Script calendar audits with Claude Code

Terminal dwellers can pipe a simple text query into the CLI, and the agent will run `list_bookings` to fetch your entire schedule. It formats the raw JSON into a clean, readable table right in stdout. Want to drill down into a specific meeting? The agent takes the ID from that list and executes `get_booking`. You see the attendee emails, meeting links, and descriptions without ever leaving your SSH session.

Automate team onboarding via MCP Server

You can wrap team onboarding logic into a shell script that authenticates via `get_current_user`. Provisioning new engineers usually involves setting up their default meeting templates. Once verified, it iterates through your standard configurations and fires `create_event_type` for each one. The new hire gets their 15-minute standup and 1-on-1 slots generated instantly.

Handle schedule conflicts headlessly

CI/CD pipelines can check your availability using `get_schedules` against incoming PagerDuty alerts. Imagine a cron job that triggers when a critical incident pops up. Instead of manually declining invites, the script automatically clears your afternoon. It executes `list_bookings` to find non-essential meetings and drops them using `cancel_booking`. Your schedule empties out while you focus on the outage.
