Pulled straight from the server with tools/list on 2026-10-18.
license_statusread-only

Report this endpoint's licence state for your token as JSON: the product, the tier free or pro, why it is not Pro, and the checkout URL. Call it to explain a free-tier refusal. No arguments, nothing changes.

license_activate

Turn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.

ics_import

Call this tool to read a calendar export and keep it under a name. Give path (.ics file), text (contents), or url (public .ics/webcal feed; Pro). Google, Apple, Outlook exports read. Re-importing a name replaces it.

calendars_listread-only

List imported calendars: name, event-definition count, size, source, import time and free-tier use of the 2 slots. It also names stored .ics files with no calendar row. With none it prints the export steps.

events_listread-only

Every event between two dates, recurring expanded to occurrences, sorted by start. Times shown in your zone (profile's, else this machine's) unless zone passed. Each id works for event_export or event_to_time_entry.

events_searchread-only

Find events whose title, description, location or attendees contain a phrase. Searches every imported calendar. Without from/to it looks a year back and a year forward on Pro, and the free window either side of today.

free_busy

Merged busy blocks and the free gaps inside your working hours over a day range. Events marked free do not count; whole-day events block the day. Free: 31 days. Use conflicts for overlapping pairs.

conflicts

Find double bookings: every PAIR of timed events that overlap, with the minutes they collide, across all calendars unless you name one. Whole-day events are reported apart. Free: 31 days. free_busy shows gaps.

next_event

The first event not yet started, within the next 366 days, across every imported calendar or one you name. Returns title, times in your zone, how long until it starts, location, attendees and its id.

event_exportread-only

Call this tool to write chosen events to a new .ics file you can send or import elsewhere. Pass either ids (from events_list) or a from/to window. Times are written in UTC so the file lands correctly in any client.

event_to_time_entry

Take one event and return the exact arguments for the time-tracker's entry_add, so a meeting that already happened becomes billable time without retyping it. Writes nothing: pass the JSON straight to entry_add.

ics_forget

Remove one imported calendar by name and delete this server's local copy of its .ics, freeing a slot. Your own calendar and the source file are untouched. ics_import replaces a name in place.
