# What your assistant can do

A connected assistant works with 42min through a fixed set of **24 tools**.
You don't call these yourself — the assistant picks the right one from your
request ("find me a slot tomorrow" becomes a `find_available_slots` call). This
page lists them all in plain language, so you know exactly what an assistant
can and cannot do with your account.

Which tools an assistant actually gets depends on the access it was granted —
an assistant connected with a read-only
[personal access token](/help/ai-assistants/connecting-your-assistant#two-ways-to-sign-in)
sees only the reading tools. And every tool respects your dashboard role — see
[Permissions and security](/help/ai-assistants/permissions-and-security).

## Availability and slots

| Tool | What it does |
|---|---|
| `find_available_slots` | Lists open booking slots for an event type over a date range (up to 31 days at a time). |
| `check_slot` | Checks whether one specific start time is bookable. |
| `get_schedules` | Reads your own availability schedules — weekly hours and date overrides. |
| `add_schedule_override` | Adds or replaces a [date-specific override](/help/schedules-availability/weekly-hours-and-overrides) on one of your schedules. |

## Bookings and meetings

| Tool | What it does |
|---|---|
| `list_bookings` | Lists bookings, filtered by status, date range, event type, attendee, or host. |
| `get_booking` | Full detail for one booking — form responses, location or conferencing link, no-show status. |
| `create_booking` | Books a meeting for an attendee on any active event type in your organization — the same thing the public booking page allows. |
| `cancel_booking` | Cancels a booking. The attendee is notified and the calendar event is removed. |
| `reschedule_booking` | Moves a booking to a new time. |
| `list_meetings` | Your host-side meetings view — upcoming, past, or a date range. |
| `set_meeting_no_show` | Marks (or unmarks) a past meeting as a no-show. |

## Event types

| Tool | What it does |
|---|---|
| `list_event_types` | Lists event types, optionally filtered by status, host, or slug. |
| `get_event_type` | Full detail for one event type — duration, location, booking questions, limits. |
| `set_event_type_status` | Turns an event type on or off. Turning it off immediately stops new public bookings. |

## Contacts

| Tool | What it does |
|---|---|
| `search_contacts` | Searches contacts by name or email, with meeting counts and tags. |
| `get_contact` | One contact plus their meeting history. |

## Single-use links

| Tool | What it does |
|---|---|
| `create_single_use_links` | Generates one-time [booking links](/help/booking-pages/single-use-links) (1–10 at a time) for an event type you manage. |
| `list_single_use_links` | Lists your one-time links with created / booked / expired status. |
| `delete_single_use_link` | Deletes an unused one-time link so it can no longer be used. |

## Roundtables (group scheduling polls)

| Tool | What it does |
|---|---|
| `list_roundtables` | Lists your [roundtables](/help/roundtables/overview) with status, vote counts, and the confirmed time. |
| `get_roundtable` | Full poll state — candidate slots, participants, vote tallies. |
| `create_roundtable` | Creates a **draft** poll with candidate time slots and participants. Drafts send no emails and place no calendar holds. |
| `publish_roundtable` | Publishes a draft — opens voting, emails every invited participant, and places tentative calendar holds. Assistants are instructed to confirm with you before calling this, because it can't be undone through MCP. |

## Your profile

| Tool | What it does |
|---|---|
| `get_me` | Your own profile — name, username, time zone, language — plus your organization and role. |

## What it can't do

There are deliberately no tools for some things, no matter what access was
granted:

- **Create or delete event types.** The assistant can list, inspect, and
  toggle them, but building an event type stays in the
  [dashboard](/360/events).
- **Change org settings, users, teams, or branding** — no admin-center tools.
- **Manage webhooks, routing forms, or workflows.**
- **Act for your invitees.** Attendees book, reschedule, and cancel through
  your [booking page](/help/booking-pages/the-booking-flow) and their emailed
  links, not through an assistant.

## Common pitfalls

- **Booked a colleague's event type, now the assistant can't cancel it.** A
  booking created on someone else's event type behaves like one made through
  their public page: the attendee manages it via the emailed reschedule and
  cancel links, and only people with
  [access to that host's bookings](/help/ai-assistants/permissions-and-security)
  can touch it in 42min.
- **"Publish" is permanent.** Publishing a roundtable emails all participants
  immediately — that can't be recalled. Keep polls as drafts until they're
  ready.
- **Safety on retries.** Booking-creating tools are idempotent: if the
  assistant retries after a timeout, 42min recognizes the repeat and won't
  double-book. In rare cases a duplicate *notification email* can go out even
  though the booking itself was created exactly once.
