## Tools (10)

- `check_availability`: Check a captain's or boat's availability. Provide exactly one of captainSlug or boatId. Omit date to get available dates for the next 90 days; provide both date (YYYY-MM-DD) and durationHours to get bookable time slots for that date. Each slot lists its offeredDurations, and every entry carries the durationId to pass to get_quote, create_booking, or create_boat_rental (null means that length is offered but not bookable through the API).
- `create_boat_rental`: Book a bareboat boat rental and get a Stripe Checkout link for the charterer to complete payment. Requires captainChoiceRightAcknowledged: true (the charterer affirms their right to choose their own captain). Optionally attach a partner/affiliate code.
- `create_booking`: Book a charter with a captain and get a Stripe Checkout link for the charterer to complete payment. Optionally attach a partner/affiliate code to credit a referrer.
- `get_boat`: Get a boat's full profile by id, enriched with a rating summary and the most recent reviews.
- `get_captain`: Get a captain's full profile by tenant slug, enriched with a rating summary and the most recent reviews.
- `get_quote`: Get a non-binding price quote (in cents) for a charter or rental. Provide exactly one of captainSlug or boatId, plus durationId and partySize. Pass `date` (YYYY-MM-DD) whenever you know it: the rate then comes from the operator's rate card for that day — weekday vs weekend vs holiday, including any per-date price the operator set — so the quote matches what checkout charges. Without a date, pass pricingTierId instead; the quote then reflects that tier and may differ from checkout for the actual day. Optionally pass a partnerCode to preview a discount. Returns currency, totalCents, depositCents, balanceCents, pricingModel, and (when a code is given) a discountPreview.
- `list_harbors`: List active harbors, each with a count of active captains and listed boats operating there.
- `ping`: Health check
- `search_boats`: Search listed boats, optionally filtered by harbor, type, minimum capacity, and max hourly price, with sorting and pagination.
- `search_captains`: Search bookable charter captains, optionally filtered by harbor, with sorting and pagination. Returns a paginated list with starting price and rating.
