## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-06.

- **Endpoint Security**: 46/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not yet verified: we couldn't confirm whether this endpoint requires it.
  - HTTPS enforcement could not be verified: the plaintext port redirected somewhere other than https, so enforcement is unproven.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 0/100
  - Transport check failed: declared streamable-http, but the endpoint redirected instead of responding directly.
- **Schema Quality & AI Usability**: 0/100
  - Schema not yet verified: we couldn't read the endpoint's schema, or could read only part of its tool list.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 0/100
  - Tool coverage not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.
- **Tool Safety**: 0/100
  - Tool safety not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.
- **Capabilities**: 0/100
  - Capabilities not yet verified: we couldn't read the endpoint's capabilities.

**Unverified: 5 categories.** Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

POST /kp/inventory/fetch_rooms_availability.

Input parameters:

- `arrival` (string, required): Arrival date, yyyy-mm-dd.
- `departure` (string, required): Departure date, yyyy-mm-dd.

### `wubook_get_rate_values` (~121 tokens)

### `wubook_update_inventory` (~221 tokens)

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.

Input parameters:

- `from` (string, required): First day the lists start at, yyyy-mm-dd.
- `products` (object, required): Product id → one object per day, e.g. {"12": [{"p": 90, "a": 3}, {"p": 95}]}. Keys: p price, a availability, m/M min/max stay, ma/Ma by arrival, ni no check-in, no no check-out, c closed, nt no OTA,…

- `created_from` (string): Created on or after (yyyy-mm-dd). Needs created_to.
- `created_to` (string): Created on or before.
- `departure_from` (string): Departing on or after. Needs departure_to.
- `departure_to` (string): Departing on or before.
- `limit`: Page size: 8, 16, 32 or 64 (default 32).
- `offset` (integer): Reservations to skip (default 0). Pass the previous reply's next_offset.

### `wubook_list_todays_reservations` (~45 tokens)

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` (~185 tokens)

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.

Input parameters:

- `arrival` (string, required): Arrival date, yyyy-mm-dd.
- `assign_rooms` (boolean): Let ZaK choose physical rooms for entries without a room id.

- `rooms` (array)

Input parameters:

- `reservation_code` (string): Reservation (human) code such as XY-0001.
- `reservation_id` (integer): Reservation id.
- `room_customer_ids` (array): Only these reservation-room guest ids (default: all guests).

### `wubook_check_out` (~96 tokens)

- `reservation_id` (integer): Reservation id.

### `wubook_undo_check_out` (~65 tokens)

- `reservation_id` (integer): Reservation id.

### `wubook_get_customer` (~100 tokens)

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.

Input parameters:

- `customer_id` (integer, required): Customer id.
- `include_documents` (boolean): Also return the guest's identity documents (default false).

## Common questions

### What is the WuBook MCP by usefulapi server?

WuBook MCP by usefulapi is listed in the public MCP registry as io.usefulapi/wubook. Read WuBook ZaK rooms, availability and reservations; manage inventory and guest check-in. This page covers its hosted endpoint (https://wubook.usefulapi.io/mcp).

### Is the WuBook MCP by usefulapi server safe to use?

WuBook MCP by usefulapi scores 18 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the WuBook MCP by usefulapi server expose?

WuBook MCP by usefulapi exposes 19 tools: wubook_list_rooms, wubook_list_room_types, wubook_list_rates, wubook_list_products, wubook_list_meal_boards, and 14 more. Their descriptions and schemas cost roughly 1,730 tokens of context every time the server is loaded.

### Does the WuBook MCP by usefulapi server require authentication?

Its publisher declares no required credentials for WuBook MCP by usefulapi. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.

### Is the WuBook MCP by usefulapi server still maintained?

WuBook MCP by usefulapi is still listed as active in the MCP registry. We last reached this channel on 6 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the WuBook MCP by usefulapi server?

VerifyMCP ran 4 checks on WuBook MCP by usefulapi, covering TLS certificate, HSTS header, DNSSEC and Transport. 7 items could not be completed, a gap on our side rather than a finding about WuBook MCP by usefulapi: Authorization, HTTPS, Schema quality, Stability and 3 more. 5 categories score 0 for that reason, because we only credit what we can confirm. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
