## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `message_owner`

- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Send a guest's enquiry to the site owner by email; the owner replies to the guest directly. Suited to sold-out dates, questions the listing details leave open, and request-to-book sites. Requires the guest's name, email address and message.
```

## Changes things (2)

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

### `begin_checkout`

- The name "begin_checkout" says "checkout": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Produce the secure HolidayFox checkout link for a quote. The guest opens the link and pays on holidayfox.com. This tool takes no payment and does not confirm a booking.
```

### `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 dates are free. With destinationId alone it returns the site-wide availability calendar. With accommodationTypeId it returns per-date availability and the party-adjusted nightly price for that one unit. Dates are YYYY-MM-DD and the window is limited to 120 days. Returns availability and nightly prices only; the full stay total comes from get_quote.
```

## Only reads (5)

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

### `get_listing_details`

- The name "get_listing_details" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Full facts about one HolidayFox destination: description, location, amenities, restrictions, check-in/out times, cancellation policy, whether it confirms instantly or by request, and every accommodation type with its size, sleeps, minimum stay and price. Data is live from the HolidayFox booking system.
```

### `get_quote`

- The name "get_quote" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get the authoritative total price for a specific stay directly from the HolidayFox booking system, including any length-of-stay discount and any optional extras passed in `addons`. Returns a quote id for begin_checkout, so the checkout total matches this quote, extras included. Does not hold the dates or make a booking.
```

### `get_reviews`

- The name "get_reviews" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read published guest reviews for a HolidayFox destination — star ratings, what guests said, and any reply from the owner. Returns an average rating and the most recent reviews.
```

### `list_addons`

- The name "list_addons" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the optional extras a specific accommodation type offers — things like firewood, a hot-tub session, an extra guest, or breakfast — with their prices. Returns product ids accepted by get_quote as `addons`.
```

### `search_stays`

- The name "search_stays" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search HolidayFox for UK holiday accommodation — farm stays, glamping, shepherd huts, caravan and camping pitches, and self-catering cottages. Filter by area and by amenity/audience tags. When checkinDate and checkoutDate are supplied, each result carries the live total price for that exact stay and only genuinely bookable options are counted. Returns destination ids used by the other tools.
```
