What it can do
Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.
list_hotelsSearch hotel properties in Germany, Austria, Switzerland, the United Kingdom and the United States, and price them for a stay in the same call. ASK BEFORE YOU SEARCH. Four things are required and this tool answers nothing without them: `checkIn`, `checkOut`, `adults` and `maxPric
hotel_reserveBook a hotel room. Works for ANY offer `list_hotels` gave you an `offerId` for — there is no separate check to make first, so pass the offer the guest chose. Pass that offer’s `offerId` exactly as you were given it — it names the hotel, room, rate, stay and price, which is why no

Common questions
Is Bluerails Hotels safe?
It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.0) reached the registry yesterday.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Context7, Codebase Memory, Exa
