## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 60/100
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 884 tokens (~88/item across 10 items; 10 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 67/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

### `get_boat` (~37 tokens)

Get Boat

Get a boat's full profile by id, enriched with a rating summary and the most recent reviews.

Input parameters:

- `boatId` (string, required)

### `list_harbors` (~29 tokens)

List Harbors

List active harbors, each with a count of active captains and listed boats operating there.

### `check_availability` (~94 tokens)

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.

Input parameters:

- `boatId` (string)
- `captainSlug` (string)
- `date` (string)
- `durationHours` (integer)

### `get_quote` (~215 tokens)

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.

Input parameters:

- `boatId` (string)
- `captainSlug` (string)
- `date` (string)
- `durationId` (string, required)
- `partnerCode` (string)
- `partySize` (integer, required)
