Nausika is an MCP server with 19 tools an agent can call, among them nausika_calculator, nausika_convert_coordinates, nausika_describe_place_schema. It answers at https://mcp.nausika.app over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 4 September 2026; the last check, on 17 October 2026, succeeded.
Mediterranean marine, nautical, sailing: forecasts, tides, sea routes, anchorages, POIs for AI.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
nausika_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() Inputs: expression, precision |
nausika_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). Example Inputs: latitude, longitude |
nausika_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. Inputs: type |
nausika_geocode | 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 ('loca Inputs: query, latitude, longitude, radius_m, limit |
nausika_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. Inputs: name |
nausika_get_favorites | 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. Inputs: limit, offset |
nausika_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, w Inputs: id |
nausika_get_ratings | 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 vi Inputs: place_id, my_only, limit, offset |
nausika_get_routes | 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 Inputs: id, query, route_type, limit, offset |
nausika_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 coas Inputs: latitude, longitude |
nausika_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_ Inputs: action, name, type, loa_m, beam_m, draft_m |
nausika_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_ Inputs: action, place_id, note |
nausika_manage_rating | 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 ac Inputs: action, place_id, score, comment |
nausika_manage_route | 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=[{...}] - Itiner Inputs: action, id, name, description, route_type, legs |
nausika_marine_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 Inputs: latitude, longitude, preset, forecast_days, forecast_hours, start_date |
nausika_sea_route | 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, Inputs: origin_lat, origin_lon, dest_lat, dest_lon, speed_knots, units |
nausika_search_places | 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, ca Inputs: latitude, longitude, radius_km, query, type, types |
nausika_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_fore Inputs: latitude, longitude, start_date, end_date, variables, include_members |
nausika_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 tr Inputs: latitude, longitude, stations_only, limit, begin_date, range_hours |

It answered our last check on 17 October 2026 in 193 ms. Over 10 checks since 4 September 2026 it answered 10. Status here comes from Neuronto's own probes, not from the publisher.
Yes. It is published by nausika.app and served from mcp.nausika.app, the vendor's own domain: https://mcp.nausika.app.
19, as returned by the server's own tools/list on 9 September 2026: nausika_calculator, nausika_convert_coordinates, nausika_describe_place_schema, nausika_geocode, nausika_get_boat_profile, nausika_get_favorites, nausika_get_place, nausika_get_ratings, and 11 more.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.nausika.app. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 31 August 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
