Stay Cost Brain
com.staycostbrainPublished by staycostbrain.comOfficial publisherv1.0.0Updated Oct 29, 2026
Tourist and hotel taxes from official sources, worked out night by night for your dates and guests.
Overview
AI-generated overview
Remote MCP server that looks up sourced tourist and city taxes for a stay and computes them night by night for given dates and guests.
- What you can do
- Describe coverage, sourcing and limits of the tax data
- List researched places with headline rates, check dates and towns with their own tax
- Compute the tourist tax for one stay night by night, with each regional and city part, ranges, night caps and announced changes
- Retrieve every tax rule for a place: rates by stay type, seasons, exemptions, status and sources
- Return a link to live hotel and rental prices for the dates and guests
- When to use it
- Useful when someone wants to know what a stay really costs beyond the room price, or asks about tourist tax rates, exemptions for children, or who pays in a given city. It also helps when comparing destinations or explaining how a tax is charged at the hotel.
- Requirements
- Remote streamable HTTP endpoint at staycostbrain.com; no API key, login or account. Any MCP client that supports HTTP transport, plus network access. Rate limit of 30 requests per 10 seconds per IP.
Before you install
Read-only and free, but it returns no room prices and books nothing; the hotel link goes to a third-party service where the person sees prices and books, and the operator may earn a commission. Only the tool arguments (place, dates, party size, room price) are sent. Places not yet researched return researched=false rather than an estimate.
Installation
In SourceWeft
- Open Stay Cost Brain in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/com.staycostbrain%2Fstay-cost-brain/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Other MCP clients
Add this to your client's mcpServers config.

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):

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
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."

tourist_tax
Tourist tax
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.

Score
100% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
