stay-cost-brain
Registry code: dda05936833bdb08
Stay Cost Brain covers tourist and city taxes on overnight stays: the amount charged on top of the room price, taken from each tax authority's own pages or the law, with the source and the date checked. tourist_tax works out the tax for a stay (place or town, dates, guests, type of stay), night by night, with seasons, star ratings, night caps and children's exemptions. Places not yet researched return researched=false. It has no room prices and does not book: hotels_link returns a link where the person sees live prices and books themselves. Sister services: Car Rental Brain (car hire)…

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.
list_places open 2h ago
Every place with a researched tourist-tax table: name, country, today's headline rate, the date it was checked, the next re-check date, the towns that set their own tax, and the page with every rate and source.
{ "type": "object", "properties": {}, "additionalProperties": false }arguments 5 linesget_capabilities unknown never probed
What Stay Cost Brain covers: the researched places, how the tax figures are sourced and dated, what it does not do (no room prices, no booking), and the sister services.
{ "type": "object", "properties": {}, "additionalProperties": false }arguments 5 linestourist_tax unknown never probed
The tourist tax for one stay, worked out night by night: each tax that applies (regional and city parts separately), the amount or the range when the star rating or type of stay is not given, how many nights are charged, how it is paid, announced changes in force on those nights, and the official source and date for each. Accepts a researched place or any town; towns outside the researched places return researched=false. Percentage taxes need room_price_total. Residents', medical and other special exemptions are listed in `rules`, not applied.

Every tourist-tax rule for one researched place: each tax with its authority, legal basis, rates by type of stay, season and area, night caps, exemptions, how it is paid, valid dates and status (verified, inferred, announced), with source links and dates.

A link to live hotel and rental prices for a place or any town and the given dates and guests (Stay22, showing Booking.com, Expedia, Agoda, Vrbo and others). The person sees prices and books there; this tool returns no prices and books nothing. Stay Cost Brain may earn a commission on bookings.

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.
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.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - 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. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's iddda05936833bdb08.

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.
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.
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.
