```


## Deletes or cancels (1)

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

### `check_booking_change_cancel_refund`

- The name "check_booking_change_cancel_refund" says "cancel": a word for removing or ending something.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- The server marks it not destructive (destructiveHint: false), but an annotation never lowers a class.
- Findings: warn annotation-conflict, warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Use this when a traveler asks how to change, cancel or get a refund for their own flight, ferry, hotel or rental booking, check-in, a boarding pass or e-ticket, bags or seats, or a trip the company cancelled or delayed, including one bought via another site or agent. Returns which company handles it and where, dated fees, deadlines and refund rules with sources, and what the traveler does personally. These vary by company and seller and change over time. Useful before opening the site. Read-only.
```

## Can't be undone (1)

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

### `check_flight_compensation`

- 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
Use this when a traveler's flight was cancelled, delayed, overbooked or downgraded and they ask what they are owed or their options: compensation, a refund or care. EU261/UK261 check: verdict with the rule, amount, what the airline owes now, facts that would change it, where the traveler claims (airline, then national enforcement body), evidence. Flights only, not ferries. Dated official sources; stores nothing about the traveler and submits nothing. Not legal advice.
```

## Only reads (1)

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

### `find_official_booking_site`

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

Description, as the server wrote it:

```untrusted-server-text
Use this when a traveler asks how or where to book with a named airline, ferry, hotel, vehicle-rental or booking company. Returns its official site and booking page and, where listed, its own booking channels (app, API, MCP), dated rules with sources and what the traveler does personally. Flags sites not on the company's listed domains. It does not search fares or availability, or book.
```
