Resolve a place 'query' to coordinates (forward) or find nearest places to 'latitude'+'longitude' (reverse). Mediterranean-focused curated DB; forward falls back to OSM/Nominatim globally. Each result carries a 'source' discriminator ('local' for the curated marine DB, 'osm' for the global fallback). Returns name, type, coords, source, plus similarity (forward) or distance_m (reverse). Example forward: query="Portofino". Example reverse: latitude=44.3, longitude=9.21, radius_m=50000. When the same name exists in several seas (e.g. "Salerno port": Italy and Florida), results carry a 'region' and the best of each sea is included — pick by the user's context, or pass near_latitude/near_longitude (boat position, departure port) to put that sea first. Chain into nausika_marine_forecast, nausika_tides, nausika_search_places, or nausika_sea_route using the returned coords.

Mediterranean nautical place search by proximity. latitude+longitude are ALWAYS required — this is not a standalone text search. 'query' is only a name filter applied within that radius; to find a place by name without known coordinates, call nausika_geocode first. Returns name, coords, distance_km, ratings, i18n names, wiki/OSM links. Each result is prefixed with an 8-char [xxxxxxxx] short-id usable as place_id in nausika_get_place / nausika_manage_favorite / nausika_manage_rating / nausika_manage_route legs[].pois[]. Inputs: latitude, longitude, radius_km, query, type, types, category, shelter_from, bottom_type, names_lang, min_coverage_score, max_coverage_score, limit, offset. Example: latitude=44.3, longitude=9.21, radius_km=50, query="marina genova", category="poi". Chain nausika_geocode → nausika_search_places → nausika_get_place(short-id).

Tools (19)

`nausika_calculator`read-only	Evaluate a math expression and return the numeric result. Useful for fuel, range/autonomy, unit conversions, and ad-hoc arithmetic. Supported (exhaustive): +, -, , /, ^, %, parentheses, sqrt(), abs(), ceil(), floor(), round(), sin(), cos(), tan(), log(), exp(), min(), max(), PI, E. Anything else (atan2, pow, log10, hypot, if, factorial, comparisons) is rejected. Examples: "(120 / 6) 8.5" (fuel for 120 nm at 8.5 L/h, 6 kn); "45 * 1.852" (nm to km).
`nausika_convert_coordinates`read-only	Convert nautical coordinates between decimal degrees, DMS, and DM. Inputs: latitude, longitude — each accepts decimal (44.4), DMS ("44°24'00\"N"), or DM ("44°24.0'N"). Returns all three formats plus input_format (detected per-axis). Examples: latitude="44°24'N", longitude="9°02'E" → 44.4, 9.03; latitude="41°01'44.04\"N", longitude="009°32'42.00\"E" → 41.0289, 9.545.
`nausika_describe_place_schema`read-only	Returns the expected attributes for a given place 'type' (the only input parameter: marina, port, bay, fuel_station, city, island, etc.). Useful to understand what fields are available on places of that type.
`nausika_geocode`read-only	Resolve a place 'query' to coordinates (forward) or find nearest places to 'latitude'+'longitude' (reverse). Curated DB of the covered sea areas (Mediterranean, European Atlantic + Canaries, Caribbean, South-East Asia); forward falls back to OSM/Nominatim globally. Each result carries a 'source' discriminator ('local' for the curated marine DB, 'osm' for the global fallback). Returns name, type, coords, source, plus similarity (forward) or distance_m (reverse). Example forward: query="Portofino". Example reverse: latitude=44.3, longitude=9.21, radius_m=50000. When the same name exists in several seas (e.g. "Salerno port": Italy and Florida), results carry a 'region' and the best of each sea is included — pick by the user's context, or pass near_latitude/near_longitude (boat position, departure port) to put that sea first. Chain into nausika_marine_forecast, nausika_tides, nausika_search_places, or nausika_sea_route using the returned coords.
`nausika_get_boat_profile`read-only	Get your saved boat profile(s). Omit name for the default boat, or use name="*" to list all boats. Tip: use boat speed/consumption with nausika_sea_route and nausika_calculator for trip planning.
`nausika_get_favorites`read-only	List your favorite places with details and personal notes. Ordered by most recently added. Inputs: limit, offset. Tip: use place coordinates with nausika_sea_route or nausika_marine_forecast for trip planning.
