Do I need an API key?

No. This reads NOAA's public Space Weather Prediction Center feeds, which require no key or account.

What is an X-class flare?

The classes A, B, C, M and X each mark a range of X-ray flux, and each letter is ten times the previous one. X is the strongest: a major flare that can trigger planet-wide radio blackouts. M-class is moderate; C-class is minor and common.

How fresh is the data?

The X-ray and magnetometer feeds publish a new sample every minute. Results are cached for one minute per call.

Solar Flares MCP Connector for Claude

A+

Live solar X-ray flux, detected solar flares and GOES magnetometer conditions from NOAA SWPC — the A/B/C/M/X class of the Sun right now, keyless.

More Details Connect to Claude

Connect any AI agent to live solar activity — the measurements NOAA's GOES satellites beam down every minute, published by the Space Weather Prediction Center. No key required.

What you can do

Ask what the Sun is doing right now — the current X-ray class (A, B, C, M or X), the peak over the last hour and whether the flux is climbing
List detected solar flares — begin time, peak class and end time for each event SWPC has identified, with a minimum-class filter so you see only M and X events when they matter
Pull the X-ray flux curve — from the last 10 minutes up to seven days, already converted to NOAA classes, sampled to stay small
Check the geomagnetic field at the satellite — the Hp component, its one-hour swing and a quiet/active/storm label, an early warning that a storm is arriving
Get a one-look briefing — current class, biggest recent flare and geomagnetic state in a single answer

Why it matters

X-class flares can trigger planet-wide radio blackouts; M-class flares disrupt high-frequency radio at the poles. Satellite operators, airlines, grid managers and aurora hunters all watch the same feed.

5 tools expose this connector's capabilities to your AI agent.

get_solar_flare_status

1–0.8 nm channel, its NOAA class (e.g. "C3.4") and whether the flux is rising or falling. X-class means a major flare; M-class is moderate. Readings flagged for electron contamination are provisional. For the full curve use list_xray_flux_history; for detected events use list_solar_flares. Get the current solar X-ray class right now — A, B, C, M or X — from the NOAA GOES satellite, plus the peak and the trend over the last hour. This is the "is the Sun active?" headline tool

list_xray_flux_history

Up to 360 minutes reads the 6-hour feed at full one-minute cadence; longer requests read the 7-day feed and sample it down to at most 120 points so the response stays small. Points are oldest-first so the curve reads left to right. Each point carries its NOAA class already computed, so no flux math is needed downstream. Get the recent solar X-ray flux curve as class-tagged samples — the input to any "how is solar activity evolving" or "when did that flare peak" question

get_geomagnetic_conditions

The level label is derived from the one-hour Hp swing: storm >= 40 nT, active >= 20, unsettled >= 8, otherwise quiet. Readings with the arcjet flag set are contaminated by a station-keeping burn. For aurora probability, pair this with a planetary K-index source. Get the live GOES magnetometer reading — the Hp component, its swing over the last hour, and a quiet/active/storm label. Use this for "is a geomagnetic storm arriving"

get_space_weather_summary

Follow up with list_solar_flares for event detail or list_xray_flux_history for the curve. If the geomagnetic part is absent the magnetometer feed was momentarily unavailable, not silently dropped. One-look space weather briefing: current X-ray class, the biggest recent flare, and the geomagnetic state — the right first call for any solar-storm question

list_solar_flares

An event with no end time is still in progress, and an event whose peak is pending shows no class yet — SWPC writes "Unk" for its max_time. Use min_class "M" or "X" when the question is about flares that matter for Earth; C-class events are common and mostly harmless. When nothing clears the minimum, the unfiltered list is returned with a note rather than an error. List solar flare events detected by NOAA SWPC — begin time, peak class and end time for each, newest first. Pass min_class to see only significant flares
