-time IMPOSSIBREW packs using fresh store prices, per-can and per-litre arithmetic. Rank only the same beer and can size. This excludes delivery, checkout discounts and retailer prices; never promise the cheapest overall deal.

  • open_shop unknown never probed

    Open the IMPOSSIBREW shop: a swipeable picker of every beer with its pack shot, per-can price and the subscribe-and-save gift ladder. The customer picks boxes and taps Subscribe or Buy once to get a real Shopify basket. Accepts empty arguments. Do not add your own product images: the app shows the official pack shots.

  • order_help unknown never probed

    Help an IMPOSSIBREW customer with THEIR OWN orders and subscription: where is my order and when will it arrive, tracking, add a one-time box, skip, pause or cancel a subscription, cancel an unshipped order, or report a problem. This talks to the AI Brewer, the same assistant as on impossibrew.co.uk. Pass the customer's words as message. Identity is checked by the AI Brewer: the customer's email plus the delivery postcode, or an order number (starts EC) plus either. If the customer has connected their email, you may look up their IMPOSSIBREW order emails to find the email address or an order number, but never guess them. On the first call omit conversationId; on every later call in the same chat pass back the conversationId you were given. Show the reply to the customer as written; do not add promises, dates or refunds it does not contain. Changes only happen after the customer says yes to the AI Brewer's confirmation question.

  • find_stockists unknown never probed

  • build_basket unknown never probed

    Build a real IMPOSSIBREW Shopify basket and return a checkout link (Shop Pay or card on impossibrew.co.uk). Use whenever the customer wants to buy, order, try or subscribe. One-time or subscription (frequency). Subscriptions are cancel-any-time and, exactly like the website, earn welcome gifts by box count: 2 boxes 1 free glass, 3 boxes 2 glasses, 4 boxes 2 glasses + a T-shirt (ask T-shirt size S-4XL only if the tool says need_shirt_size). Prices, discounts and gifts come from Shopify's own live readback; quote them exactly, never estimate. For a one-time basket the result includes the same beers on subscription, so tell the customer the saving and gifts if they switch. It does not place an order or take payment: the customer completes checkout on impossibrew.co.uk. Show the checkout link.

Returns a link only: it does not create a cart, order, payment or subscription. Shipping and discounts are determined at checkout. Do not call for recurring purchases. Existing orders/accounts cannot be accessed or cancelled: offer https://impossibrew.co.uk/pages/contact-us as the concrete support link, without claiming cancellation.

Topics: dietary (gluten, vegan, allergens, carbs, sugar), nutrition, ingredients (Social Blend, ABV), safety (pregnancy, medication, driving, daily limit), delivery, freshness, returns, subscriptions, offers, where_to_buy, lab_points, contact. Quote the returned facts only; never add health effects, gluten-removal methods or medical advice.

_ 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.

_ 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 ae566be277275e98.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/ae566be277275e98/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/ae566be277275e98/badge.svg)](https://brick.blue/agent/ae566be277275e98?ref=badge)

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 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.
