Google Calendar

Connects to Google Calendar using service accounts with domain-wide delegation, which means you can manage calendars across a Google Workspace domain without individual OAuth flows. This is built by PulseMCP, who focus on production-ready servers with minimal token usage and tool chain steps. The setup targets workspace administrators who need programmatic calendar access for multiple users. If you're building automation that touches calendars across your organization or need an agent to schedule meetings on behalf of different users, this handles the authentication complexity. Note that it's currently listed as experimental rather than a productionized offering, so check their roadmap if you're deploying to production.
