    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.

    search_vacation_rentalsSearch about 70,000 vacation rentals and longer-stay homes from independent hosts and property managers in 70+ countries and territories. Each result lists the ways it can be booked that CielStay holds: the host's own booking site or engine (directUrl / referenceUrl) and a CielStay listing page (cielstayUrl). CielStay does not take bookings or payments. Results are ranked by fit to the request, with a photo, nightly rate, match score and match reason. Suited to finding a place to stay, or to checking whether a home seen on another site can be booked with its host.
    refine_searchRefine a previous CielStay search in natural language, such as "more rustic", "closer to the park", "better views" or "bigger place". Takes the original query plus the refinement; no session or token is needed.
    get_listing_detailsFull details for one CielStay listing: description, photos, amenities, house rules, location, and every booking link CielStay holds, including the host's own booking site. With checkIn and checkOut, the response also carries liveQuote where the host's booking engine supports it: the total on the host's own site for those dates (room, fees and taxes), read live. Each live quote is a real request to the host's booking engine. Accepts the listing id, the slug from a listing URL, or a short code (the "1zwf" in cielstay.com/l/1zwf).
    get_propertyEvery unit at one multi-unit property: a hotel, glamping site or building whose units share a booking site and a location. Search results carry readyToBook.property.id when a home is one of several such units. Returns the property (name only where the operator's own unit titles share it), and each unit with its label, bedrooms, guests, CielStay page and readyToBook. With checkIn and checkOut, each unit's readyToBook also carries availability and the total on the host's site for those dates (up to 30 units).
    find_direct_bookingLook up one named property and every way it can be booked, including the host's or manager's own site. Takes propertyName plus city (most reliable), or a listing URL from a booking platform, which is matched on its listing id. The response has answerType "lookup": a lookup about one property, not a ranked search. `confidence` describes the match: `exact-ota-id`, CielStay holds that exact listing; `exact-title`, the name matched but it is not confirmed to be the same property; `discovered-match`, CielStay does not hold it, but after reading the pasted link (title and location only) it found a booking-site page that agrees on name and place, which is likely but not certain; `none`, CielStay has no record, which does not show that no direct option exists. Every booking URL in the response is one CielStay holds or found; none is constructed. For a pasted link CielStay does not hold, the lookup reads that one page and searches live (up to about 20 seconds); `otaListing` shows what was read. When the answer is none, `alternatives` lists different, direct-bookable homes near `place` (matchType "alternative"), and `possibleMatches` lists the closest unconfirmed candidates by name and meaning (matchType "possible", no booking link, `matchScore` 0-1 is closeness, not proof). Readable version: https://www.cielstay.com/lookup?q=<name or link>.
