Temporal Cortex MCP tools 18

• adjust_timestampAdjust a timestamp by adding or subtracting a duration. DST-aware: '+1d' preserves wall-clock time across daylight saving transitions.
• book_slotBook a calendar slot using Two-Phase Commit for safe, conflict-free booking.
• check_availabilityCheck if a calendar time slot is available (not held by another booking).
• compose_proposalCompose a scheduling proposal message with proposed time slots. Formats times in the specified timezone for email, Slack, or SMS. Does NOT send the message — returns formatted text for the agent to send via its channel MCP (Gmail, Slack, etc.).
• compute_durationCompute the duration between two timestamps. Returns days, hours, minutes, seconds, and a human-readable string.
• convert_timezoneConvert a datetime to a different timezone.
• expand_rruleExpand a recurrence rule (RRULE) into concrete event instances.
