Vigi-Sky is a remote MCP server that gives an AI agent 20 tools, among them aurora, capabilities, cite. It answers at https://vigi-sky.fr/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 10 September 2026; the last check, on 19 October 2026, succeeded.
Factual sky for AIs: ISS, auroras, archives. Never confuses unexplained with extraterrestrial.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
aurora | Live Kp/aurora odds from Vigi-Sky (NOAA) plus France Kp 6/7/8–9 thresholds. Inputs: lat, lon, lng, lang |
capabilities | Map of this public MCP + the shipped local vigisky-sentinel (23 typed tools, stdio/127.0.0.1). |
cite | Map a user question to the best Vigi-Sky (or GEIPAN) URL to cite. Inputs: query, lang |
doctrine | Vigi-Sky identity and method: never 'UFO detected', Hatch vs live corpus, book ISBN, founder. Inputs: lang |
first_skies | Query Ciel des peuples: 9 named nations, asterisms with RA/Dec, sources, attested vs interpretation vs reserved. nation=dine | q=pléiades | western=orion | theme=agriculture | lat=44 for horizon honesty. Never 'the Indians'. Inputs: lat, lon, lng, lang, nation, q |
hatch_search | Filter Hatch cases near a point by country/text. Approximate geocode. Inputs: lat, lng, lon, radius_km, country, q |
hatch_stats | Hatch UDB stats (decades, countries) + wiki lessons. Archive, not live 2026. |
hypothesis_rank | Rank cheap natural hypotheses from a free-text sighting. No origin claim. Inputs: description |
identify | Match a timed azimuth/elevation to known bright satellites. Verdict: compatible | no_catalog_match | insufficient_data. Never 'UFO detected'. Inputs: lat, lon, lng, lang, az, el |
iss_passes | Upcoming bright satellite/ISS passes (SGP4). night_only=true keeps only dark+sunlit passes. Inputs: lat, lon, lng, lang, limit, include_tle |
nasa_apod | NASA Astronomy Picture of the Day via Vigi-Sky. |
nearby_cases | Historical Hatch UDB cases near a point. Archive 1900–2002, approximate geocode — not live Vigi-Sky reports. Inputs: lat, lon, lng, lang, radius_km |
neo_watch | Near-Earth objects for today (astronomy, not UAP). |
nights_network | Public Sentinel night reports. Currently empty — says so honestly. |
object_lookup | Quick Messier/deep-sky hint. q is required (M31, M42, M45…). No silent default. Inputs: q |
observation_conditions | Night/moon/solar observing-conditions score. NOT a UFO-appearance probability. Inputs: lat, lon, lng, lang |
solar | Live solar/CME context plus current Kp from Vigi-Sky APIs. |
starlink_trains | Recently launched Starlink trains (count + launch id). |
status | Vigi-Sky API health, Hatch archive size, public observation counts. |
tonight_sky | Kp + next potentially visible satellite pass + First Skies asterisms. Default night_only=true (no daylight ISS). Inputs: lat, lon, lng, lang, night_only |

It answered our last check on 19 October 2026 in 152 ms. Over 6 checks since 10 September 2026 it answered 6. Status here comes from Neuronto's own probes, not from the publisher.
Yes. It is published by vigi-sky.fr and served from vigi-sky.fr, the vendor's own domain: https://vigi-sky.fr/mcp.
20, as returned by the server's own tools/list on 11 September 2026: aurora, capabilities, cite, doctrine, first_skies, hatch_search, hatch_stats, hypothesis_rank, and 12 more.
It answered our last check on 19 October 2026 in 152 ms. Over 6 checks since 10 September 2026 it answered 6.
Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://vigi-sky.fr/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: fr.vigi-sky. Endpoint host: vigi-sky.fr. ARD identifier: urn:air:fr.vigi-sky:mcp:vigisky.
First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
