## Findings

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

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

annotations: {"readOnlyHint":true,"idempotentHint":false,"openWorldHint":false}; The description's first verb is "generate": a word for a change.
```


## Changes things (2)

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

### `plan_trips`

- The description's first verb is "generate": a word for a change.
- 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
Generate cheap round trips through several cities, from cached flights. Accepts one departure city (from) or up to 5 (from_cities); with several, a trip can return to a different one of them. Returns trips sorted by total price. To share or book a trip, pass its flight_ids to save_trip.
```

### `save_trip`

- The name "save_trip" says "save": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Save a trip from flight ids returned by search_flights or plan_trips. Returns a public page with the trip and a booking link on Kiwi.com. Prices are confirmed on the booking site.
```

## Only reads (2)

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

### `search_cities`

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

Description, as the server wrote it:

```untrusted-server-text
Find city names we have flights for. Use the exact name in the other tools.
```

### `search_flights`

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

Description, as the server wrote it:

```untrusted-server-text
Cheapest one-way flights between two cities, or from one city to anywhere, from cached airline prices. Dates are a departure window.
```
