## Findings

```untrusted-server-text
The description mentions "credentials".

```


## Deletes or cancels (5)

Removes, cancels or revokes something. Claude Code: deny.

### `smoobu_create_reservation`

- The name "smoobu_create_reservation" says "create": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Create 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. Smoobu: POST /api/reservations.
```

### `smoobu_send_message_to_guest`

- The name "smoobu_send_message_to_guest" says "send": a word for sending, and what is sent cannot be taken back.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Send 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. Smoobu: POST /api/reservations/{reservationId}/messages/send-message-to-guest.
```

### `smoobu_send_message_to_host`

- The name "smoobu_send_message_to_host" says "send": a word for sending, and what is sent cannot be taken back.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Post 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. Smoobu: POST /api/reservations/{reservationId}/messages/send-message-to-host.
```

### `smoobu_set_rates`

- The name "smoobu_set_rates" says "set": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Set 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). Smoobu: POST /api/rates.
```

### `smoobu_update_reservation`

- The name "smoobu_update_reservation" says "update": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Update 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. Smoobu: PUT /api/reservations/{reservationId}.
```

## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `smoobu_check_availability`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Check 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. Smoobu: POST /booking/checkApartmentAvailability.
```

## Only reads (14)

Looks things up and changes nothing. Claude Code: allow.
