## Findings

- **warn** Annotations that disagree with the tool in `check_availability` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "check_availability" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":false}; The input addresses people (input.to): what it sends cannot be taken back.
```


## Can't be undone (1)

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

### `check_availability`

- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Booked nights and the open date ranges a stay can actually be booked in, with minimum-stay rules applied. bookableUntil is the first night the host's booking window has not opened yet (null for no limit); nights after it are not open rather than taken. Defaults to the next 90 days; at most 365 days per call. Ranges are check-in inclusive, check-out exclusive.
```

## Only reads (3)

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

### `find_property`

- The name "find_property" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up a vacation rental by its RentalCal booking site, or by the page on the host's own website where their RentalCal booking widget is installed. Accepts a site address such as beach-house.rentalcal.com, a full URL, the bare site name, or the host's own domain. Returns the listing: description, location, capacity, amenities, house rules, photos, nightly pricing, cancellation policy, payment schedule, damage deposit, the host's FAQ, and the property id. When one website hosts several properties, returns those candidates instead.
```

### `get_property`

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

Description, as the server wrote it:

```untrusted-server-text
The full listing for a property id: description, location, check-in and check-out times, capacity, pets, amenities, house rules, photos, nightly pricing and fees, cancellation policy, payment schedule, damage deposit, and the host's FAQ. Amounts are integer cents in the property's currency.
```

### `get_quote`

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

Description, as the server wrote it:

```untrusted-server-text
The exact price of a stay: nightly rates, discounts, cleaning and other fees, taxes and total, in integer cents, plus any refundable damage deposit the host requires and whether it is held at booking. Returns a bookingUrl that opens the host's booking page with these dates and guests filled in, where the traveller completes the booking. If the stay is not allowed (dates taken, below the minimum stay, too many guests) the reason is returned instead.
```
