Stormglass Io for AI agents
Stormglass.io is a weather and ocean-data API providing forecasts and historical readings for wind, waves, tides, and solar conditions at any coordinate. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.
