Google Calendar MCP Server - Summary

This MCP server enables Claude to interact with Google Calendar, allowing users to list events, create meetings, find free time, and more. It requires Node.js, Claude Desktop, a Google Cloud Project with the Google Calendar API enabled, and OAuth 2.0 credentials.

Setup involves creating a Google Cloud Project, configuring the OAuth consent screen with specific scopes, creating OAuth 2.0 credentials, and obtaining a refresh token using a provided script. The refresh token is then used to configure Claude Desktop by modifying the claude_desktop_config.json file with the necessary environment variables, including client ID, client secret, redirect URI, and refresh token.

The project setup involves initializing an npm project, installing dependencies like @modelcontextprotocol/sdk, googleapis, and zod, creating a tsconfig.json file, and defining a build script in package.json. The server provides tools like list_events, create_event, update_event, delete_event, and find_free_time. Example usages in Claude include scheduling meetings, finding free slots, and updating or canceling events. Troubleshooting tips, log viewing instructions, and security considerations are also provided.
