Google Calendar MCP Server
A Model Context Protocol (MCP) server that provides Google Calendar integration for AI assistants like Claude.

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.
