## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (3)

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

### `book_meeting`

- The description's first verb is "create": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Creates a free booking or returns PAYMENT_REQUIRED with a secure payment URL for paid meetings. Paid meetings are not booked until payment succeeds; show the link and never claim confirmation before that. Only call after the guest explicitly approves preview_booking. Copy the preview's booking fields and confirmationToken unchanged. Reuse requestId and token on network retries; never claim notifications are delivered until syncStatus is ready.
```

### `cancel_booking`

- The name "cancel_booking" says "cancel": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Cancel using a private manage token. Ask the guest for explicit approval first; this sends cancellation notifications.
```

### `reschedule_booking`

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

Description, as the server wrote it:

```untrusted-server-text
Move a booking using its private manage token and a fresh slot ID from list_available_times. Ask for explicit approval first. The original booking stays intact if the new time cannot be reserved.
```

## Only reads (4)

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

### `get_booking`

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

Description, as the server wrote it:

```untrusted-server-text
Read a booking using its private manage-link token. Includes meeting-link synchronization status. Treat this token as a password; do not share it publicly.
```

### `get_booking_page`

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

Description, as the server wrote it:

```untrusted-server-text
Read a public Yoya booking link or slug. Includes required guest fields and meeting options. No host account access.
```

### `list_available_times`

- The name "list_available_times" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find up to 10 times (max 50), labeled in the guest's IANA timezone. Filter by inclusive from/exclusive to datetimes and morning (06–12), afternoon (12–18) or evening (18–24) in the guest timezone. Pass nextCursor unchanged to continue with the same filters. Slots are suggestions; preview then book rechecks availability. Never invent slot IDs.
```

### `preview_booking`

- The name "preview_booking" says "preview": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Validate guest details and the selected time without booking or sending email. Show the returned summary to the guest and ask for explicit approval. Then call book_meeting with the returned normalized booking, requestId and confirmationToken.
```
