## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

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

### `cancel_booking_as_invitee`

- The name "cancel_booking_as_invitee" 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
Cancels a booking by its id and token. The event is removed from the host's calendar. Paid bookings cancelled before `refundableUntil` are refunded in full. Later cancellations get no refund. The event type sets the rules, which get_booking shows: no changes after `changeableUntil` (409 change_too_late), no cancelling when `canCancel` is false (409 cancel_not_allowed, reschedule instead).
```

## Changes things (4)

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

### `check_series`

- 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
For event types with `repeatMax` (from get_public_profile): lists each meeting of a series that starts at `start` (one of the slots) and repeats `every` 1, 2 or 4 weeks at the host's clock time, and whether each is free. Pass the invitee's `timezone` to get each meeting's `when` in it: where clocks change on other dates than the host's, some meetings move for the invitee, and `message` says which. Book it with create_booking and `repeat` when `bookable` is true. A series is booked whole or not at all, and round robin gives every meeting to the same host.
```

### `create_booking`

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

Description, as the server wrote it:

```untrusted-server-text
Books `start`, which must be one of the `slots` from get_available_slots. Free events are confirmed at once, unless the event type has `requiresApproval`: then it's a request (status=pending_approval) that holds the time until a host approves or declines it, and the invitee hears either way by email. Nobody answering by its start (`holdExpiresAt`) lets it lapse. Tell the human it isn't confirmed yet. Paid events return status=pending_payment and a `paymentUrl`. Give it to the human to pay before `holdExpiresAt`, or the slot is released. Once confirmed, the event is added to the host's calendar if they connected one, and the invitee gets a confirmation email with a calendar file (.ics). Keep `manageUrl` and `token`: they are the only way to view, reschedule or cancel later. 409 slot_unavailable says why the time can't be booked and lists the `nearest` open times. The result's `when` is the start in the invitee's time zone, to tell them.
```

### `join_waitlist`

- The description's first verb is "request": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Requests access to host on Tempi (create event types, share a booking page). Not needed to book meetings, since booking pages are public. Returns the status: pending, approved (sign in to the Tempi web app), rejected, or open (no waitlist, sign in directly). Joining again with the same email returns the current status.
```

### `reschedule_booking_as_invitee`

- The name "reschedule_booking_as_invitee" says "reschedule": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Moves a confirmed booking to `start` with the same hosts. Get valid times from get_available_slots with this `bookingId` and `token`. The calendar event is updated and its provider notifies attendees. Payment carries over. Not possible after `changeableUntil` (409 change_too_late). A request (status=pending_approval) can’t be moved: cancel it and request another time.
```

## Only reads (3)

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

### `get_available_slots`

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

Description, as the server wrote it:

```untrusted-server-text
Returns the start times that can be booked, with the hosts' calendars, buffers and limits already applied. Pass the invitee's `timezone` and either `date` (YYYY-MM-DD in `timezone`) or `from` and `to` (ISO, at most 62 days apart). With neither, it covers the next 7 days. `days` groups the slots by date in `timezone`, and `times` gives each slot as a local time to show people. People can book up to `bookableUntil`. When the range has no open times, `next` is the next one. When `timezone` was an abbreviation that names more than one zone (CST, IST, BST), `timezoneNote` says which one was used: check it with the person. For new times for an existing booking, also pass its `bookingId` and `token`. Next: call create_booking (or reschedule_booking_as_invitee) with one of the `slots` values as `start`.
```

### `get_booking`

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

Description, as the server wrote it:

```untrusted-server-text
Returns a booking by its id and token (from create_booking), or its manageUrl passed as both, with `changeableUntil`, `refundableUntil` and `canCancel`. For a series, `series` lists every meeting with its own manageUrl.
```

### `get_public_profile`

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

Description, as the server wrote it:

```untrusted-server-text
Takes a handle, the first path segment of a booking link (https://host/acme/demo → "acme"), or the link itself. Returns the person or team and their bookable event types, with duration, price, and hosts with their time zones (`hostTimezones`, so you can say what time a slot is for them). A handle from before a rename also works. Next: call get_available_slots with one of the event type slugs.
```
