Gongrzhe Calendar Autoauth Mcp Server

Overview

The Calendar AutoAuth MCP Server bridges Claude Desktop and Google Calendar, allowing developers to embed calendar management directly into AI‑driven workflows. By exposing a rich set of event operations—creation, retrieval, update, deletion, and listing—the server turns natural language commands into authenticated API calls. This eliminates the need for developers to write custom OAuth flows or handle token persistence, enabling rapid prototyping of AI assistants that can schedule meetings, check availability, and keep users’ calendars in sync.

What problem does it solve?

Many AI assistants require access to a user’s schedule, but integrating with Google Calendar typically involves complex OAuth setups and manual credential handling. The server abstracts these details, providing a single command line entry point that automatically discovers or copies the OAuth key file, launches the browser for consent, and stores refresh tokens in a global configuration directory. This streamlines onboarding and reduces friction for both developers and end‑users.

Core capabilities

• Event CRUD – Create, read, update, and delete events with full metadata (title, time, description, location).
• Time‑range queries – List all events within a specified window, enabling agenda generation or conflict detection.
• OAuth2 automation – Supports both desktop and web application credentials, auto‑launching the browser for consent and persisting tokens globally.
• Global credential storage – Keeps credentials in , allowing the same account to be used across multiple projects without re‑authentication.
• Docker friendliness – Offers a containerized mode that mounts credential files and persists state, simplifying CI/CD pipelines or isolated environments.

Use cases

• Meeting scheduling assistants that can propose slots, book rooms, and send invites without leaving the chat interface.
• Personal productivity bots that pull calendar events to generate daily summaries or reminders.
• Team coordination tools that aggregate multiple calendars, detect overlaps, and suggest optimal meeting times.
• Automated workflow triggers where calendar events fire downstream actions (e.g., creating tickets, updating project boards).

Integration with AI workflows

The server is registered as an MCP endpoint in Claude Desktop’s configuration, exposing a namespace. AI assistants can call methods like , , or directly from prompts, receiving structured JSON responses that can be further processed. Because the authentication is handled automatically, developers only need to focus on crafting prompts and handling responses—no boilerplate code for OAuth or API pagination is required.

Unique advantages

• Zero‑code authentication: The auto‑auth flow eliminates manual token management, a common pain point in calendar integrations.
• Cross‑platform compatibility: Works seamlessly on both desktop and web OAuth clients, giving developers flexibility in how they host the server.
• Persistent global credentials: A single credential set powers all instances, simplifying multi‑project deployments.
• Docker‑ready: The container image can be pulled and run with minimal configuration, ideal for serverless or cloud‑hosted assistants.

In summary, the Calendar AutoAuth MCP Server empowers developers to give Claude Desktop rich scheduling capabilities with minimal friction, turning conversational AI into a fully functional calendar assistant.
