## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-28.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 66/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 1395 tokens (~66/item across 21 items; 21 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 67/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 21 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 22 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-09-28 (score 70, +1)

- [functional] We updated how we score, so this day's move reflects our rubric, not a change to the server

### 2026-09-27 (score 69)

First indexed and scored.

## MCP tools (21)

### `search_resorts` (~63 tokens)

Search resorts

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

Input parameters:

- `country` (string)
- `limit` (integer)
- `near` (object)
- `query` (string)

### `get_conditions` (~42 tokens)

Get conditions

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

Input parameters:

- `resort` (string, required)

### `get_forecast` (~47 tokens)

Get forecast

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

Input parameters:

- `days` (integer)
- `resort` (string, required)

### `plan_my_day` (~103 tokens)

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.

Input parameters:

- `date` (string)
- `level` (string)
- `resort` (string, required)

### `sun_on_the_mountain` (~48 tokens)

Sun on the mountain

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

Input parameters:

- `date` (string)
- `resort` (string, required)

### `route_on_mountain` (~175 tokens)

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.

Input parameters:

- `avoid_closed` (boolean)
- `from` (string, required)
- `level` (string)
- `resort` (string, required)
- `to` (string, required)

### `avalanche_danger` (~79 tokens)

Avalanche danger

Expired products are never shown as current. Never substitutes for the official bulletin or local advice.

Input parameters:

- `resort` (string, required)

### `mountain_facts` (~45 tokens)

Mountain facts

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

Input parameters:

- `resort` (string, required)

### `where_is_it_snowing` (~41 tokens)

Where is it snowing

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

Season recap

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

Input parameters:

- `resort` (string, required)

### `snow_reliability` (~34 tokens)

Snow reliability

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

Input parameters:

- `limit` (integer)
- `resort` (string, required)

### `watch_resort` (~43 tokens)

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.

Input parameters:

- `resort` (string, required)

### `add_snow_report` (~86 tokens)

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.

Input parameters:

- `observed_today` (boolean)
- `rating` (integer)
- `resort` (string, required)
- `tags` (array)
- `text` (string, required)

### `suggest_resort` (~69 tokens)

Suggest resort

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

Input parameters:

- `country` (string, required)
- `lat` (number, required)
- `lon` (number, required)
- `name` (string, required)
- `notes` (string)
- `website` (string)

### `get_extended_outlook` (~93 tokens)

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.

Input parameters:

- `days` (integer)
- `resort` (string, required)

### `get_resort_media` (~75 tokens)

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.

Input parameters:

- `resort` (string, required)

### `fly_this_mountain` (~133 tokens)

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).

Input parameters:

- `level` (string)
- `pick` (array)
- `resort` (string, required)
- `runs` (integer)

## Common questions

### What is the EM Snow MCP server?

EM Snow is an MCP server listed in the public MCP registry as uk.co.extreme-media.snow/em-snow. Ski resort conditions, forecasts, avalanche danger, sun, routes and snow history for 5,000+ resorts. This page covers its hosted endpoint (https://snow.extreme-media.co.uk/mcp).

### Is the EM Snow MCP server safe to use?

EM Snow scores 70 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the EM Snow MCP server expose?

EM Snow exposes 21 tools: search_resorts, get_conditions, get_forecast, plan_my_day, sun_on_the_mountain, and 16 more. Their descriptions and schemas cost roughly 1,359 tokens of context every time the server is loaded.

### Does the EM Snow MCP server require authentication?

No. We connected to EM Snow without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the EM Snow MCP server still maintained?

EM Snow is still listed as active in the MCP registry. We last reached this channel on 28 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
