usefulapiSmoobu MCP server
Check vacation-rental reservations, rates, availability and guest messages, and update bookings. Hosted by usefulapi: connect it to Claude, ChatGPT, Cursor or any MCP client.
What can I ask?
Turn on the Smoobu connector, then ask in plain words. The AI picks the tools.
- Which guests arrive over the next 7 days, and at which properties?
- Which of my properties are free from August 3 to August 8, and at what price?
- Show me the latest guest messages across my bookings.
- Show the check-in time on Jane Smith's booking for Friday.
What you can do with Smoobu in Claude and ChatGPT
For vacation rental hosts who manage reservations, rates and guest messages in Smoobu.
See who arrives soon and where
The AI lists reservations across channels filtered by arrival date or property. It shows guest, dates, channel, price and payment status.
Find open properties for dates and quote the price
The AI checks which properties can be booked between an arrival and a departure date, with the total price. It tells why others are not available.
Read guest conversations and draft a reply
The AI reads the inbox threads and the full conversation of a reservation. It can also read the placeholder values such as dates and check-in link to prepare a message.
Break down a reservation's price
The AI lists the price elements of a reservation: base price, cleaning fee, add-ons, discounts and coupons with amounts and tax.
Set rates, create or update bookings, or message guests
The AI sets nightly prices and minimum stays, creates or updates a reservation, or sends a message to a guest. Rate changes reach channels with price sync on.
Changes dataHow do I connect Smoobu?
Before you connect
The login page asks for your Smoobu API key and Smoobu API secret.
Create both in Smoobu → Settings → Advanced → API Keys. Enable Guest Data (PII) on that key if you want guest names and contact details; Smoobu returns empty personal-data fields without it. Message bodies may be HTML-only. The secret is shown only once, when the key is created. Both are required for HMAC-signed requests. Your credentials are used only to call the Smoobu API on your behalf and to derive a private account id; they are never shown to anyone.

Claude Code
Run this command, then run /mcp in Claude Code to log in:
Cursor
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"smoobu": {
"url": "https://smoobu.usefulapi.io/mcp"
}
}
} VS Code
Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"smoobu": {
"type": "http",
"url": "https://smoobu.usefulapi.io/mcp"
}
}
} Codex
Run these commands. The second one opens the login page:
Other clients
Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.
Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Smoobu API key and Smoobu API secret. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
Pricing
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper user | $9/mo · $90/yr | 10,000 tool calls / month |
| Pro+per user | $39/mo · $390/yr | 100,000 tool calls / month |
Each paid plan covers this Smoobu server only. Ask your AI to run smoobu_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with smoobu_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with smoobu_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Read only · 16
- Get the current user
smoobu_get_userFetch the Smoobu user these credentials belong to (id, name, email). A cheap way to confirm the setup works; the id is the customerId used by availability checks. - List properties
smoobu_list_apartmentsList every property (Smoobu calls them apartments) in the account, with id and name. Start here to get apartment ids. - Get one property
smoobu_get_apartmentFetch one property's details: location, time zone, rooms and beds, max occupancy, amenities, currency, min/max nightly price and type. - List reservations
smoobu_list_reservationsList reservations across all channels (Airbnb, Booking.com, direct, ...), paginated, with guest, dates, channel, price and payment status. Filter by stay range, arrival, departure, creation or modification date, and property. - Get one reservation
smoobu_get_reservationFetch one reservation by id: guest, dates, check-in/out times, channel and its reference id, price, prepayment and deposit status, and the guest-app URL. - List a reservation's price elements
smoobu_list_price_elementsList the financial breakdown of one reservation: base price, cleaning fee, add-ons, long-stay discounts and coupons, with amounts, tax and currency. - Get a reservation's message placeholders
smoobu_get_reservation_placeholdersGet every placeholder value Smoobu would substitute into a message for this reservation: guest name, dates and times, nights, price and balance, online check-in link, guest-app link, door PIN codes and more. Useful for drafting a guest message. - Get rates and availability
smoobu_get_ratesGet the nightly price, minimum length of stay and availability (0 = not available) for each date in a range, for one or more properties. - Check availability and quote a stay
smoobu_check_availabilityCheck which properties can be booked for an arrival/departure pair and get the total price for each; unavailable ones come back with the reason (minimum stay, too many guests, arrival day, lead time...). Read-only, books nothing. - List inbox threads
smoobu_list_message_threadsList the unified guest inbox: booking.guest_name, latest_message.subject, latest_message.text_content and latest_message.html_content, plus property and unread count. Read HTML when plain text is empty. Guest names require Guest Data (PII) enabled for the key; missing upstream content is not reconstructed. - Read a booking conversation
smoobu_get_conversationRead one reservation and one page of its actual messages directly, rather than relying on an inbox thread's latest-message summary. Returns the guest name from the reservation and unmodified message subject, plain-text and HTML fields with pagination. If the reservation name is blank and it identifies a guest, also checks that guest's documented profile for a name. Uses only this connection's permissions; does not reconstruct missing content or change the key's PII access. At most three read requests. An empty body remains explicitly unresolved; a successful HTTP response is not evidence that content is present. - List a reservation's messages
smoobu_list_reservation_messagesGet a reservation's conversation, paginated, preserving subject, message (plain text), messageHtml/htmlMessage (HTML), and type (1 = inbox / from guest, 2 = outbox / sent). Read HTML when message is empty. Guest names are on smoobu_get_reservation (guest-name) or smoobu_list_message_threads (booking.guest_name), not this endpoint; Guest Data (PII) must be enabled for the key. Missing upstream content is not reconstructed. - List guests
smoobu_list_guestsList guests from the Smoobu CRM with their emails, phone numbers, address, notes and bookings; optionally search. - Get one guest
smoobu_get_guestFetch one guest by id (the guestId on a reservation) with contact details, notes and every booking they have made. - List add-ons
smoobu_list_addonsList the bookable add-ons (towels, breakfast, late check-out...) with amount, tax, calculation type (0 per booking, 1 per person, 2 per night, 3 per person and night) and the properties they apply to; optionally for one property. - List custom placeholders
smoobu_list_custom_placeholdersList the account's custom message placeholders (key, default value, and whether they are global, per booking or per property).