`nausika_get_place`read-only	Fetch full detail for a single place given its 'id'. Accepts either a full UUID or the 8-char [xxxxxxxx] short-id shown by nausika_search_places. Returns canonical attributes (name/coords/category/type), localized i18n names+descriptions, wiki image URLs, ratings aggregates, plus extras only this tool provides: the raw OpenStreetMap tags of the primary OSM feature, and direct links to OSM, Wikidata, and Wikipedia. Use this after nausika_search_places returns a result you want to drill into. For proximity / text search, use nausika_search_places.
`nausika_get_ratings`read-only	View ratings for a place (aggregate + your own) or list all your ratings. Inputs: place_id, my_only, limit, offset. Examples: - Place ratings: place_id="a1b2c3d4" (8-char short-id or full UUID) - My ratings: my_only=true Tip: ratings are visible in nausika_search_places results to help other sailors.
`nausika_get_routes`read-only	Look up your saved sailing-route library: direct fetch by id, or paginated search by name fragment via query, with limit and offset for pagination. Examples: - List all (defaults limit=20, offset=0): (no params) - Detail by id: id="a1b2c3d4" (8-char short-id or full UUID) - Search: query="Corsica", limit=10, offset=0 - Only itineraries: route_type="itinerary" Tip: feed leg coordinates into nausika_marine_forecast or nausika_tides to check conditions along the route.
`nausika_is_water`read-only	Check whether a coordinate (latitude, longitude in decimal degrees) is on water or land, and how far it is from the coast. Returns: - is_water: boolean (true if over sea, false if over land) - distance_to_coast_m: meters to the nearest coastline boundary; meaningful on either side (sea → distance to shore, inland → distance to sea, e.g. Rome ≈ 25 km). - source: detection source Useful to verify waypoints in route planning, or to gauge how coastal/inland a point is.
`nausika_manage_boat_profile`destructive	Manage boat profile (multi-boat per account, keyed by name). Inputs: action, name, type, loa_m, beam_m, draft_m, displacement_kg, engine_type, engine_hp, fuel_capacity_l, motor_consumption_l_per_h, water_capacity_l, cruising_speed_kts, max_speed_kts, safety_equipment, certifications. Examples: action="upsert", name="Freya", type="sail", loa_m=12.5; action="delete", name="Freya"; action="set_default", name="Freya". Tip: speed/consumption enrich nausika_sea_route ETA.
`nausika_manage_favorite`destructive	Add or remove a place from your favorites list. Examples: - Add: action="add", place_id="a1b2c3d4", note="Great anchorage for overnight" - Remove: action="remove", place_id="a1b2c3d4" place_id accepts the 8-char [xxxxxxxx] shown by nausika_search_places, or a full UUID. Find places first with nausika_search_places, then bookmark by place_id.
`nausika_manage_rating`destructive	Rate a place (1-5 stars) with an optional private comment. One rating per user per place. Examples: - Rate: action="upsert", place_id="a1b2c3d4", score=4, comment="Clean facilities" - Delete: action="delete", place_id="a1b2c3d4" place_id accepts the 8-char [xxxxxxxx] shown by nausika_search_places, or a full UUID. Find places first with nausika_search_places, then rate by place_id.
`nausika_manage_route`destructive	Save a sailing route or multi-day itinerary; legs may link to places. Typical flow: compute legs with nausika_sea_route, then save here. Examples: - Single: action="upsert", name="Genova → Bastia", route_type="single", legs=[{...}] - Itinerary: action="upsert", name="Corsica Trip", route_type="itinerary", legs=[{leg_order:1,...,pois:[{place_id:"a1b2c3d4",role:"overnight"}]}] - Delete: action="delete", id="a1b2c3d4" id and leg pois[].place_id accept either the 8-char [xxxxxxxx] short-id (from nausika_get_routes / nausika_search_places) or a full UUID.
