MCP-Weather

MCP-Weather is an MCP server that retrieves regional Japanese meteorological forecasts by connecting to a Japan Meteorological Agency compatible weather API. Built for developers, AI agent creators, and users working in IDEs like Cursor, it enables AI assistants to query detailed Japanese weather overviews, precipitation chances, and wind metrics. The server supports major cities across Japan, including Tokyo, Osaka, Sapporo, and Fukuoka. Users can run the tool locally without authentication for simplified desktop setups, or deploy it as a remote server on Cloudflare Workers secured with OAuth 2.0 and token management. Through its dedicated tools, MCP-Weather supplies three-day outlooks, four-period daily precipitation percentages, and localized wind speed details. This setup allows coding assistants and automated workflows to answer natural language questions about Japanese weather conditions accurately without requiring manual web searches or external dashboard visits.

Part of MCP Servers

What is MCP-Weather?

MCP-Weather is a Model Context Protocol server that supplies real-time weather forecasts and meteorological observations across major Japanese cities using a Japan Meteorological Agency compatible data API.

What tools are available in MCP-Weather?

The server exposes three primary tools: get_weather_overview for general forecasts and multi-day summaries, get_precipitation_probability for six-hour time block rain forecasts, and get_wind_speed for localized wind direction and intensity.

Does MCP-Weather require authentication?

Running the server locally does not require any authentication. If deployed remotely to Cloudflare Workers, access is secured using OAuth 2.0 with token generation utilities.

Which Japanese cities are supported by MCP-Weather?

It supports dozens of major prefectural capitals and cities across Japan, including Tokyo, Osaka, Kyoto, Sapporo, Sendai, Hiroshima, Nagoya, Fukuoka, and Naha.
