Unmeasured means there is not enough evidence to decide. How these checks work

Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 341 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name em-snow.

  • Pass
    Lists tools

    tools/list returned 21 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 341 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 341 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Fail
    Parameters documented

    18 of 50 parameters have a description (36%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-09-27T09:37:19.850929Z, within 180 days.

Capabilities

Tools 21

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.

Discovered
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.

Discovered
best_time_to_go

Get historical snow odds from the local ERA5 archive and quiet-week guidance where the crowd scorer covers the resort.

Discovered
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).

Discovered
get_conditions

Get current snow, reported lift and run counts, weather and season state. Lift and run counts are reported status, not guaranteed live.

Discovered
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.

Discovered
get_forecast

Get the available daily snow, temperature, freezing level and wind-hold risk forecast, up to 10 requested days.

Discovered
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.

Discovered
get_snow_reports

Get recent visible community reports, including whether each came from the website or was relayed by an AI assistant.

Discovered
get_webcams

Get nearby webcam images and their source links, with the required provider credit.

Discovered
mountain_facts

Read mapped OSM terrain inventory, lift fleet, vertical, longest run, carefully matched Wikidata facts, season dates and modelled snow reliability.

Discovered
nearby_resorts

Find nearby resorts from the local EM Snow resort index.

Discovered
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.

Discovered
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.

Discovered
search_resorts

Find ski resorts worldwide by name, country or distance. Returns at most 20 matches and does not expose the bulk resort index.

Discovered
season_recap

Summarise the most recent completed ski season from the local ERA5 archive first.

Discovered
snow_reliability

Get an explainable snow-reliability score from long-run ERA5 snow depth.

Discovered
suggest_resort

Suggest a missing resort for human review. This never adds it directly to the resort index.

Discovered
sun_on_the_mountain

Show modelled sun and shade windows for eight slope aspects, with local terrain-horizon shading where DEM coverage exists.

Discovered
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.

Discovered
where_is_it_snowing

Rank the freshest recently reported snow from the cached EM Snow home-page ranking.
