SnowSure MCP Server — ski resort snow for Cursor, Claude & AI agents

Model Context Protocol server for real-time powder rankings, 14-day multi-model snow forecasts, and 500+ ski resorts via SnowSure.

Use the hosted Streamable HTTP MCP — no install required. Paste https://www.snowsure.ai/mcp into Claude.ai, ChatGPT, Cursor, or any other client that supports remote MCP. 39 tools + 12 resources, including ask_snowdata (grounded Q&A) and 4 ChatGPT Apps SDK UI widgets.

This npm package (v3.7+) is a thin stdio bridge: it proxies every request to the hosted server, so it exposes the same full tool surface. Use it only when your client cannot connect to HTTP MCP.

Installation

Recommended: hosted Streamable HTTP MCP (no install)

Most modern MCP clients (Claude.ai, ChatGPT desktop, Cursor, MCP Inspector) support the Streamable HTTP transport. Add this URL as a remote / HTTP MCP server in your client of choice:

https://www.snowsure.ai/mcp

That's it — no install, no local Node process, always tracking the latest release. The endpoint is public and stateless; reads need no auth.

Alternative: install the npm package (stdio bridge)

For clients that only support stdio MCP servers, run the bridge locally — it proxies to the hosted server with the identical tool surface.

For Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "snowsure": {
      "command": "npx",
      "args": ["-y", "snowsure-mcp-server"]
    }
  }
}

For Cursor

Add to your MCP settings:

{
  "snowsure": {
    "command": "npx",
    "args": ["-y", "snowsure-mcp-server"]
  }
}
