## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-29.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (cancel_booking_as_invitee).
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 64/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1516 tokens (~189/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.

## MCP tools (8)

### `get_public_profile` (~103 tokens)

List a person's or team's event types

Takes a handle, the first path segment of a booking link (https://host/acme/demo → "acme"). Returns the person or team and their bookable event types, with duration, price and hosts. A handle from before a rename also works. Next: call get_available_slots with one of the event type slugs.

Input parameters:

- `handle` (string, required): 1-40 lowercase letters, digits or dashes, starting and ending with a letter or digit

### `get_available_slots` (~261 tokens)

Find open times

Returns the start times that can be booked, with the hosts' calendars, buffers and limits already applied. Pass `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` (default UTC). 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`.

Input parameters:

- `bookingId` (string): a string at least 1 character(s) long
- `date` (string)
- `from` (string)
- `handle` (string, required): 1-40 lowercase letters, digits or dashes, starting and ending with a letter or digit
- `slug` (string, required): 1-40 lowercase letters, digits or dashes, starting and ending with a letter or digit
- `timezone` (string): an IANA time zone such as "America/New_York"
- `to` (string)
- `token` (string): a string at least 10 character(s) long

### `check_series` (~175 tokens)

Check a repeating series before booking it

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 same local time, and whether each is free. 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.

Input parameters:

- `count` (required)
- `every` (required)
- `handle` (string, required): 1-40 lowercase letters, digits or dashes, starting and ending with a letter or digit
- `slug` (string, required): 1-40 lowercase letters, digits or dashes, starting and ending with a letter or digit
- `start` (string, required)

### `create_booking` (~346 tokens)

Book a meeting

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. 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 its invitation. Keep `manageUrl` and `token`: they are the only way to view, reschedule or cancel later. 409 slot_unavailable means the time was just taken: fetch slots again.

Input parameters:

- `email` (string, required)
- `handle` (string, required): 1-40 lowercase letters, digits or dashes, starting and ending with a letter or digit
- `name` (required): the invitee's full name
- `notes` (string): a string at most 2000 character(s) long
- `repeat` (object): book a series instead: `count` meetings, `every` 1, 2 or 4 weeks at the same local time, when the event type's repeatMax allows. All or nothing: check_series first
- `slug` (string, required): 1-40 lowercase letters, digits or dashes, starting and ending with a letter or digit
- `start` (string, required)
- `timezone` (string): an IANA time zone such as "America/New_York"

### `get_booking` (~96 tokens)

View a booking (invitee)

Returns a booking by its id and token (from create_booking or its manageUrl), with `changeableUntil`, `refundableUntil`, `canCancel` and `cancelReasonRequired`. For a series, `series` lists every meeting with its own manageUrl.

Input parameters:

- `id` (string, required): a string at least 1 character(s) long
- `token` (string, required): a string at least 10 character(s) long

### `reschedule_booking_as_invitee` (~115 tokens)

Reschedule a booking (invitee)

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).

Input parameters:

- `id` (string, required): a string at least 1 character(s) long
- `start` (string, required)
- `token` (string, required): a string at least 10 character(s) long

### `cancel_booking_as_invitee` (~183 tokens)

Cancel a booking (invitee)

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), and a `reason` when `cancelReasonRequired` is true (422 reason_required).

Input parameters:

- `following` (boolean): for a series: also cancel every later meeting
- `id` (string, required): a string at least 1 character(s) long
- `reason` (string): a string at most 500 character(s) long
- `token` (string, required): a string at least 10 character(s) long

### `join_waitlist` (~148 tokens)

Join the private beta waitlist

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 at APP_URL/login), rejected, or open (no waitlist, sign in directly). Joining again with the same email returns the current status.

Input parameters:

- `email` (string, required)
- `name` (string): a string at most 100 character(s) long
- `note` (string): anything the admins should know, e.g. what you want to use Tempi for
- `ref` (string): a short source tag of lowercase letters, digits, - or _, like "embed"

### Is the Tempi MCP server safe to use?

Tempi scores 64 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Tempi MCP server expose?

Tempi exposes 8 tools: get_public_profile, get_available_slots, check_series, create_booking, get_booking, and 3 more. Their descriptions and schemas cost roughly 1,427 tokens of context every time the server is loaded.

### Does the Tempi MCP server require authentication?

No. We connected to Tempi without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
