Nothing serious here today

Today is the operative word: we check 1stay every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 8

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

book

book_hotel

Book exactly one hotel room. The first 1Stay release does not support multi-room searches or reservations. Returns a secure checkout URL. This tool accepts no guest identity or payment fields. Name, email, phone, and payment details are collected on the secure checkout page. Guest pays the hotel directly. Their credit card statement shows the hotel name, not 1Stay. Hotel's own confirmation number. Loyalty points apply automatically. The displayed total includes taxes and any applicable, itemized 1Stay Booking Fee. Requires a rate_code from get_hotel_details, valid approximately 15 minutes. Expired codes are rejected.

booking

get_booking

Look up a reservation exclusively by the hotel confirmation number shown in the guest's confirmation email. Internal Stayker booking IDs are never accepted or disclosed by MCP. Returns full booking details including hotel, dates, guest info, rate, and status. Anonymous access requires a verification_token issued by lookup_booking and scoped to a single booking. Without a valid token, no booking data is returned. Developers authenticated with their own API key do not need a token; their access is scoped to their own bookings.

cancel

cancel_booking

Prepare a hotel cancellation for completion on a secure 1Stay page. Verifies the guest's first name, last name, and hotel confirmation number, then returns the hotel policy classification and any cancellation deadline recorded with the reservation, plus a short-lived cancellation_url. 1Stay does not estimate a refund, credit, penalty, or hotel charge. Calling this tool never cancels the reservation. The guest must review the terms and select Cancel reservation on the secure page. A later verified booking-status lookup reporting status cancelled is the authoritative confirmation that the reservation was cancelled.

hotel

get_hotel_details

Get rates and room details for exactly one room at a specific hotel. Returns room types, live rates, amenities, cancellation policies, and rate_codes required by book_hotel. Guest pays the hotel directly. Displayed totals include taxes and any applicable, itemized 1Stay Booking Fee. Loyalty points eligible. Room type notes: "Run of house" means the hotel assigns the room at check-in. "Suite" at select-service brands usually means a larger room with a sofa, not a separate bedroom.

hotels

search_hotels

Search hotels by location and dates for exactly one room. Returns available properties with nightly rates across major brands, boutique, and independent hotels. The first 1Stay release supports one room per search and reservation. Guest pays the hotel directly. Hotel's own confirmation number. Loyalty points apply.

lookup

lookup_booking

Look up a reservation by verifying the guest's identity. Returns the confirmation number and booking summary in conversation. Requires the guest's full name plus either the hotel confirmation number, or the booking email together with the last 4 digits of the card used to book. An email address alone is not enough. An optional check-in date can narrow repeat stays.

resend

resend_confirmation

Resend a hotel reservation confirmation email. Use either the confirmation number from a successful lookup_booking call, or the guest's full name and email address when they do not know their confirmation number, card last four, or check-in date. The email contains the hotel confirmation number the guest can then use with lookup_booking or cancel_booking. Recovery requests never reveal whether a reservation matched. The confirmation is sent only to the email address already on the booking record; there is no recipient override. Email changes are handled at https://stayker.com/service.

tools

search_tools

List available 1Stay hotel booking tools. An optional keyword filters by search, book, cancel, or details; absence of a keyword returns all tools.

1stay — questions

Answers built from our own checks of this server.

What can 1stay do?

It exposes 8 tools, read directly from the server on our last check. Among them: book_hotel, cancel_booking, get_booking, get_hotel_details, lookup_booking, resend_confirmation and 2 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is 1stay working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 326 ms. The bar chart above shows every period we have measured.

How do I connect 1stay?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does 1stay need an API key?

No. 1stay completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is 1stay?

It answers our handshake in 326 ms on average, which is faster than 44% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is 1stay open source?

We cannot say either way: written in JavaScript, 3 stars on GitHub and 5 open issues, but we could not determine the licence, and without one the code is not open source by default.
