FAQ from Calendar MCP Server

What does Calendar MCP Server require to run?

You need a Google Cloud Project with the Calendar API enabled, OAuth 2.0 credentials (client ID and secret), and a refresh token obtained from the OAuth 2.0 Playground. The server runs via npx or a local npm installation.

How does authentication work?

The server uses OAuth2 with your own credentials. You must provide GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET, and GOOGLE_REFRESH_TOKEN as environment variables. The refresh token grants access to your Google Calendar.

Where are calendar events stored?

Events are stored in your Google Calendar account. The server acts as a bridge; no data is stored locally beyond temporary API calls.

How do I keep my credentials secure?

Keep your Google API credentials secret, rotate refresh tokens regularly, store sensitive info in Claude Desktop configuration, and never share or commit credentials to version control.

What transport and communication does this server use?

The server communicates via the MCP protocol over standard input/output when launched as a command-line process by Claude Desktop.
