Read WuBook ZaK rooms, availability and reservations; manage inventory and guest check-in. Hosted by usefulapi: connect it to Claude, ChatGPT, Cursor or any MCP client.
Turn on the WuBook connector, then ask in plain words. The AI picks the tools.
For hospitality teams that manage rooms, rates and reservations in WuBook ZaK.
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.
The AI lists today’s reservations and opens a selected booking to review its dates, rooms, occupancy, charges and recorded payment.
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.
Changes dataAfter 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.
Changes dataThe 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.
Team and Enterprise: an Owner adds the connector for the organization first.
No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
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": {
"wubook": {
"type": "http",
"url": "https://wubook.usefulapi.io/mcp"
}
}
} Run these commands. The second one opens the login page:
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 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.
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper API key | $9/mo · $90/yr | 10,000 tool calls / month |
| Pro+per API key | $39/mo · $390/yr | 100,000 tool calls / month |
Each paid plan covers this WuBook server only. Ask your AI to run wubook_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 wubook_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 wubook_upgrade before then undoes the cancel. Or write to [email protected].

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 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this WuBook server only. Cancel any time: your paid plan 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 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 wubook_cancel_subscription. Your paid plan 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.
