## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `create_group_event`

- The name "create_group_event" says "create": a word for a change.
- The input addresses people (input.to): what it sends cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Create a Lucie group event (a poll) for several participants, pre-filled with candidate times when everyone is free (the intersection of their availability). Returns a vote link to share: participants pick which proposed times work, and people WITHOUT a Lucie handle can vote manually too. This is a write (creates a poll) but sends no emails and touches no calendars. Confirm the title, participants, and duration with the organizer before creating. Note: agent group scheduling is a Sync Pro feature — the organizer's email must be on Sync Pro (or a Lucie Membership).
```

## Changes things (2)

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

### `book_group_meeting`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Confirm a group meeting at a specific time across several Lucie hosts (by @handle), creating ONE shared Google Calendar event with everyone invited. YOU (the connector's owner) are the organizer and host the event on your calendar — no organizer handle needed. This is a real write: it re-verifies every participant (you included) is free at that instant and refuses if anyone isn't — so it never double-books. Always call find_group_times first and copy an exact common-slot start. Before calling, confirm the time (in each person's zone), the participants, the title, and the reason. Requires you to be on Sync Pro (or a Lucie Membership) via your personal connector; everyone must have a live booking page.
```

### `book_meeting`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Book a confirmed meeting on a Lucie Sync host's calendar at a specific start time. This is a real write: it creates a calendar event and emails both the host and the booker. Always call check_availability first and use one of the open slots it returns. Before calling, (1) show the booker the specific date/time you're about to book — in their own time zone — and get their explicit confirmation, and (2) collect their name, email, AND a brief reason for the meeting (ask for the reason if not given; it's required and shared with the host).
```

## Only reads (2)

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

### `check_availability`

- The description's first verb is "return": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return the open meeting slots a Lucie Sync host offers, plus their booking rules (durations offered, minimum notice, how far ahead you can book, buffer between meetings). Returns only bookable slots and policy — never the host's raw calendar. Use this to find a time before proposing one to the user. Slots are absolute instants (ISO-8601 UTC). Pass the booker's viewerTimeZone so times display in THEIR local zone — the booker should never have to do time-zone math.
```

### `find_group_times`

- The name "find_group_times" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Given several Lucie hosts (by @handle), return the meeting times when ALL of them are free — the intersection of their availability — for a meeting of the given length. Read-only: never books, never exposes anyone's raw calendar (only the shared open slots). Use it to propose a group time. Times are absolute instants; pass viewerTimeZone so they show in the organizer's local zone.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `sync`:

```json
{
  "permissions": {
    "allow": [
      "mcp__sync__check_availability",
      "mcp__sync__find_group_times"
    ],
    "ask": [
      "mcp__sync__book_meeting",
      "mcp__sync__create_group_event",
      "mcp__sync__book_group_meeting"
    ],
    "deny": []
  }
}
