On a partner-synced boat the hold is placed on that partner too, and with X-Lock on also on the other partner. Returns the stored block and how each hold went. ``` ### `add_calendar` - The name "add_calendar" says "add": a word for a change. Description, as the server wrote it: ```untrusted-server-text Connect an external calendar to a boat: its events block those dates on charter.boats.

Description, as the server wrote it: ```untrusted-server-text Set the company's cancellation policy, company owners only: a guest who cancels at least `cancel_refund_days` before the charter gets `cancel_refund_percent` of the charter price back. The policy applies to the company's MMK and Nausys bookings only; its direct boats follow charter.boats terms, so a company whose boats are all direct is refused. Read get_cancellation_limits first. Returns the company as it now stands. ``` ### `set_cross_lock` - The name "set_cross_lock" says "set": a word for a change. Description, as the server wrote it: ```untrusted-server-text Switch X-Lock for a company, company admins and owners only. With X-Lock on, every block, option or booking placed on one partner calendar (MMK or Nausys) also places a hold on the boat's other partner calendar. `sync_existing` true also places or releases those holds for the bookings and blocks already there. Returns the company as it now stands. Read the current value with its read tool first; this call returns the value as it now stands. ``` ### `set_equipment_visibility` - The name "set_equipment_visibility" says "set": a word for a change.

Description, as the server wrote it: ```untrusted-server-text Change details of one of the operator's boats; only the fields sent change, and a field listed in `locked_fields` is ignored because the partner sync owns it. The answer carries `is_published` and `missing`, what the boat still lacks to be listed. Read the current value with its read tool first; this call returns the value as it now stands. ``` ### `update_boat_images` - The name "update_boat_images" says "update": a word for a change. Description, as the server wrote it: ```untrusted-server-text Hide one photo, show a hidden one again, or set the photo order (the first is the cover); send one of the three.

Claude Code: allow. ### `compare_boat` - The name "compare_boat" says "compare": a word for reading. Description, as the server wrote it: ```untrusted-server-text One boat against the 10 closest published boats of the same type in the same country: specs and the all-in weekly price (in `currency`, EUR when omitted, at max guests, the figure search compares) for each of the next 52 weeks. Pass `id` (a boat), or `boat_type` and `country` (optionally `region`, `city`) to describe one. The specs take search_boats' names: without `id` they describe the boat to compare; with `id` they filter its peers as search_boats would. Only boats open at least one week are compared. `similar_pct` is how alike a peer is: the specs it shares, averaged with `overlap_pct` (the share of the boat's open weeks the peer is open too) when there is a boat. With `id`, `anchor.price` is the boat's weekly figures, a peer's `price` is its figure minus the boat's (its own in the weeks listed in `absolute_weeks`), and a peer carries its `region`, `city`, `same` (the fields it shares with the boat) and only the specs that differ, as signed deltas; without `id` every peer carries its own specs and figures. null = not sellable that week; `weeks` gives each check-in date. Use when someone asks how a boat compares with others nearby on price, size or age — an operator benchmarking their own boat included. For what is better or worse about one boat, use get_boat_standouts. ``` ### `get_availability` - The name "get_availability" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text The company's fleet calendar: every boat with its partner links, and every event that takes dates — bookings, options, blocks and synced partner or iCal events — each with its source. Read it before add_block to see what a range already holds. ``` ### `get_boat` - The name "get_boat" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text One of the operator's boats in full, as its edit page shows it: every editable field, photos with their ids, videos, equipment (hidden items included) and `locked_fields`, the fields MMK or Nausys rewrite on every sync. ``` ### `get_boat_details` - The name "get_boat_details" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Get full details of a specific boat: security deposit, cancellation policy, amenities, fees, seasonal prices, check-in/out times, location details — and the dates it is actually free (priced date ranges plus bookable slots for the year ahead). Use when the user asks about a specific boat, and whenever a boat came back in `named_matches` and they want to know when it IS available. With dates, `stay_price` states Due now, Paid at pickup and Total first, then the charter, its discounts and the deposits. ``` ### `get_boat_standouts` - The name "get_boat_standouts" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text What stands out about ONE boat for one week, measured against similar boats: its pros and its cons, each with how it