Scoping to the observation endpoint keeps every answer grounded in a real reading rather than a model, which is the right trade for "is it raining right now".

A Node MCP server over the Korea Meteorological Administration's short-term forecast service, answering questions about conditions at the current hour.
- Current conditions for a named Korean city, drawn from the KMA's live short-term observation data
- Plain questions work — asking about Seoul, Gwacheon, Incheon or Daejeon right now returns an answer
