[Stay Cost Brain]

Stay Cost Brain MCP server

Tourist and hotel taxes, for AI assistants. What a stay really adds on top of the room price: the tourist, city, occupancy or hotel tax, taken from each tax authority's own pages, regulations or official gazette, with the source and the date it was checked, and worked out night by night for the dates and guests.

Free. No API key. No login. Read-only.

MCP endpoint (streamable HTTP):

https://staycostbrain.com/mcp

Why it exists

Booking sites show the room price. The tax on top is often charged at the hotel, differs by star rating, season and age, and in many places is stacked from state, regional and city parts. Stay Cost Brain keeps sourced, dated tables for 71 places in 18 countries (including 27 in the US) and answers with the amounts, so an assistant can say what a stay will really cost.

Tools

ToolWhat it answers
get_capabilitiesWhat is covered, how figures are sourced and dated, what it does not do
list_placesEvery researched place: headline rate, check date, re-check date, towns with their own tax
tourist_taxThe tax for one stay, night by night: each tax separately, amount or range, nights charged, how it is paid, announced changes, source and date
place_rulesEvery rule for one place: rates by type of stay, seasons, caps, exemptions, status, sources
hotels_linkA link to live hotel and rental prices for the dates and guests, where the person books (Stay22; Stay Cost Brain may earn a commission)

Towns that haven't been researched return researched: false and no figure: nothing is estimated and presented as fact.

Example questions

  • "How much hotel tax will I pay in New York City for 2 nights if the room costs $600 in total?"
  • "What is the tourist tax for 3 nights in a 4-star hotel in Barcelona for 2 adults?"
  • "Do children pay the tourist tax in Lisbon?"
  • "Who is exempt from the tourist tax in Venice?"
  • "Find hotels in Lisbon for 20 to 23 November for 2 adults."
