The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
book_group_meeting ~295

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.

NameTypeReqDescription
durationMinutesintegeryesMeeting length in minutes. Must be one the organizer offers.
participantHandlesarrayyesThe other participants' @handles, e.g. ["@lucie", "@taylor"]. Each must have a live Lucie booking page. Leading @ optional.
reasonstringyesA short agenda/purpose, shared with everyone on the invite.
startAtstringyesThe exact ISO-8601 `start` copied verbatim from a find_group_times common slot (absolute UTC instant). Do NOT construct it from a wall-clock time.
titlestringyesThe meeting title, e.g. "Q3 planning sync".

book_meeting ~409

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).

NameTypeReqDescription
bookerEmailstringyesThe booker's email. The confirmation and calendar invite are sent here.
bookerNamestringyesFull name of the person the meeting is for (the booker).
durationMinutesintegeryesMeeting length in minutes. Must be one the host offers.
handlestringyesThe host's booking handle, e.g. "@alice" or "alice" (the leading @ is optional).
reasonstringyesA short description of why the booker wants to meet (the agenda / purpose). Required — ask the booker for it before booking. Shared with the host alongside the invite.
startAtstringyesThe exact ISO-8601 `start` value copied verbatim from a check_availability slot (an absolute UTC instant, e.g. 2026-07-28T17:00:00Z). Do NOT construct this from a local wall-clock time the booker sai…

No output schema declared.

No examples provided.

check_availability ~287

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.

NameTypeReqDescription
durationMinutesinteger–Desired meeting length in minutes. Must be one the host offers. Defaults to 30 if omitted.
fromstring–ISO-8601 start of the search window. Defaults to now + the host's minimum notice.
handlestringyesThe host's booking handle, e.g. "@alice" or "alice" (from their lucie.network/book/@<handle> link). The leading @ is optional.
tostring–ISO-8601 end of the search window. Defaults to the host's max-advance horizon.
viewerTimeZonestring–The booker's IANA time zone, e.g. "Asia/Singapore" or "America/New_York". Pass the booker's own zone so slots are shown in their local time. Defaults to the host's zone if omitted.

No output schema declared.

No examples provided.

create_group_event ~275

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).

NameTypeReqDescription
durationMinutesinteger–Meeting length in minutes. Defaults to 30.
fromstring–ISO-8601 start of the search window.
handlesarrayyesParticipants' @handles whose availability seeds the candidate times. The leading @ is optional.
organizerEmailstringyesThe organizer's email.
organizerNamestringyesThe organizer's name (shown on the poll).
timeZonestring–IANA time zone for the poll's displayed times, e.g. "America/New_York". Defaults to UTC.
titlestringyesThe meeting title, e.g. "Q3 planning sync".
tostring–ISO-8601 end of the search window.

No output schema declared.

No examples provided.

find_group_times ~212

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.

NameTypeReqDescription
durationMinutesinteger–Meeting length in minutes. Must be one every participant offers. Defaults to 30.
fromstring–ISO-8601 start of the search window.
handlesarrayyesThe participants' booking handles, e.g. ["@alice", "@bob"]. The leading @ is optional.
tostring–ISO-8601 end of the search window.
viewerTimeZonestring–The organizer's IANA time zone, e.g. "America/New_York". Common times are shown in this zone. Defaults to UTC.

Install

How do I install the network.lucie/sync MCP server?

network.lucie/sync is a hosted endpoint at https://sync.lucie.network/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.
