About Google Calendar MCP
I also built Cocal, the calendar integration I wanted for chat: a visual calendar inside Claude that shows your whole day around a proposed time, plus booking links and invites you manage from the conversation. It's hosted, so it works on desktop and mobile with no Google Cloud setup.

Cross-Account Conflicts: Detect overlapping events across any combination of calendars
