Tokyo WBGT MCP Server

Heat-stress index forecasts and readings for Tokyo, from the Ministry of the Environment's data.

LABSCO SUMMARY

Only one of the seven sites has real measurements.

Six are forecast-only; measured values come from the Tokyo site at Koishikawa Botanical Garden alone. That is a property of the source network, not of this server, but it decides which tool answers your question. Forecast data refreshes hourly and measurements on the hour, so a cached answer more than an hour old is worth re-fetching.

What it is

A WBGT server for Tokyo. WBGT is the heat-stress index that combines temperature, humidity and radiant heat, and it is the number Japanese guidance actually uses to decide whether outdoor activity is safe.

What you get

  • get_tokyo_wbgt_forecast returns forecast values for one site — tokyo, hachioji, fuchu, nerima, ome, ogochi or edogawa
  • get_all_tokyo_locations fetches the forecast for every site at once
  • get_tokyo_realtime_data returns measured values for a given year and month, available for the Tokyo site only
  • Every reading arrives with its danger band attached — below 21°C is safe, 21-25°C is caution, 25-28°C is warning, 28-31°C is severe warning, and 31°C or above means exercise should stop

Requirements

The project tokyo-wbgt-mcp-server, version 1.0.0, built from source: npm install, npm run build, then point the client at build/index.js with node. Node.js 18+ and TypeScript 5+. No account and no key — the data is the Ministry of the Environment's public heatstroke-prevention feed.

Setup effort

Build from source — git clone https://github.com/yukit7s/cc-get-wbgt.git