- Create a reservation
smoobu_create_reservationCreate a reservation (or a blocked period) on a property. Smoobu treats it like a booking from a channel and SYNCS the blocked dates to every connected channel (Airbnb, Booking.com, ...). Fails if the dates overlap an existing booking. This server offers no cancel — cancel it in Smoobu if needed. Which guest fields are mandatory depends on your booking-tool 'Form Content' settings. - Update a reservation
smoobu_update_reservationUpdate an existing reservation's times, guest contact, notes, guest counts, language, or price / prepayment / deposit amounts and paid status. Only the fields you pass are sent. Dates and property cannot be changed here. - Set rates and minimum stays
smoobu_set_ratesSet the nightly price and/or minimum length of stay for dates on one or more properties. Smoobu PUSHES these to every channel with price sync enabled, so this changes live prices guests see. Reversible by setting the old values again — read them first with smoobu_get_rates. Each operation needs daily_price, min_length_of_stay, or both (a minimum stay alone needs an existing price). - Send a message to a guest
smoobu_send_message_to_guestSend a message to the guest of a reservation through Smoobu (it goes out on the booking's channel, e.g. the Airbnb or Booking.com inbox, or email). Delivered IMMEDIATELY and cannot be unsent — confirm the text with the user first. - Post a message to the host
smoobu_send_message_to_hostPost a message on a reservation's thread addressed to the Smoobu user (the host). With internal=true it is an internal note hidden from the guest — handy for logging. Cannot be unsent.
Your usefulapi plan · 4
- Usage status (free-tier meter)
smoobu_usage_statusReport the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter. - Request a missing feature
smoobu_request_featureTell usefulapi that the user needs something the Smoobu tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter. - Upgrade to Pro or Pro+
smoobu_upgradeGet a paid plan for Smoobu (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter. - Cancel the Pro subscription
smoobu_cancel_subscriptionCancel the caller's Smoobu Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run smoobu_upgrade later to undo the cancel before the period ends. Does not count against the meter.
FAQ
What can I do with Smoobu in Claude or ChatGPT?
See who arrives soon and where. Find open properties for dates and quote the price. Read guest conversations and draft a reply. Break down a reservation's price. Set rates, create or update bookings, or message guests. See what you can do for the details.
Is this an official Smoobu product?
No. usefulapi is an independent service. It is not affiliated with or endorsed by Smoobu. The server calls the Smoobu API with your own Smoobu access, so it sees only the data that your account can see.
Can I connect Smoobu to Claude or ChatGPT?
Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.
What do I need to connect?
The login page asks for your Smoobu API key and Smoobu API secret. See Before you connect for where to find them.
Do I put my Smoobu key or an Authorization header in the client config?
No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Smoobu API key and Smoobu API secret. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
How do you keep my Smoobu credentials?
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Smoobu API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in Smoobu.
Can the AI change my Smoobu data?
Yes, if you approve it. 5 of the 21 Smoobu tools can create or change data. The other 16 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
What does it cost?
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this Smoobu server only. Cancel any time: your paid plan then runs to the end of the paid period. Run smoobu_usage_status to see how many calls you used.
How do I subscribe or cancel?
Ask the AI to run smoobu_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run smoobu_cancel_subscription. Your paid plan continues to the end of the paid period.
What if a Smoobu tool that I need is missing?
Tell the AI what you wanted to do. It can send the request with smoobu_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.
Which AI clients can I use?
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.
This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
