Was dieses MCP kann

Imports and reads ICS calendars, lists and searches events, identifies conflicts and free periods, exports events, and converts meetings into time-entry data.

calendars_list
List imported calendars
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.

conflicts
Find double bookings
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.

event_export
Export events to a .ics file
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.

events_list
List events in a window
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_search
Search events
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.

event_to_time_entry
Turn a meeting into a 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.

Without it the time-tracker falls back to USD."}, 'event_id': {'type': 'string', 'maxLength': 200, 'description': 'Event id from events_list, events_search or next_event'}}, 'additionalProperties': False}
free_busy
Busy blocks and free windows
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.

ics_forget
Forget a calendar
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.

{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['name'], 'properties': {'name': {'type': 'string', 'maxLength': 80, 'description': 'The calendar name from calendars_list'}}, 'additionalProperties': False}
ics_import
Import a calendar (.ics)
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.

{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['name'], 'properties': {'url': {'type': 'string', 'maxLength': 4096, 'description': 'Public https:// or webcal:// .ics feed. Fetched once, only because you asked; Pro feature'}, 'name': {'type': 'string', 'maxLength': 80, 'description': 'What to call this calendar, e.g. "work" or "family"'}, 'path': {'type': 'string', 'maxLength': 4096, 'description': 'Not available on this hosted endpoint, which has no filesystem: paste the file as text instead'}, 'text': {'type': 'string', 'maxLength': 5242880, 'description': 'The .ics file contents, pasted'}}, 'additionalProperties': False}
license_activate
Activate license
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.

license_status
License status
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.

next_event
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.
