## 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[].

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. 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". 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. 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 (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. 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. 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.

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.

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. Endpoint: https://mcp.nausika.app
- nausika_get_boat_profile (Get Boat Profile) - 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. Endpoint: https://mcp.nausika.app
- nausika_manage_favorite (Manage Favorite) - 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. Endpoint: https://mcp.nausika.app
