Overview

AI-generated overview

Remote MCP endpoint giving assistants English-language Japan weather warnings, typhoon, volcano and municipality code data.

What it does
This remote MCP server exposes Japan-focused public information in English, covering Japan Meteorological Agency warnings, typhoon information, volcano alert levels, and municipality code history. It is reached over streamable HTTP at a hosted endpoint, so no local package or runtime is needed. The registry description also mentions x402 checks, which suggests some form of payment-related verification, but no tool list is published.
When to use it
Worth adding when an assistant needs current Japanese weather warnings, typhoon or volcano status, or municipality code lookups and the user wants the results in English rather than Japanese. It is less useful for general weather worldwide or for non-Japanese administrative data.
Requirements
A remote streamable HTTP connection to the provider's hosted endpoint; no local runtime, package, environment variables or headers are declared. No authentication is declared. Network access to the endpoint is required.
Before you install
The description mentions x402 checks, which may involve payment or paid access; confirm any cost or payment flow before relying on it. No authentication is declared, so do not send credentials or private data to the endpoint. Tool behavior is not documented in the manifest, so verify what each call does before using it in automated workflows.
