What This Skill Does
Provides access to a global ocean tides model via a JSON-RPC API. Supports querying tide height at a specific coordinate and time, retrieving high/low extrema over a time window, and fetching meteorological grid data. Works anonymously at free-tier rate limits or with a bearer token for higher usage.
Eliminates the need to run local harmonic tide prediction libraries by exposing a global model through a single HTTP endpoint.
When to use it
- Checking tide height before launching a kayak or small boat
- Finding low-tide windows for coastal foraging or beach access
- Scheduling marina departures around predicted high tide
- Building a tide alert app for a specific harbor or cove
- Pulling wind and temperature data alongside tides for trip planning
Example Workflow
Here's how your AI assistant might use this skill in practice.
User asks: When are the high and low tides at 40.71N, 74.01W on February 10, 2026?
- 1Send a tools/call POST request to the API with method tides_extrema and the given coordinates
- 2Set start_time to 2026-02-10T00:00:00Z and end_time to 2026-02-11T00:00:00Z
- 3Parse result.structuredContent from the response
- 4Extract each extremum's time and height value
- 5Format the results as a list of high and low tide events with UTC timestamps
High tide at 06:18 UTC (1.3m), low tide at 12:44 UTC (0.1m), high tide at 18:52 UTC (1.2m)
