Google Calendar MCP Server

Google Calendar MCP Server

The Google Calendar MCP server bridges the gap between conversational AI assistants and the rich scheduling capabilities of Google Calendar. By exposing a standardized set of resources, tools, and prompts, it allows AI agents such as Claude to query, create, update, and delete events across multiple calendars without requiring the user to leave the chat interface. This integration turns an AI assistant into a full‑featured calendar manager, enabling natural language interactions that feel intuitive and productive.

At its core, the server offers multi‑calendar support so users can view events from several calendars in a single query. It provides comprehensive event management—creating new appointments, editing existing ones, or removing them entirely. The system understands recurring event patterns and can modify series-wide rules, making it possible to adjust a weekly meeting or cancel a whole event chain with a single command. A free/busy query feature lets the assistant check availability across all calendars, which is essential for scheduling meetings that involve multiple participants. The server also incorporates smart scheduling: natural language parsing of dates, times, and durations enables the assistant to interpret vague inputs like “next Thursday at 3” or “in two weeks.” Finally, an intelligent import capability allows users to add events from images, PDFs, or web links, expanding the assistant’s reach beyond manual entry.

Developers can leverage these capabilities to build a wide range of use cases. For example, a productivity bot could automatically add meeting notes from a conversation to the appropriate calendar slot, or an event‑planning assistant might suggest optimal times for a group based on free/busy data. In customer support scenarios, agents can book callbacks or follow‑up appointments directly from the chat window. The server’s design also supports advanced workflows, such as triggering reminders or notifications when an event is about to start, all orchestrated through MCP commands.

What sets this MCP server apart is its seamless OAuth integration and the ability to operate in multiple deployment modes (npx, local, Docker), giving teams flexibility while maintaining a consistent API surface. The inclusion of intelligent import and smart scheduling means developers do not need to build these features from scratch; they can rely on the server’s built‑in natural language understanding. Overall, the Google Calendar MCP server empowers AI assistants to become reliable, context‑aware calendar companions that streamline scheduling and reduce friction in everyday workflows.
