What you get

Book a three-city call

Rachel Kim, account manager in New York working with London and Warsaw

Ready-to-send text

Tool call	What it did
find_meeting_slots	Ranks slots inside everyone's hours with a fairness score
ics_create	Writes a .ics file with the start stored in UTC

Best slot: 10:00 New York, 15:00 London, 16:00 Warsaw (15:00 UTC). An .ics file path is returned, ready to attach to the email.

Example from "Book a three-city call". Invented names, real math from the tools.

Ask what time it is for a client, when your working hours overlap, or which slot is fair for everyone on a call. It knows daylight saving dates, so a call doesn't quietly move by an hour in March or October. It can write a .ics invite that lands at the right time in any calendar.

Example done on the free tier. Doing this every week? Pro removes the limit for $19, once. Free vs Pro

Example 1 · Rachel Kim, account manager in New York working with London and WarsawBook a three-city call

Find a 45-minute slot next week for me in New York, Oliver in London and Kasia in Warsaw, all 9 to 5 local. Then make the invite for the best one.
- find_meeting_slots Ranks slots inside everyone's hours with a fairness score
- ics_create Writes a .ics file with the start stored in UTC
Best slot: 10:00 New York, 15:00 London, 16:00 Warsaw (15:00 UTC). An .ics file path is returned, ready to attach to the email.

Example 2 · James O'Neill, consultant in Dublin with a weekly client call in ChicagoCheck a weekly call before the clocks change

Our call is 4pm Dublin every Tuesday. When do the clocks change in 2027 for Dublin and Chicago?
- dst_changes Lists the 2027 changes for Chicago: 14 March and 7 November
- dst_changes Lists the 2027 changes for Dublin: 28 March and 31 October
- convert_time Converts 16:00 Dublin to Chicago for a date between the changes
From 14 to 28 March 2027 the gap is 5 hours, not 6, so the call is at 11:00 in Chicago instead of 10:00. James warns the client two weeks ahead.

Saves about 10 min (our estimate)
Example 3 · Zofia Grabowska, freelance developer in Gdansk, Poland with clients in Austin and BerlinKeep client hours at hand

Save Mark in Austin, 8am to 4pm, and Lena in Berlin, 9 to 6. Who can I call right now?
- contacts_set Saves Mark in America/Chicago, 08:00-16:00
- contacts_set Saves Lena in Europe/Berlin, 09:00-18:00
- contacts_list Shows each contact's local time now and whether they are in working hours
At 14:30 in Gdansk, Lena is in hours and Mark isn't (07:30 in Austin). Zofia calls Lena now and messages Mark for later.
