Read WuBook ZaK rooms, availability and reservations; manage inventory and guest check-in. For hospitality teams that manage rooms, rates and reservations in WuBook ZaK. Hosted by usefulapi — connect from Claude, ChatGPT, Cursor, or any MCP client.
Team and Enterprise: an Owner adds the connector for the organization first.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"wubook": {
"url": "https://wubook.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {

"url": "https://wubook.usefulapi.io/mcp"
}
}
}No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run these commands. The second one opens the login page:
Other MCP clients (Windsurf, Cline, Zed and more): add the URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser. Do not add an Authorization header: see Before you connect.
The AI checks room availability for a stay and reads rate values for the relevant dates. Bookable capacity comes from the availability count, which can differ from the number of listed physical rooms.
wubook_get_room_availability wubook_list_rates wubook_get_rate_values
The AI lists today’s reservations and opens a selected booking to review its dates, rooms, occupancy, charges and recorded payment.
wubook_list_todays_reservations wubook_get_reservation
The AI reads current rate values and updates the daily prices, availability or restrictions you specify. Changes can affect live bookings and connected channels, so confirm the values first.

After reviewing a booking, the AI can check its guests in or out when requested. You can apply the action to all guests or select reservation-room guest IDs.

The login page asks for your WuBook ZaK API key.
In ZaK open Settings → Configurations → ZaK API and generate the key (it starts with wb_). The ZaK API needs the Essentials Module and must be switched on by WuBook staff first. If you set an IP allow-list on the key, leave it empty or calls from this server are refused. Your key is used only to call the WuBook API on your behalf; it is never shown to anyone.
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 WuBook ZaK API key. 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.
Turn on the WuBook connector, then ask in plain words. The AI picks the tools.
| Tool | Type | What it does |
|---|---|---|
wubook_list_rooms | read | List rooms List the physical rooms of the property (id, room type id, name, tags). POST /kp/property/fetch_rooms. |
wubook_list_room_types | read | List room types List the room types (id, name, short name, default price, default occupancy). POST /kp/property/fetch_room_types. |
wubook_list_rates | read | List rates List the rates of the property (id, name, board, currency, standard flag). Use a rate id for prices and restrictions. POST /kp/property/fetch_rates. |
wubook_list_products | read | List products List the products (a room type sold on a board basis: id, room type id, name, default price, occupancy). Product ids are the keys of prices and availability. POST /kp/property/fetch_products. |
wubook_list_meal_boards | read | List meal boards List the meal rules and meal prices per board type (fb, hb, bb, ai) for adults, teens, children and babies. POST /kp/property/fetch_meals_board. |
wubook_list_extras | read | List extras List the extras the property sells (id, name, price, VAT percentage, cost, tags). POST /kp/property/fetch_extras. |
wubook_get_inventory_symbols | read | Get inventory symbols The meaning of the short keys in prices and restrictions (p price, a availability, m MinStay, M MaxStay, c closure, ...). POST /kp/inventory/fetch_symbols. |
wubook_get_room_availability | read | Get room availability Availability for a stay: for each room type id, the number of rooms available and the ids of the available physical rooms. The availability count can be lower than the number of listed physical rooms when a reservation has no physical room assigned yet; use the availability count when assessing bookable capacity. POST /kp/inventory/fetch_rooms_availability. |
wubook_get_rate_values | read | Get rate values Daily prices, availability and restrictions of one rate, starting at a date: for each product id a list with one object per day (p price, a availability, m/M min/max stay, c closed, ...; see wubook_get_inventory_symbols). POST /kp/inventory/fetch_rate_values. |
wubook_update_inventory | write | Update prices, availability and restrictions WRITE: overwrite daily prices, availability and stay restrictions of one rate. `products` maps a product id to a list of day objects; the first object is the day `from`, the next the following day, and so on. Only the fields you send per day change. Changes can be pushed to connected channels (OTAs) and affect live bookings, so confirm the values with the user first. POST /kp/inventory/write. |
wubook_get_reservation | read | Get reservation One reservation by id or by reservation code (XY-0001): status, booker customer id, origin channel, board, dates, price split (rooms, extras, meals), payment, taxes and rooms with occupancy and customer ids. POST /kp/reservations/fetch_one_reservation. |
