Marine, maritime, nautical and sailing data for AI assistants and chatbots. Mediterranean marine forecast: wind, wave, swell, gust. Tide tables and tidal predictions. Sea routing and passage planning on a coastline-aware maritime graph. Curated POIs: marinas, ports, harbors, anchorages, moorings, fuel. Real data, cited sources, never invented.
nausika is a remote MCP server published at mcp.nausika.app. It has been probed 6 times since 9/10/2026. It answered in 6 of them (100.0%), a near-uninterrupted record. Median response time is 448 ms, placing it among the faster endpoints. It exposes a broad tool surface of 19 tools. On the protocol side it still runs 2025-11-25 and has not moved to the newer spec.

Each block is one measurement round. Green: working response. Amber: responded but the server was returning errors (5xx). Red: no response at all.
Each cell is one probe run. Faded cells are incomplete probes — one leg did not answer, so the era is inconclusive.
The two probe legs separately: modern server/discover and legacy initialize.
