Spaceweather MCP vs Hindsight
A side-by-side look at the Spaceweather MCP and Hindsight MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Spaceweather MCP for aerospace & astrodynamics work as a local process; choose Hindsight for knowledge & memory as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Spaceweather MCP when
- You need dedicated capabilities in the Aerospace & Astrodynamics domain.
- You prefer a local stdio subprocess transport.
- You want tools like
get_conditions_now, get_kp_index, get_kp_forecast.
Choose Hindsight when
- You need dedicated capabilities in the Knowledge & Memory domain.
- You prefer a local stdio subprocess transport.
- Its auth model fits you: API key required.
- You have the keys it needs:
HINDSIGHT_API_LLM_API_KEY, HINDSIGHT_API_LLM_PROVIDER, HINDSIGHT_DB_PASSWORD.

get_conditions_nowSingle-call snapshot of current space weather. Returns the latest planetary Kp, interplanetary Bz/Bt, solar wind speed and density, the current NOAA G/S/R scale levels, whether a geomagnetic storm is in progress (Kp >= 5), and a human-readable one-line summary. Best first call for "what's space weather doing right now / will I see aurora" questions.get_kp_indexObserved planetary K-index time series (3-hour cadence, ~last week). Kp ranges 0-9; Kp >= 5 indicates a geomagnetic storm (G1+). Use for trend and history; for the single current value use `get_conditions_now`.get_kp_forecastNOAA's 3-day planetary Kp forecast (3-hour resolution). Each point is tagged observed/estimated/predicted. Useful for aurora-watch planning and anticipating geomagnetic disturbance.get_solar_windReal-time solar wind from DSCOVR/ACE at L1: magnetic field + plasma. Returns `mag` (Bx/By/Bz/Bt in nT, GSM) and `plasma` (density cm^-3, speed km/s, temperature K) series for the chosen window. Sustained southward Bz (negative) plus elevated speed is the classic geomagnetic-storm driver.get_alertsMost recent NOAA SWPC alerts, watches, and warnings (newest first). Plain-text bulletins for events like geomagnetic storm watches, radio blackouts, and solar radiation storms.get_noaa_scalesNOAA G (geomagnetic), S (solar radiation), R (radio blackout) scales. Returns today (index 0) plus the next 3 forecast days, each with a 0-5 scale level and label. The headline 'how bad is it' summary used by SWPC.get_27day_outlookSWPC 27-day outlook: daily F10.7 cm radio flux, planetary Ap, largest Kp. A 4-week look-ahead driven by the ~27-day solar rotation. Coarser than the 3-day Kp forecast but useful for longer-range planning.list_observatoriesThe USGS-operated magnetic observatories you can query with get_observatory. Returns 3-letter IAGA codes (BOU, HON, GUA, …) with names and coordinates, so an agent can pick a station near a region of interest.get_observatoryGround magnetometer time series for one USGS observatory (nT). `station` is an IAGA code from `list_observatories` (e.g. 'BOU'). Returns the requested field components (default X,Y,Z,F) over the last `hours`, plus the latest finite value per element. Use 60s sampling for trends, 1s for detail (heavier). Data is U.S. public domain (credit USGS); near-real-time values are preliminary.get_dstHourly Dst (disturbance storm-time) index over the last `days`, in nT. Dst tracks the ring-current depression of a geomagnetic storm: roughly > -30 quiet, -50..-100 moderate, < -100 intense, < -250 great storm. NON-COMMERCIAL data from the WDC for Geomagnetism, Kyoto. Cite "WDC for Geomagnetism, Kyoto" and the Dst DOI; real-time/quicklook values are provisional and not licensed for commercial use. Kept separate from the public-domain NOAA/USGS feeds for this reason.get_solar_flaresRecent GOES X-ray solar flares (events with peak class C/M/X), last `days`. Discrete flare events with begin/peak/end times and peak class (e.g. 'M2.1'). Best for "biggest recent flare?" / current flare activity.get_radiation_stormCurrent solar radiation (energetic proton) environment and NOAA S-scale. Latest GOES integral proton flux per energy threshold (pfu) plus the S (radiation storm) scale 0-5 derived from the >=10 MeV flux. Relevant to satellite operations, polar flights, and astronaut radiation exposure.- +3 more on the listing page

Frequently asked questions
Spaceweather MCP is categorized under Aerospace & Astrodynamics and uses a local stdio subprocess. Hindsight belongs to Knowledge & Memory and uses a local stdio subprocess. Pick Spaceweather MCP for aerospace & astrodynamics work and Hindsight for knowledge & memory.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Spaceweather MCP has no declared pricing — check the project's own site. Hindsight is listed as free. Auth: api key required. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add spaceweather-mcp and vectorize-io-hindsight as separate keys in the same mcpServers object, and your assistant will call tools from either one.
On AllMCPs, Spaceweather MCP has a quality signal of 53/100 (Good) with 2 views, 0 installs and 0 GitHub stars. Hindsight has 57/100 (Good) with 14 views, 0 installs and 53,323 GitHub stars.