wubook_list_reservations | read | List reservations List reservations, optionally filtered by creation, arrival or departure date ranges (inclusive). Newest first is not guaranteed; page with offset. Returns the page plus next_offset (null when the last page was reached). POST /kp/reservations/fetch_reservations. |
wubook_list_todays_reservations | read | List today's reservations Reservations of the property for today (arrivals, departures and stays in house). POST /kp/reservations/fetch_today_reservations. |
wubook_create_reservation | write | Create reservation WRITE: create a reservation in ZaK for one guest. Give rooms (room type and optionally the physical room id, with price and currency) and/or products (product id with price and currency). Set assign_rooms to let ZaK pick the physical rooms. This books inventory and is NOT idempotent: calling it twice creates two reservations, so check wubook_get_room_availability first and do not retry on an error without looking the reservation up. POST /kp/reservations/new. |
wubook_check_in | write | Check in WRITE: check in the guests of a reservation in ZaK. Applies to every guest of the reservation unless room_customer_ids is given. POST /kp/reservations/do_checkin. |
wubook_check_out | write | Check out WRITE: check out the guests of a reservation in ZaK. Applies to every guest of the reservation unless room_customer_ids is given. POST /kp/reservations/do_checkout. |
wubook_undo_check_in | write | Undo check-in WRITE: revert the check-in of a reservation in ZaK. POST /kp/reservations/undo_checkin. |
wubook_undo_check_out | write | Undo check-out WRITE: revert the check-out of a reservation in ZaK. POST /kp/reservations/undo_checkout. |
wubook_get_customer | read | Get customer (guest) One guest record by customer id (from a reservation's booker or room customers): name, country, address, contact, birth data, billing info. Personal data. Identity documents (type, number, expiry) are left out unless include_documents is true. POST /kp/customers/fetch_one. |
wubook_usage_status | Usage status (free-tier meter) Report 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. | |
wubook_request_feature | Request a missing feature Tell usefulapi that the user needs something the WuBook 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. | |
wubook_upgrade | Upgrade to Pro (unlimited*) Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on WuBook (the free tier caps monthly usage). Plans: "monthly" — $9/month; "yearly" — $90/year (2 months free). Cancel any time: Pro then runs to the end of the paid period, so it also suits a one-time job. *A fair use limit applies. For heavy use (near Pro's limit): "plus" or "plus_yearly" — Pro+, $39/month or $390/year, unlimited tool calls (fair use limit: 100,000 a month); an existing Pro subscription changes to Pro+ in place (needs confirm: true; the price difference for the rest of the period is charged at once). Otherwise returns a short link to open in your browser (it opens Stripe Checkout); after payment the account upgrades automatically. Does not count against the meter. | |
wubook_cancel_subscription | Cancel the Pro subscription Cancel the caller's WuBook 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 wubook_upgrade later to undo the cancel before the period ends. Does not count against the meter. |
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper API key | $9/mo · $90/yr | Unlimited* |
*Pro fair use limit: 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this WuBook server only. Subscribe with wubook_upgrade (it returns a Stripe Checkout link). Cancel any time with wubook_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running wubook_upgrade before then undoes the cancel. Or write to [email protected].
Check availability before taking a booking. Review arrivals and reservation details. Change prices or close dates for sale. Check guests in or out. See what you can do for the details.
No. usefulapi is an independent service. It is not affiliated with or endorsed by WuBook. The server calls the WuBook API with your own WuBook access, so it sees only the data that your account can see.
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.
The login page asks for your WuBook ZaK API key. See Before you connect for where to find it.
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 WuBook ZaK API key. 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.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the WuBook 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 WuBook.
Yes, if you approve it. 6 of the 19 WuBook tools can create or change data. The other 13 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls (fair use limit: 10,000 tool calls a month), for this WuBook server only. Cancel any time: Pro then runs to the end of the paid period. Run wubook_usage_status to see how many calls you used.
Ask the AI to run wubook_upgrade: it returns a Stripe Checkout link. To cancel, run wubook_cancel_subscription. Pro continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with wubook_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.
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.
