Overview

AI-generated overview

Lets an assistant look up Japan weather forecasts and official disaster alerts, including warnings and earthquake information.

What you can do
This remote MCP server exposes Japan Meteorological Agency data to an assistant. Based on its description, it covers weather forecasts, disaster warnings, and earthquake information for Japan. It is a hosted endpoint, so the assistant connects to it directly rather than running anything locally.
When to use it
Useful when you need current or forecast Japanese weather, official warnings, or earthquake details while working in an assistant. Suited to travel planning, local safety checks, or any task that depends on JMA conditions in Japan.
Requirements
A remote MCP client that supports streamable HTTP, plus network access to the provider's endpoint. No authentication, API keys, environment variables, or headers are declared, and no local runtime or package is needed.
Before you install
The server is operated by a third party and relays official JMA data; treat outputs as informational and confirm critical safety decisions against official sources. No credentials are requested, and no write, send, or delete actions are described.

Installation

In SourceWeft

  1. Open Japan Weather & Alerts in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.fujimura-ui%2Fjapan-weather-alerts-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.
