## Tools
- nausika_marine_forecast (Marine + Atmospheric Forecast) - 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[].

Example: latitude=41.39, longitude=9.16, preset="today". Chain nausika_geocode for place→coords. Endpoint: https://mcp.nausika.app
- nausika_seasonal_forecast (Seasonal Forecast) - Fetch 1-7 month ECMWF SEAS5 seasonal forecast for one Mediterranean point. 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". Limits: end_date ≤ today+210d, range ≤ 215d. Endpoint: https://mcp.nausika.app
- nausika_tides (Tides) - 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. 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).

Example: latitude=37.77, longitude=-122.42. Chain nausika_geocode for place→coordinates; pair with nausika_marine_forecast. Endpoint: https://mcp.nausika.app
- nausika_search_places (Search Places) - Mediterranean nautical place search by proximity. 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). Endpoint: https://mcp.nausika.app
- nausika_get_place (Get Place) - 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. Endpoint: https://mcp.nausika.app
- nausika_sea_route (Sea Route & Distance) - Maritime routing via pgRouting Dijkstra on the MARNET sea-lane graph (Mediterranean only; errors out elsewhere), 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. Endpoint: https://mcp.nausika.app
- nausika_calculator (Calculator) - 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). Endpoint: https://mcp.nausika.app
- nausika_geocode (Geocode Place Names) - 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. Returns name, type, coords, plus similarity (forward) or distance_m (reverse).

Example forward: query="Portofino". Example reverse: latitude=44.3, longitude=9.21, radius_m=50000.

Chain into nausika_marine_forecast, nausika_tides, nausika_search_places, or nausika_sea_route using the returned coords. Endpoint: https://mcp.nausika.app
- nausika_describe_place_schema (Describe Place Schema) - 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. Endpoint: https://mcp.nausika.app
- nausika_is_water (Is Water) - 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. Endpoint: https://mcp.nausika.app
- nausika_convert_coordinates (Convert Coordinates) - 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. Endpoint: https://mcp.nausika.app
- nausika_manage_boat_profile (Manage Boat Profile) - 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.
