Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

Tool list from our last check. Connect live to refresh it.

get_geomagnetic_now Read-only

Answers "is there a magnetic storm now / today?", "what is the Kp index?", "how is space weather?". The current planetary K index (Kp) and NOAA G-scale storm level, when it was observed and whether it is still current, the next storm in the NOAA 3-day forecast, and a one-sentence summary. Data from NOAA SWPC and GFZ Potsdam. Geophysical data only; no health information.

timeZonestring

IANA time zone of the person asking, such as Europe/Moscow or America/New_York. Local times and days use it. Defaults to UTC.

get_geomagnetic_now

read-only

Argument	Type	Description

    }
  }
}

get_kp_forecast_3day

Answers "will there be a magnetic storm tomorrow?", "geomagnetic forecast for the next days", "when does the storm start?". NOAA's 3-day planetary K index forecast laid over today, tomorrow and the day after in the asker's time zone: each day's peak, every three-hour interval (measured once it has begun, forecast after), the next storm and a one-sentence summary. Geophysical data only; no health information.

read-only

Argument	Type	Description
timeZone	string	IANA time zone of the person asking, such as Europe/Moscow or America/New_York. Local times and days use it. Defaults to UTC.

    }
  }
}

get_kp_history

Answers "were there magnetic storms yesterday / this week / this month?", "what was the strongest storm lately?". What the planetary K index did over the last 24 hours (hourly peaks of the NOAA estimate), 7 days (three-hourly values) or 30 days (daily peaks), in the asker's time zone, with the maximum and how many values reached a storm. Gaps are null, not zero. Geophysical data only; no health information.

read-only

Argument	Type	Description
period	string	24h: hourly peaks; 7d: three-hourly values; 30d: daily peaks. Defaults to 24h. The service keeps 30 days.
timeZone	string	IANA time zone of the person asking, such as Europe/Moscow or America/New_York. Local times and days use it. Defaults to UTC.

    }
  }
}

get_moon_phase

Answers "what is the moon phase today?", "when is the next full moon / new moon?". The Moon on a day in the asker's calendar: what the day is called (new moon, waxing crescent, first quarter and so on), how much of the disc is lit, its age, the next full and new moon, and the four main phases of that month, in local time. Computed with Meeus and checked against US Naval Observatory tables; useful for planning aurora watching.

read-only

Argument	Type	Description
date	string	A calendar date, YYYY-MM-DD, in the given time zone. Defaults to today there.
timeZone	string	IANA time zone of the person asking, such as Europe/Moscow or America/New_York. Local times and days use it. Defaults to UTC.

Answers "magnetic storms next week / this month", "any storms expected on a given date?". NOAA's 27-day outlook: for each day the largest expected Kp and its storm level, the expected Ap index and 10.7 cm radio flux. Days are UTC calendar dates, as NOAA issues them. Reissued weekly; a coarse outlook, not a day-by-day forecast. Geophysical data only; no health information.

Answers "were there solar flares today?", "was there an X-class flare?", "is the Sun active?". The GOES X-ray level now (and whether it is current), the strongest X-ray flux of the last 24, 72 or 168 hours with its NOAA radio blackout level, and the solar flares NOAA recorded in that time: class, begin, peak and end, and whether one is in progress. Times in the asker's time zone. Data from NOAA SWPC.
