Tools
list_events- Lists the events of the connected calendar for a range of days.
These tools can only read data. They can't change or send anything.
Sign in
When you connect, a page asks for your calendar's iCal or webcal link.
Your details are encrypted, stored on the server and deleted after 90 days without use. The server's operator can technically access them, so only connect accounts you're comfortable with.
