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.

watch
watch_booking
For a stay already booked with free cancellation: pass the confirmation email's text. The otter keeps five facts (property, dates, total paid, deadline, where it was booked), discards the rest (no names, confirmation numbers or card details), reads the property's rate every morning and emails the account when a cheaper rate it can still cancel into appears (5% or $50), with reminders 7, 3 and 1 days before the deadline. Hotels booked direct are read across sellers through Google's rate list. A single whole home has one calendar, so once booked its price can't drop for the traveller: the first read finds the nights taken, the otter emails to say so and offers (free) to watch other whole homes nearby for the same dates until the deadline. Needs a key; free and unlimited. The otter never books or cancels.
watch_similar_homes
For a whole home already booked (watch_booking, then the first morning's read found the nights taken by the traveller): watches other verified whole homes nearby for the same dates and party, and emails the account when one comes in at least 5% or $50 under what they paid, until their free-cancellation deadline. A find is always a different home, never the same one cheaper; the traveller books the new one first and cancels theirs second. Starts with one live search now (30 to 90 seconds; not counted as a trip). Needs the key the booking was watched with; free.
activities
get_activities
Top-rated things to do on Viator for a search's spot and dates (what the trip is for first, the city's best otherwise), with a second place to look when the row is thin. Pass a searchId from search_stays or city_picks; intent overrides the search's own.
alert
set_alert
Starts the otter's daily re-run of a finished search, emailing the key's account when a verified pick drops 5% or $50 or the cheapest pick disappears. Needs a key (stayotter.com/connect); the first alert is free with an account, more are Pro.
city
city_picks
Instant and free: the latest finished standard search for one of the covered cities, about six weeks out, refreshed on a rota: whole homes for two adults and five nights in most cities, a six-adult weekend in Nashville, Scottsdale, New Orleans, Miami, Las Vegas; stayType "hotel" gives the hotel-room trip (two adults, three nights) where one exists (Austin, Lisbon, Kyoto, Mexico City, New York, Paris, Barcelona, Montreal, San Diego, Edinburgh, Honolulu, London, Nashville, Scottsdale, New Orleans, Miami, Las Vegas). Covered: Austin, Lisbon, Kyoto, Mexico City, New York, Paris, Barcelona, Montreal, San Diego, Edinburgh, Honolulu, London, Nashville, Scottsdale, New Orleans, Miami, Las Vegas, South Lake Tahoe, Sedona, Holbox, Niagara-on-the-Lake, Bentonville, Knoxville, Asheville, Canmore, Coeur d'Alene, Broken Bow, Lancaster, Ann Arbor, Da Nang, Hoi An. For other places or specific dates use search_stays.
listing
check_listing
Reads one place the traveller found themselves into the receipts a pick carries: where it is, whether the street is quiet or lively, bars, cafés and restaurants within a ten-minute walk, the distance to a spot they name and, with dates, the lowest total and the lowest they can still cancel, each read now. Takes a Booking.com, Vrbo or Expedia property page, or a hotel's name and city; Airbnb pages cannot be read. Needs a key: one check a day free, Pro up to thirty. 5 to 60 seconds.
stay
get_stay
The card for a search by searchId: finished picks with receipts, or its running status. Free and instant. Use it to finish a search_stays call that returned 'running', or to read a shared stay (https://stayotter.com/stay/s_…).
stays
search_stays
Live search of Booking.com, Vrbo and Expedia (hotel rooms) for the dates and party, verified against the map. Returns up to three picks (best overall, best value, closest) with receipts and tracked openUrl links. Takes 30 to 90 seconds; returns status 'running' with a searchId if it is not done within waitSeconds. Three searches on the house per connection, then a key (free account: 10 a month; Pro: unlimited).

Stay Otter — questions

Answers built from our own checks of this server.

What can Stay Otter do?
It exposes 8 tools, read directly from the server on our last check. Among them: check_listing, city_picks, get_activities, get_stay, search_stays, set_alert 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 Stay Otter working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 128 ms. The bar chart above shows every period we have measured.
The registry lists Stay Otter as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Stay Otter?
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 Stay Otter need an API key?
No. Stay Otter 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.