compares ("47.9 ft (better than 99%)", "€2000 security deposit (typical €1700)", "Rare kit: [0.8%] Cool Box" — n% of those boats have it). Use when the guest asks what is special about a boat, what the catch is, why it is cheap or dear, or how it compares with others. It measures build year, length, cabins, bathrooms, guests, the security deposit and kit — and, with date_from, check-in and check-out times, the changeover day and the open weeks left; any of those it does not list is ordinary among the boats in `compared_with`, so do not sell it as an edge or a catch. Other fees are not compared. Kit is measured two ways and both hold: get_boat_details gives each item its [n%] across the whole fleet, this tool what is rare among boats like it. `rare_kit` lists that rare kit as data, most useful first, each with `useful_score` (1-5: how much it changes a charter week for the people aboard). `note` says whether an absence means "ordinary" or that nothing could be compared. ``` ### `get_booking` - The name "get_booking" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text One booking in full: stage (as in list_bookings), dates, guest, price lines, the operator's payout and `payout_schedule`, the payments coming to the operator with their due dates (empty until the booking is paid). Read-only. ``` ### `get_cancellation_limits` - The name "get_cancellation_limits" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text What the company's payment schedule means for its cancellation policy: per boat source, the share paid in advance and how many days before the charter the rest is due, with the largest refund each notice period covers from money already collected. Read beside get_company's `cancel_refund_percent` and `cancel_refund_days`. `policy_applies` false: the company has no MMK or Nausys boat, so its policy governs nothing and cannot be changed. ``` ### `get_company` - The name "get_company" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text The company profile as its settings page holds it: public profile, contact, bank, tax and invoicing details, the cancellation policy (`cancel_refund_percent` refunded when the guest cancels at least `cancel_refund_days` before the charter), the X-Lock switch (in `settings`) and the member and boat counts. ``` ### `get_earnings` - The name "get_earnings" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text The company's earnings: total and monthly payouts, payouts still pending on accepted bookings, and the latest bookings, in the currency the operator is paid in. ``` ### `get_location_details` - The name "get_location_details" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Get full details of a marina, anchorage or bay by ID: description, amenities, contact, boat count and cheapest day rate, PLUS what only we know from tracked AIS traffic — how busy it is in each month of the year, how boats use it (share of overnight visits, typical day-stop length, what time it fills up), whether it is a hidden gem, the places boats actually sail to from there, most-travelled first with the share of the tracked trips each one takes and an estimated passage time, and the nearest bookable base for a spot with no fleet of its own. Use when the user is viewing or asks about a specific place, asks when it is quiet, or asks where to go next from one. Busyness compares a place to its own peak month, never to another place. ``` ### `get_opportunities` - The name "get_opportunities" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text The company's Opportunities, as the dashboard's Analysis page shows them, read-only. `boats`: every published boat in the dashboard's order (the charted ones first, then by open weeks), with `open_weeks`, `vs_similar_pct` and `compare_url`, its public compare page. `vs_similar_pct` is how far the boat's weekly price sits over (positive) or under (negative) similar boats, as a median over the weeks it can be sold, each week against the median of the other operators' boats among the 10 boats most like it of the same type in the same country, where at least 3 of them are priced (null: no week to compare). `price_suggestions`, up to five: `no_prices` (boats with no priced week in the next 12 months), `under` (a boat 15% or more under similar boats, with its widest week: `week`, `own`, `similar`), `over` (a run of two or more weeks 15% or more over them: `from`, `to` and the `own` and `similar` weekly ranges). `source_checks`, up to five: `feature` (kit sold as an extra but missing from the boats' equipment, so guests filtering for it do not see them), `photos` (boats with under half the photos similar boats have; `similar` is their median), `standout` (what Mermaid and the compare page tell guests a boat trails similar boats on). Figures are weekly totals in EUR, all in at max guests. Empty lists mean nothing to suggest. ``` ### `get_poi_details` - The name "get_poi_details" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Get full details of a point of interest by ID: description, opening hours, address, contact, nearby marinas, special offers. Use when user is viewing or asks about a specific POI. POIs carry NO rating or review count — do not claim one or ask the guest to