Stormglass Io

@stormglass-io what's the current wave height and wind speed at 37.7749°N, 122.4194°W?

Based on the latest marine weather data for San Francisco Bay, current conditions show significant wave height at 1.2 meters with a period of 8 seconds, wind speed at 12 knots from the northwest, and air temperature at 14°C. Water temperature is 13°C. This data reflects the most recent forecast model run; conditions update hourly.

Demonstrates the MCP's core weather-fetch capability for a single coordinate. Requires an API key with weather-data scope. Note that Stormglass aggregates multiple forecast sources, so response times can vary by region and parameter complexity. Free-tier accounts have daily request limits.

@stormglass-io find all tide stations within 50km of Vancouver and show me today's high tide times

Found 4 tide stations near Vancouver: Point Atkinson (49.33°N, 123.27°W), Vancouver Harbour (49.29°N, 123.11°W), Steveston (49.12°N, 123.18°W), and Tsawwassen (49.00°N, 123.13°W). For today, high tides occur at Point Atkinson at 06:42 (4.8m) and 19:15 (4.6m). This example shows the two-step workflow: first listing stations, then querying tide data for the nearest match.

Showcases the list-stations tool paired with tide queries. The MCP returns station metadata but doesn't auto-filter by radius—the AI handles distance logic. Tide predictions require a separate API call per station, so batching multiple locations can consume quota quickly. Useful for marine planning or coastal logistics.

@stormglass-io get solar irradiance data for 40.7128°N, 74.0060°W over the next 3 days and summarize peak generation windows for a rooftop solar array

Solar data for New York City shows peak direct normal irradiance (DNI) averaging 850 W/m² between 11:00-14:00 local time across the forecast period. Cloud cover reduces output on day 2 (60% coverage), dropping midday DNI to ~400 W/m². Optimal generation windows: Day 1 (11:30-13:45), Day 3 (10:45-14:15). Sunrise/sunset times shift ~2 minutes earlier each day. This synthesis combines hourly irradiance forecasts with sun-position angles to identify high-yield periods.

Illustrates the solar-data tool combined with AI reasoning to extract actionable insights. The MCP returns raw irradiance and sun-angle arrays; the AI interprets trends. Requires start/end timestamps in ISO 8601 format. Historical data access depends on subscription tier—free accounts get 7-day forecasts only.

When Stormglass wins for solar site surveys at scale

A 6-person solar installation company runs site surveys across three states and needs to pre-qualify roof angles and sun exposure before sending crews. Stormglass is the right call here: the solar data tool pulls irradiation and sun-position for any coordinate, and the elevation tool confirms topography that might shade panels. The team runs batch queries in Switchy during Monday planning, flags high-yield sites, and routes crews accordingly. The API key auth means no OAuth dance, so the ops lead can share one workspace credential. This breaks down if you need real-time weather during install day—Stormglass refreshes hourly, not minute-by-minute. But for pre-survey qualification, it's faster than manual Google Earth tracing and cheaper than sending scouts to every address.

Why this MCP fits small freight brokers with coastal routes

A 3-person freight brokerage coordinates container pickups at four East Coast ports and needs tide windows and weather forecasts to avoid demurrage fees. Stormglass handles this: the tide station list tool catalogs all NOAA points, the weather tool pulls marine forecasts (wave height, wind speed) for each port coordinate, and the team checks conditions in Switchy before confirming pickup times with truckers. Four tools cover the workflow without needing separate NOAA and weather APIs. The constraint is granularity—if your routes hit inland depots more than ports, you're paying for marine data you won't use. But for coastal logistics under 50 shipments a week, this is the simplest stack to avoid weather-related delays and coordinate with port schedules.

When Stormglass is overkill for event planners

A 4-person event production team books outdoor weddings and corporate retreats and wants to assess weather risk 48 hours before setup. Stormglass can do this—the weather tool pulls forecasts for any venue coordinate—but it's borderline. The MCP shines if you're also checking elevation for drainage issues or solar data for tent placement in summer heat. If you only need basic precipitation and temperature, a simpler weather API or even a shared Weather.com bookmark is faster. The API key setup is easy, but you're paying for marine and solar parameters you'll ignore. Use Stormglass if your events span beaches, mountains, or open fields where topography and sun angle matter. For urban venues with standard tents, skip it and save the subscription cost.
