## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (2)

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

### `hotelrunner_update_reservation_state`

- The name "hotelrunner_update_reservation_state" says "update": a word for a change.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
WRITE: move ONE reservation to the next state: event 'confirm' (hotelier accepts it) or 'cancel' (cancels it; cancel_reason is required: customer, no_room, no_show or invalid_price). Cancel is not reversible through this API and releases the room; HotelRunner may notify the guest or the sales channel (Booking.com, Expedia, ...), so only cancel when the user clearly asked for it, and pass confirm=true for a cancel. Only possible when the reservation's requires_response is true and the event is in its next_states (see hotelrunner_get_reservation); otherwise HotelRunner answers state_change_is_not_available. Counts as one of the property's 250 requests per day (5 per minute). PUT /api/v2/apps/reservations/fire.
```

### `hotelrunner_update_room_calendar`

- The name "hotelrunner_update_room_calendar" says "update": a word for a change.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
WRITE: change availability, price, minimum/maximum stay, stop-sale, closed-to-arrival (cta) or closed-to-departure (ctd) for ONE room type (inv_code) over a date range of at most 90 days, optionally only on some weekdays and only on some channels. Only the fields you pass are changed. This is LIVE inventory: HotelRunner pushes it to every connected channel (Booking.com, Expedia, your own booking engine, ...) and it changes what guests can book and pay. The price is the base-rate price in the property's sales currency; guest-based prices derive from it. Only rooms whose availability_update / restrictions_update / price_update flag is true (hotelrunner_list_rooms) accept that kind of change. HotelRunner answers asynchronously: the reply has a transaction_id; check per-channel results with hotelrunner_get_transaction_details. Send one change per call, not a full refresh. Counts as one of the property's 250 requests per day (5 per minute). PUT /api/v2/apps/rooms/daily.
```

## Only reads (6)

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

### `hotelrunner_get_reservation`

- The name "hotelrunner_get_reservation" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
One reservation by its HotelRunner code (hr_number, e.g. R377873409) or the sales channel's own reservation code, with the full vendor record (rooms, daily prices, extras, payments, guest and billing details, next_states). If the reservation is older than HotelRunner's lookup window, pass from_date. Counts as one of the property's 250 requests per day (5 per minute). GET /api/v2/apps/reservations?reservation_number=.
```

### `hotelrunner_get_transaction_details`

- The name "hotelrunner_get_transaction_details" says "get": a word for reading.
- Tag private-data: The description's first sentence says "calendar": it reads calendars.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Per-channel status of a calendar update: pass the transaction_id returned by hotelrunner_update_room_calendar. Shows succeeded / failed / in-progress counts and each channel's state and error message. Counts as one of the property's 250 requests per day (5 per minute). GET /api/v2/apps/infos/transaction_details.
```

### `hotelrunner_list_channels`

- The name "hotelrunner_list_channels" says "list": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
All sales channels HotelRunner supports (name and code, e.g. bookingcom, expedia, hrs, online). The code is what hotelrunner_update_room_calendar takes in channel_codes. Counts as one of the property's 250 requests per day (5 per minute). GET /api/v2/apps/infos/channels.

The channels this property is connected to, each with counts of calendar update processes in progress, succeeded and failed. Counts as one of the property's 250 requests per day (5 per minute). GET /api/v2/apps/infos/connected_channels.
```

### `hotelrunner_list_reservations`

- The name "hotelrunner_list_reservations" says "list": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
List reservations of the property (new, modified, canceled), newest data first as HotelRunner returns them, 1-50 per page. By default ALL reservations created in the window are returned (this tool sets undelivered=false, so reading does not depend on a PMS having fetched them). from_date is the creation date (HotelRunner keeps at most 30 days back; default 10 days); from_last_update_date finds reservations changed since a date. detail 'summary' (default) gives guest, dates, rooms, totals, payment state and contact; 'full' returns the whole vendor record including billing address, national id, daily prices and extras. Reply: items, count, page, pages, next_page. Counts as one of the property's 250 requests per day (5 per minute). GET /api/v2/apps/reservations.
```

### `hotelrunner_list_rooms`

- The name "hotelrunner_list_rooms" says "list": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

Use the inv_code with hotelrunner_update_room_calendar. Counts as one of the property's 250 requests per day (5 per minute). GET /api/v2/apps/rooms.
```