check it. ``` ### `get_pricing` - The name "get_pricing" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text The season prices of the fleet: per boat, every week-price row with its id, date span (month/day, repeating every year), `price_per_day` and `source`. Rows with `source` mmk or nausys come from the partner and change there; rows with `source` direct are the operator's to edit with add_price, update_price and delete_price. ``` ### `get_trip_details` - The name "get_trip_details" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Get full details of a sailing itinerary/trip by ID: day-by-day stops, distances, activities, highlights, notes. Use when user is viewing or asks about a specific trip. ``` ### `list_boat_fees` - The name "list_boat_fees" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text Every extra and fee row of a boat, as its edit page lists them: amount, period, whether it is required, how it is collected, and its `source`. Rows with `source` direct are the operator's to edit. ``` ### `list_boats` - The name "list_boats" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text The operator's own fleet: every boat of each company the key holder belongs to, published or not, with its company's name, specs, pricing source, changeover settings and photos. Start here: it gives the boat ids and company ids every other operator tool takes. An empty list means the account belongs to no company. ``` ### `list_bookings` - The name "list_bookings" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text Every booking on the operator's boats, newest charter first. `status` and `payment_status` give the stage: `waitlist` is On waitlist (queued behind another hold), unpaid `pending` or `accepted` is an Option that lapses at `hold_expires_at`, and a booking with money in is booked. Each row states the price the guest pays, the discounts and the operator's own payout, in the currency of `payout_money`. Read-only: bookings are handled on the dashboard. An empty list means no bookings yet. ``` ### `list_calendars` - The name "list_calendars" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text The external calendars (iCal feeds, a Google Calendar by its secret iCal address) connected to one boat, with their sync state. MMK and Nausys are linked automatically and are not listed here. An empty list means none is connected to that boat. ``` ### `list_discounts` - The name "list_discounts" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text The company's active discounts: codes guests type at checkout, automatic ones, and the pay-in-full discount, each with its value, booking window (`start_date`..`end_date`), stay window (`stay_from`..`stay_to`) and the boats it covers (`all_boats`, else `boat_ids`). An empty list means the company runs no discount. ``` ### `search_boats` - The name "search_boats" says "search": a word for reading. - Findings: info long-description Description, as the server wrote it: ```untrusted-server-text Search charter boats by location, name, type, dates, capacity, budget. The response `total_matching` is the FULL count of matching boats — results are the top `limit` of those, so phrase counts from it ("8 of 48 available") and re-call with a higher limit when the guest wants more. Pass the guest's dates as they gave them. Each boat sets its own changeover day (`checkinout_days`) and its own minimum stay (`min_charter_days`), so the week a boat can actually be sold may not start on the day asked for — `price_summary` always names the real week, and it is the one sentence to quote, as it stands: the boat page's own Total for the stay it names, for the `guests` given (else the boat's max guests), all in (charter, every required fee charged now or at pickup, the 45 EUR platform fee; refundable deposits never), and the discount applied (the percent the site's card shows); a stay other than a week names its dates and length ("for Jun 19–22 (3 nights), 4 guests"); with no dates it is the boat's lowest week ("From", at max guests, precomputed). `list_price` holds the same figures — `total` (the stay's), `per_day` (that total per day for the boat; `from` when no dates were given), `party` (the guests it is priced for), `original_per_day` and `discount_pct` when a discount applies. For Due now, Paid at pickup and each deposit by name call get_boat_details with the dates. No total here includes an optional extra — `price_summary`, `list_price` and the `total_max` screen all leave out a skipper where `skippered` is 'optional', a hostess, a cook — so for a total with one, call get_boat_details with the dates before you answer and add the fee it lists under `fees.optional`, or say the boat lists none — never a typical or estimated rate, and call no budget met or exceeded on one. When `boats` is short, `alternatives` holds the closest boats, and each one's `relaxed` names what it loosened: `dates` (the week either side), `place` (a nearby base), `model` (another model of the same make), `name` (a boat carrying one word of the name). Say which — they are not what was asked for, and they count toward no total. List them AFTER the matches, in their own list, under a one-line heading naming what was loosened ("Close