EM Snow missed one check this week
Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
snow
add_snow_report
Only relay a report from a person who is at, or was just at, the resort. Never invent a report. The report goes live immediately and is labelled as relayed via an AI assistant.
get_snow_reports
Get recent visible community reports, including whether each came from the website or was relayed by an AI assistant.
snow_reliability
Get an explainable snow-reliability score from long-run ERA5 snow depth.
avalanche
avalanche_danger
Summarise the regional avalanche bulletin covering a resort: EAWS in Europe, avalanche.org centres in the US and Avalanche Canada, with zone, issuing centre, issue and expiry times and a link to the official forecast. Expired products are never shown as current. Never substitutes for the official bulletin or local advice.
best
best_time_to_go
Get historical snow odds from the local ERA5 archive and quiet-week guidance where the crowd scorer covers the resort.
conditions
get_conditions
Get current snow, reported lift and run counts, weather and season state. Lift and run counts are reported status, not guaranteed live.
extended
get_extended_outlook
Get a 16-day daily outlook (snowfall, temperatures, freezing level, maximum gusts and, for the first days, precipitation probability) from EM Snow's self-hosted GFS and ECMWF IFS models. Days 1 to 7 overlap get_forecast; days 8 to 16 are low-confidence trend guidance only.
fly
fly_this_mountain
Get a link that plays a simulated 3D tour of a resort in the EM Snow flyby (lifts up, named runs down, on the mapped piste network), or a tour of runs you name. Pick names match like route_on_mountain; ambiguous names return candidates with picker ids. Status is ready, limited (small mapped network, the tour may be short) or unavailable (too few named runs or no linking lifts; the resort page is returned instead).
forecast
get_forecast
Get the available daily snow, temperature, freezing level and wind-hold risk forecast, up to 10 requested days.
mountain
mountain_facts
Read mapped OSM terrain inventory, lift fleet, vertical, longest run, carefully matched Wikidata facts, season dates and modelled snow reliability.
nearby
nearby_resorts
Find nearby resorts from the local EM Snow resort index.
plan
plan_my_day
Build modelled suggested runs in time order from forecast weather, sun, snow and mapped terrain. Only plans days inside the reported winter season; summer lift or bike-park operation does not count as open for skiing. Easy, intermediate and advanced exclude expert, freeride and extreme terrain; only expert permits it. Suggestions are not a connected route or live piste status.
resort
get_resort_media
Get images for a resort that vision-capable assistants can show: nearby webcams with provider credit, a Wikimedia Commons photo with its per-file licence, author and source page, the EM Snow sun and shade teaser where one exists, and the resort page link. No trail-map image is available.
resorts
search_resorts
Find ski resorts worldwide by name, country or distance. Returns at most 20 matches and does not expose the bulk resort index.
route
route_on_mountain
Route between named pistes, lifts, the resort base or latitude,longitude coordinates using mapped OSM pistes and lifts. Names match accent-insensitively and partially (exact, then prefix, then contained words); a piste or lift split into several connected OSM pieces counts as one. A lift used as from resolves to its top station, where you ski away; a lift used as to resolves to its bottom station, unless coordinates say otherwise. Ambiguous names return candidates. Coordinates more than 5 km from the resort are rejected. Easy, intermediate and advanced avoid terrain above that level; only expert permits expert, freeride and extreme terrain.
season
season_recap
Summarise the most recent completed ski season from the local ERA5 archive first.
suggest
suggest_resort
Suggest a missing resort for human review. This never adds it directly to the resort index.
sun
sun_on_the_mountain
Show modelled sun and shade windows for eight slope aspects, with local terrain-horizon shading where DEM coverage exists.
watch
watch_resort
Return a one-tap EM Snow URL where the person can watch a resort and optionally add dates. This tool does not collect email.
webcams
get_webcams
Get nearby webcam images and their source links, with the required provider credit.
where
where_is_it_snowing
Rank the freshest recently reported snow from the cached EM Snow home-page ranking.

EM Snow — questions
Answers built from our own checks of this server.
What can EM Snow do?
It exposes 21 tools, read directly from the server on our last check. Among them: add_snow_report, avalanche_danger, best_time_to_go, fly_this_mountain, get_conditions, get_extended_outlook and 15 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
Is EM Snow working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 243 ms. The bar chart above shows every period we have measured.
How do I connect EM Snow?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does EM Snow need an API key?
No. EM Snow completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 21 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is EM Snow?
It answers our handshake in 243 ms on average, which is faster than 59% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
