## Description

The Google Calendar MCP server provides AI assistants with direct access to Google Calendar operations through a Python-based implementation. Built with FastAPI and the Google Calendar API, it enables calendar management (listing, creating), event operations (finding, creating, updating, deleting), and advanced scheduling features like free/busy queries and mutual availability scheduling. The server handles OAuth 2.0 authentication with token refresh, supports both HTTP endpoints and stdio-based MCP communication, and includes detailed logging. It's particularly valuable for users who need to manage their schedules, coordinate meetings, or analyze calendar usage patterns without leaving their AI assistant conversation context.