`nausika_marine_forecast`read-only	Marine + atmospheric forecast at (latitude, longitude in decimal degrees). Returns waves, swell, currents, SST, wind, gusts, pressure, weather_code, visibility, precipitation, temperature, UV. Directions FROM. Presets: now, today, tactical (default 3d), planning (8d), extended (14d), none. Windows: start_hour/end_hour, start_date/end_date, forecast_hours, forecast_days. Extra via variables[]. Covers only a rolling window near today (~16 days ahead for atmospheric data, ~8 days for marine/wave data) — for dates further out, use nausika_seasonal_forecast (1-7 month outlook) instead. Pass include_percentiles=true to also fetch the ECMWF IFS-ENS 50-member ensemble and expose <var>_p10/_p50/_p90 series for atmospheric variables (precipitation, wind, gusts, pressure, temperature, etc.) alongside the deterministic forecast. Use it when forecast uncertainty matters — convective setups, planning/extended horizons, or any time the deterministic precip total looks inconsistent with the precipitation_probability. Waves/swell/currents/SST remain deterministic (no public ensemble). Default false to keep payload small. Example: latitude=41.39, longitude=9.16, preset="today". Chain nausika_geocode for place→coords.
`nausika_search_places`read-only	Nautical place search by proximity in the curated areas (Mediterranean, European Atlantic + Canaries, Caribbean, South-East Asia). latitude+longitude are ALWAYS required — this is not a standalone text search. 'query' is only a name filter applied within that radius; to find a place by name without known coordinates, call nausika_geocode first. Returns name, coords, distance_km, ratings, i18n names, wiki/OSM links. Each result is prefixed with an 8-char [xxxxxxxx] short-id usable as place_id in nausika_get_place / nausika_manage_favorite / nausika_manage_rating / nausika_manage_route legs[].pois[]. Inputs: latitude, longitude, radius_km, query, type, types, category, shelter_from, bottom_type, names_lang, min_coverage_score, max_coverage_score, limit, offset. Example: latitude=44.3, longitude=9.21, radius_km=50, query="marina genova", category="poi". Chain nausika_geocode → nausika_search_places → nausika_get_place(short-id).
`nausika_sea_route`read-only	Maritime routing via pgRouting Dijkstra on the MARNET sea-lane graph (detailed coastal routing in the curated areas — Mediterranean, European Atlantic + Canaries, Caribbean, South-East Asia; main ocean lanes elsewhere; errors when an endpoint is far from any lane), 6 kn sailing-yacht default, snaps land coordinates to the nearest marina/anchorage/port. Returns distance, ETA, waypoint count, GeoJSON. Examples: - Genova → Bastia: origin_lat=44.4, origin_lon=8.93, dest_lat=42.7, dest_lon=9.45 - Distance-only: same coords with include_waypoints=false Tip: chain nausika_geocode → here → nausika_calculator.
`nausika_seasonal_forecast`read-only	Fetch 1-7 month ECMWF SEAS5 seasonal forecast for one point, anywhere in the world. Returns ensemble-mean DAILY + MONTHLY aggregates of wind, SST, temperature, precipitation, cloud cover (extend via variables[]). NO waves — chain nausika_marine_forecast for short-term wind + waves. Inputs: latitude, longitude, start_date, end_date, variables. Example: latitude=40.12, longitude=9.01, start_date="2026-08-01", end_date="2026-08-31". SEAS5 forecasts forward only: a start_date in the past is clamped to today and an end_date beyond today+210d is clamped to the horizon, both reported in the response. A window that ends in the past is rejected.
`nausika_tides`read-only	Tide predictions or station discovery at a coordinate (latitude, longitude). Default: predictions from the nearest NOAA station; outside US waters falls back to a global modeled-tide source (forecast horizon ~15 days — longer windows are truncated, not rejected). Set stations_only=true to discover stations (capped by limit). Tune the window with begin_date (YYYYMMDD) + range_hours, the reference with datum, and output units (metric/english). The modeled path reports range_m (peak-to-trough). Across most of the Mediterranean this is under 0.3 m, i.e. negligible for recreational navigation — the response says so explicitly, and you should not present such values as an actionable tide window. Tides matter on the Atlantic coasts, in the Gulf of Gabès, the northern Adriatic, and in the tidal streams of the Messina and Gibraltar straits. Example: latitude=37.77, longitude=-122.42. Chain nausika_geocode for place→coordinates; pair with nausika_marine_forecast.
