## Findings

No check matched anything in these tool definitions.


## Changes things (4)

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

### `create_flight_alert`

- The name "create_flight_alert" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Sets up an email alert for new empty legs on a route or from a place, for when the user asks to be notified and gives their email. voidjet emails a confirmation link; the alert becomes active only after the user clicks it (double opt-in, valid 7 days). Needs origin or destination; dates, passengers and budget are optional.
```

### `report_unmet_need`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Records a need voidjet cannot serve, for when the user wants voidjet to know about it: e.g. no offer on the route, a return flight, pets, instant booking. Takes 1-5 categories and optional route, dates, passengers and budget; no personal data. Helps voidjet decide what to add.
```

### `request_charter_quote`

- The name "request_charter_quote" says "request": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Requests confirmed charter prices from partner Villiers for the route of a charter_alternative, for when the user has seen its price range, asked for confirmed prices and given their email. NOT an empty leg: a regular charter and a paid partner offer. voidjet emails the user a link; Villiers receives the request only after the user sends the form on voidjet.io within 48 hours, then emails confirmed options directly. name, phone and message are optional and come from the user.
```

### `request_inquiry`

- The name "request_inquiry" says "request": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Prepares an inquiry for one offer, for when the user has asked to inquire and given their email. voidjet emails the user a link; nothing is forwarded to the provider until the user opens it and sends the pre-filled form on voidjet.io within 48 hours. name, phone and message are optional, come from the user and only pre-fill the form. Prices are indicative.
```

## Only reads (2)

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

### `get_empty_leg`

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

Description, as the server wrote it:

```untrusted-server-text
Current details of one offer by the ref returned by search_empty_legs. available=false means the offer is no longer listed.
```

### `search_empty_legs`

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

Description, as the server wrote it:

```untrusted-server-text
Finds current empty-leg flights by origin and/or destination (city, IATA/ICAO code, country, US state, region or area such as Greek Islands), dates, passengers, budget and aircraft class. Returns up to 20 offers with route, date, aircraft, seats, indicative price, a voidjet link and a pre-filled inquiry link; provider names are not included. When more offers match, refine summarises all matches (frequent destinations, date span, prices). With no match, charter_alternative may contain a regular charter via partner Villiers: NOT an empty leg, and a paid partner offer.
```
