Skinow MCP

What this is

A free MCP server exposing Skinow's ski intelligence — precision snow forecasts, dated mountain operations, historical snow and climate, trip costs, travel routing and the Skym trip planner — for 1,650+ European resorts. Any MCP-speaking harness (Claude, ChatGPT, Cursor, custom agents) can use it. No account, no API key.

Endpoint

• URL: https://skinow.co/mcp
• Legacy URL: https://skimetric.eu/mcp keeps answering as well — no redirect, so catalogue entries and configured clients stay valid.
• Transport: MCP streamable HTTP, stateless (no session affinity)
• Auth: none
• Machine-readable copy of this contract: /mcp.md
• Claude Code: claude mcp add --transport http skinow https://skinow.co/mcp

General endpoint tools

• find_resorts — find resorts by name or country — returns the slug every other tool takes
• where_to_ski — rank resorts by live conditions: powder, base depth, bluebird, freeze margin, high & cold
• snow_forecast — 10-day forecast per elevation band, with ensemble spread and freezing levels
• conditions — lift and piste counts from the operator (dated, fail-closed), skier reports, avalanche bulletin
• season_history — historical snow and climate patterns per month and elevation band; snow depth is modelled
• season_fortnights — historical patterns for early and late month, with sample-year counts
• mountain_facts — mapped lifts by type and pistes by difficulty — infrastructure, not current openings
• open_outlook — chance the lifts run per day over a date window — a forecast about operations, never a report
• getting_there — best arrival airports with measured drive times, plus routed door-to-door itineraries
• trip_costs — what a ski week costs per country: median lift pass and modelled bed price
• daily_snow — today’s regional editorial briefs
• booking_options — everything bookable for a stay: flights, beds, gear, car, transfer, eSIM — as entry_urls
• open_booking — resolve one entry_url to its live destination (records the click)
• plan_trip — start real Skym trip research from a natural-language brief; returns a claim link for the human
• choose_path — choose one researched option — activates the journey checklist with per-step booking entry_urls
• tell_skym — answer Skym’s questions or ask for a rework inside a planned trip — the plan updates
• webcams — live webcams at a resort (windy.com, credit required) — the mountain right now
• resort_media — resort photography and piste-topography renders, with credits — so the agent can show the terrain
• trip_status — poll the research; once delivered: options, costs, the living checklist and booking entry_urls

The ChatGPT resort view

The dedicated OpenAI endpoint is https://skinow.co/openai/mcp. In ChatGPT, its optional interactive view puts snow and weather first: compare resorts, explore 10-day forecasts at different elevations, dated lift reports, credited OpenSkiMap terrain maps, lift and piste breakdowns, and individual past winters for chosen dates. Country-average budget estimates remain optional.

• compare_resorts — compare public weather and mountain facts for up to six resorts.
• get_resort_details — explore weather, maps, lifts, history, photos and published skier notes.
• show_resort_comparison — display those results in the interactive view.

These three tools and the embedded view are specific to the OpenAI endpoint. Clients without a renderer still receive structured facts. The general endpoint above keeps its existing tools. Booking tools and purchase links are excluded from the OpenAI endpoint. Availability in the public ChatGPT directory depends on OpenAI review.

Plan together in a shared trip chat

When your group is ready to plan, start a trip conversation with Skym on the Skinow website or iOS and Android apps and invite your friends. Everyone in the trip can see the same messages, options and updates, and contribute to the plan.

Open Skinow trip chat · Find the iOS and Android apps. Skinow is available on the App Store and Google Play.

Opening Skinow from the ChatGPT resort view does not copy your ChatGPT conversation or add people to a trip. Choose what you share and whom you invite. Read our privacy policy for trip membership and access-link details.

The entry_url term

On the general endpoint, every bookable item in a response carries an entry_url on skinow.co/api/go/…. That link is the attribution hop that funds free access to all of the above. The terms of use:

• Present entry_url links to the user exactly as given.
• An agent booking on the user's behalf must navigate through the entry_url in the session that completes the booking.
• Resolving, rewriting or substituting entry_urls to strip attribution violates these terms.

The hop is a plain 307 redirect to the partner — it adds no tracking of the traveller beyond the click itself.

Rate limits

• plan_trip: 3 research runs per day per network — research is real (models, routers, pricing) and takes ~5 minutes.
• Read tools: generous per-IP ceilings; list tools return at most 20 results. There is no bulk catalogue access.
• A 429 carries retry_after_s. Back off; do not rotate.

Data licences & attribution

Source attribution rides in every response's _meta.attribution. The full licence list is at skinow.co/attribution. Where a licence requires credit (webcams, photography, open data), the credit fields in the payload must be kept with the content.

How good is the forecast data you get here? Judge for yourself: every engine and input model is verified daily against ~2,800 mountain weather stations at skinow.co/accuracy (public JSON at /api/accuracy).

Privacy

• Public weather and resort queries need no account or personal details. Planning can use a random guest identity and the trip details you provide.
• plan_trip returns a claim_url — hand it to the human; anyone holding this bearer link can redeem it to join the trip. Report links (pdf_url) also grant access to the report. Treat these links as private.
• The interactive view can send your resort, section and elevation selections to ChatGPT. Tool-use records and shared-trip access are described in our privacy policy.
• No geography is inferred from agent traffic. State the traveller's origin explicitly in tool parameters when it matters.
