MCP server for the Avalanche.org Public API map-layer endpoints
MCP server for the Avalanche.org Public API map-layer endpoints
Add this to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):
The server publishes 4 tools. What each one is for:
avalanche_danger_rating_by_point — Get the current avalanche danger rating for a lat/lon point. Returns the zone the point falls in, or the nearest zone if preferNearest is truehistoric_avalanche_danger_rating_by_point — Same as above, but for a specific historic date. Returns all the same fields plus dayraw_map_layer — Returns the raw Avalanche.org map-layer GeoJSON FeatureCollection for all avalanche centersraw_map_layer_by_avalanche_center — Returns the raw map-layer GeoJSON FeatureCollection for a single avalanche centerThe server ships on npm as @modelcontextprotocol/inspector, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Avalanche Org's toolset — avalanche_danger_rating_by_point, historic_avalanche_danger_rating_by_point, raw_map_layer and 1 more — is a fair guide to whether it matches your workflow. It is maintained by haydenwade; worth a glance at recent repository activity before you build anything load-bearing on it.

Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.