alternatives — the week either side"): never mixed into the same list. That heading is what splits the two on every card surface, so without it an alternative is rendered exactly like a match. `alternative_inventory` tells you which kind of "no" you are giving: `total_boats` 0 means this coast does not have that boat, while `total_boats` high with `available_nearby_or_within_7_days` 0 means it is the week, not the place. If a plain marina search has neither matches nor alternatives, `listed_unavailable` may carry published boats visibly listed at that exact marina. They are not bookable results: quote no price, explain the supplied reason, and offer an availability alert. A search with NO dates and NO price cap lists every published boat that matches, so `boats` can end with entries we hold no prices for: from `unpriced_start_index` onward every one carries `bookable_as_searched: false` and a `not_offered_because` saying so — they count as matches, but cannot be booked or quoted, so name them, link them and offer an alert without ever stating a price. When you searched a boat by NAME, `named_matches` lists published boats carrying that name that this search could not offer — wrong dates, wrong place, or no prices loaded. Everything bookable AS SEARCHED is in `boats`; nothing in `named_matches` is — though one whose only reason is the place or the dates may still be sellable, which is what its `not_offered_because` tells you. Never say a named boat does not exist while it is in that list: name it, give its reason, and use `get_boat_details` for the dates it IS free. `name_not_found` means the opposite and is certain — that name is in no published boat anywhere. `alert_query` + `alert_horizon` feed availability_alert. Both are abse… [236 more characters not shown] ``` ### `search_content` - The name "search_content" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Search articles and Q&A on charter.boats. Use for questions about booking process, costs, licenses, cancellation, deposits, check-in, packing, etc. For developer questions about our API (endpoints, keys, params), use type=api to search the API docs at docs.charter.boats. ``` ### `search_locations` - The name "search_locations" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Find marinas, harbours and anchorages three ways: by NAME (q), by POPULARITY within an area (region/country/city — ranked on observed AIS vessel traffic for a month), or by REACH from a place you already have (`from` + `within_nm`) — where boats are actually recorded sailing to from there, with measured passage times. Use `from` for "where can I sail from X", "what is a day sail from X", "somewhere quieter nearby". Provide q, or an area, or from. ``` ### `search_pois` - The name "search_pois" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Find restaurants, fuel, groceries, attractions near a location, or search by POI name. POIs carry no ratings — rank and describe them by what they are and how close they are. ``` ### `search_routes` - The name "search_routes" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Find sailing passages between destinations with distance and difficulty. ``` ### `search_trips` - The name "search_trips" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Find existing curated sailing itineraries by location, name, duration, activities. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `charter-boats`: ```json { "permissions": { "allow": [ "mcp__charter-boats__search_boats", "mcp__charter-boats__search_locations", "mcp__charter-boats__search_pois", "mcp__charter-boats__search_routes", "mcp__charter-boats__search_trips", "mcp__charter-boats__search_content", "mcp__charter-boats__get_boat_details", "mcp__charter-boats__get_boat_standouts", "mcp__charter-boats__compare_boat", "mcp__charter-boats__get_poi_details", "mcp__charter-boats__get_location_details", "mcp__charter-boats__get_trip_details", "mcp__charter-boats__list_boats", "mcp__charter-boats__get_boat", "mcp__charter-boats__get_company", "mcp__charter-boats__get_cancellation_limits", "mcp__charter-boats__list_discounts", "mcp__charter-boats__get_pricing", "mcp__charter-boats__list_boat_fees", "mcp__charter-boats__list_calendars", "mcp__charter-boats__get_availability", "mcp__charter-boats__list_bookings", "mcp__charter-boats__get_booking", "mcp__charter-boats__get_earnings", "mcp__charter-boats__get_opportunities" ], "ask": [ "mcp__charter-boats__update_boat", "mcp__charter-boats__set_equipment_visibility", "mcp__charter-boats__update_boat_images", "mcp__charter-boats__update_company", "mcp__charter-boats__set_cancellation_policy", "mcp__charter-boats__set_cross_lock", "mcp__charter-boats__create_discount", "mcp__charter-boats__update_discount", "mcp__charter-boats__add_price", "mcp__charter-boats__update_price", "mcp__charter-boats__add_fee", "mcp__charter-boats__update_fee", "mcp__charter-boats__add_calendar", "mcp__charter-boats__sync_calendar", "mcp__charter-boats__add_block" ], "deny": [ "mcp__charter-boats__delete_boat_image", "mcp__charter-boats__delete_discount", "mcp__charter-boats__delete_price", "mcp__charter-boats__delete_fee", "mcp__charter-boats__remove_calendar", "mcp__charter-boats__remove_block" ] } } ```
