## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (2)

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

### `ried_taxi_cancel_booking`

- The name "ried_taxi_cancel_booking" says "cancel": a word for removing or ending something.
- The description says "Cannot be undone".
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Cancels a booking, free of charge, any time before the pickup. Requires reference, access code, customer_confirmed=true after the customer explicitly confirmed, and an idempotency_key. Cannot be undone.
```

### `ried_taxi_update_booking`

- The name "ried_taxi_update_booking" says "update": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Changes a booking. Always call first with mode='preview' and show the result to the customer; then call with mode='apply', customer_confirmed=true and an idempotency_key. Same-day time changes, flight number, passengers (max 5), notes and new addresses with the same price apply immediately; a new date or a different price is sent to Ronald for approval (status change_requested).
```

## Changes things (3)

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

### `ried_taxi_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
Checks RIED.TAXI's real calendar (bookings, the owner's own calendar and other customers' temporary holds). One car, one driver: availability depends on the whole day including driving to the pickup and back, not only the minute. Read-only; a free result is NOT a reservation. Returns alternatives when unavailable.
```

### `ried_taxi_create_booking`

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

Description, as the server wrote it:

```untrusted-server-text
Creates a REAL, CONFIRMED booking in RIED.TAXI's booking system and blocks the day. Only call after the customer has seen the complete trip and price and explicitly said yes. Requires the quote_id, customer_confirmed=true, accepted_terms=true and an idempotency_key (retrying with the same key never creates a second booking). Returns the booking reference and an access code for the customer.
```

### `ried_taxi_recheck_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
Re-checks that the quoted date is still free right before the booking. It does NOT block or reserve the day - RIED.TAXI only blocks a day with a created booking. Returns available=true/false (with alternative dates) and held=false. Call it when the customer wants to proceed, then show the summary and create the booking right after their explicit yes.
```

## Only reads (2)

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

### `ried_taxi_get_booking`

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

Description, as the server wrote it:

```untrusted-server-text
Returns status, pickup time, addresses, price and flight of ONE booking. Requires the booking reference and the access code the customer received when booking. Read-only.
```

### `ried_taxi_get_quote`

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

Description, as the server wrote it:

```untrusted-server-text
Returns RIED.TAXI's current price for one journey, calculated by the ried.taxi backend (the only valid price source). Read-only: it never books or reserves anything. Returns quote_id (valid 30 min), status priced | manual_quote_required | not_offered, and the resolved pickup/destination - show those names to the customer. If the result is ambiguous_place, ask the customer which place they mean and resend with the postcode.
```
