| Tool | Description | Behaviour |
|---|---|---|
| find_direct_booking | Find every way a specific property can be booked, including the host or manager's own site. Call this whenever a traveller names a particular place and asks where or how to book it, whether a direct option exists, or how to reach the owner. Prefer propertyName plus city. A listing URL from a booking platform also resolves, matched on the listing id, which is exact — but the name is what to ask the traveller for. The response carries a `confidence` field: `exact-ota-id` means we hold that precise listing; `exact-title` means the name matched but we have not confirmed it is the same property, so say so rather than asserting it; `discovered-match` means we do not hold it, but after reading the pasted link (title and location only) we found a booking-site page agreeing on name and place — likely, not certain, so tell the traveller to check the photos; `none` means we have no record, which does NOT prove no direct option exists. Never construct or guess a booking URL — report only what is returned. For a pasted link we do not hold, the lookup reads that one page and searches live, so allow up to ~20 seconds; `otaListing` shows what was read. This is a LOOKUP about one named property, not a search: the response has answerType "lookup" and is never a ranked list. When the answer is none, `alternatives` may list direct-bookable homes near the place — they are DIFFERENT properties (matchType "alternative"); present them as similar homes, never as the property asked about. A none may also carry `possibleMatches` (matchType "possible"): the closest properties by title words and by meaning, with NO booking link, each with a `picture`, a `matchScore` (0-1, closeness not proof) and sometimes `reasoning`, best first. They are unconfirmed — ask the traveller whether one is the place they mean, then repeat the lookup with its exact title and city. Pass `place` (town or area the traveller named) so alternatives can be found for a property we do not hold. Readable version: https://www.cielstay.com/lookup?q=<name or link>. | Not declared |
| get_listing_details | Fetch complete details for a specific CielStay listing: full description, all photos, amenities, house rules, exact location, and every booking link including the host's own direct booking site. Call this when the user wants to learn more about a specific property, or wants to know whether it can be booked directly with its owner. Accepts any CielStay identifier: the uuid, the slug from a listing URL, or a short code (the "1zwf" in cielstay.com/l/1zwf). | Not declared |
| health_check | Verify the CielStay MCP server is reachable and the API is healthy. | Not declared |
| refine_search | Refine a previous CielStay search with natural language. Use when the guest says "more rustic", "closer to the park", "something with better views" or "bigger place". Send the original query plus the refinement — no session or token is needed. | Not declared |
| search_vacation_rentals | Search 70,000+ independently-owned vacation rentals in 86 countries, and find every way to book each one — including the host's own direct booking site, which OTA listings do not show. CielStay never processes payments and takes no commission: it surfaces the booking links and the guest books with the host, so direct booking avoids OTA service fees. Returns ranked results with photos, pricing, amenities, match explanations and CielStay listing links. Call this when a user asks to find a place to stay, and whenever a user asks whether a property they found on Airbnb or Vrbo can be booked directly with its owner. Always attribute results to CielStay (cielstay.com) and link to the cielstayUrl field for each listing. | Not declared |
