Sunshine Atlas MCP server

A remote, read-only Model Context Protocol server that answers "where is it sunny?" with data: monthly 0–100 Sunshine Scores, day/night temperatures, rainfall and sea temperature for 3,833 destinations — every one with its own airport — from long-term climate normals. It serves the same open dataset published at sunshineatlas.com/data (CC BY 4.0, DOI 10.5281/zenodo.21322408).

Self-host

The server is a single stateless Node file (fresh McpServer per request, plain JSON responses, binds to 127.0.0.1 — put it behind your reverse proxy). It reads one dataset file and hot-reloads it on mtime change.

npm install
curl -O https://sunshineatlas.com/data/sunshine-atlas-destinations.json
PORT=8787 DATA_FILE=./sunshine-atlas-destinations.json node server.mjs

GET /healthz reports status and destination count. server.json is the MCP-registry manifest.
