Does this MCP use official JMA data?

Yes, it pulls data directly from the JSON endpoints used by the Japan Meteorological Agency.

How is the earthquake intensity measured?

It uses the official Japanese Shindo scale, which ranges from 0 to 7, providing more local detail than global magnitude scales.

Can I get weather forecasts for specific cities?

Yes, you can use the weather forecast and warning capabilities by providing the specific prefecture or sub-prefecture office codes.

What kind of disaster alerts are included?

The real-time feed includes earthquake bulletins, volcanic activity notices, and tsunami warnings.

Which AI clients can use this MCP?

You can connect this MCP to any compatible client, including Claude, Cursor, Windsurf, and VS Code.

Do I need an API key or registration?

No. This MCP reads the same JSON/XML endpoints the official jma.go.jp portal uses. fully public, no authentication.

Why is JMA better than USGS for Japan earthquakes?

JMA measures the Shindo seismic-intensity scale (0-7) at thousands of stations across Japan. two quakes with the same magnitude can have very different intensity. It also issues the official Japanese warnings, volcanic bulletins and tsunami notices. USGS reports magnitudes globally; JMA reports what people actually feel.

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Real work

What teams actually run

Travel Safety Briefings

An agent can compile a weather and earthquake safety report for a specific city before a trip.

Real-time Monitoring

A user can have their AI client watch the disaster feed for immediate tsunami or volcanic alerts.

News Aggregation

An agent can pull the latest earthquake bulletins to provide accurate local intensity reports.

Weather Planning

A user can check weekly weather trends to plan outdoor activities in different prefectures.

One connector, every AI

JMA works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put JMA to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of JMA, so you can see the experience inside your AI.

It does not authenticate your account with JMA. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.
