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

Create a secure cancellation handoff for a hotel reservation. After verifying the guest, this tool returns the hotel cancellation policy on file and a first-party 1Stay cancellation URL. It never cancels the reservation in conversation. The guest must open the secure page, review the policy, and explicitly confirm there. 1Stay does not estimate a refund, credit, penalty, or amount the hotel may charge. Until that page reports success, the reservation is NOT cancelled. A successful cancellation is confirmed on the page and by email to the address on file.

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. Non-refundable rates are cheaper but cannot be changed or canceled.

hotels

search_hotels

Search hotels by location and dates for exactly one room, with check-in up to 340 days from today. 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 last 4 digits of the card used to book together with the check-in date. An email address is not a verification factor. It may be supplied in addition and will be matched, but a name and an email alone will not return a reservation.

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 287 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 with the file path 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 287 ms on average, which is faster than 52% 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 3 open issues, but we could not determine the licence, and without one the code is not open source by default.
