wetter-mcp-server
MCP-Server für Wetterprognosen über Open-Meteo — kein API-Key nötig.
Tools
get_current_weather(location?)— aktuelles Wetterget_hourly_forecast(location?, hours=24)— stündlich (1–48 h)get_daily_forecast(location?, days=7)— täglich (1–16 Tage)
Ohne location gilt der Standard-Ort (Steinenbronn). location kann ein
beliebiger Ortsname sein (z.B. "Bozen", "Stockholm") und wird per Geocoding
aufgelöst. Temperaturen in °C, Niederschlag in mm, Wind in km/h, Zeiten in Ortszeit.

Standard-Ort ändern
Optional über Umgebungsvariablen DEFAULT_LAT, DEFAULT_LON, DEFAULT_ORT
— z.B. bei der Registrierung mit claude mcp add … -e DEFAULT_LAT=…. Die
.env-Datei wird nicht automatisch geladen; .env.example listet nur die
Variablennamen. Ohne diese Variablen nutzt der Server Steinenbronn (Ortsmitte,
in server.py hinterlegt) — der Server läuft also ohne jede Konfiguration.

Naming Consistency5/5
All tools follow the same get_*_forecast pattern (with get_current_weather as the one slight variation, but still consistent verb_noun structure). Naming is clear and predictable.
Tool Count5/5
Three tools is an appropriate scope for a weather server, covering current, daily, and hourly data without unnecessary overlap.
