## About Google Calendar MCP Server
This community MCP server integrates Google Calendar with AI assistants. It connects several Google accounts at once, lists events across calendars, detects conflicts between them, creates, updates, deletes and searches events including recurring ones, checks free/busy availability, and can add events from images, PDFs or web links.
