Connects Claude to the Google Calendar API with full OAuth proxy support, letting you list, create, update, and delete events without storing credentials server-side. Handles the complete calendar workflow: RSVP to invites, find free/busy times, manage recurring events, control calendar sharing via ACLs, and even subscribe to shared calendars. The architecture is clever: it proxies OAuth flows to Google while encoding your callback URL in state, so tokens stay between you and Google. Ships with 15+ tools covering calendars, events, availability queries, and color customization. Reach for this when you want Claude to schedule meetings, block focus time, or answer "what's free Thursday afternoon" without leaving the conversation.
