What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs on your computer
Transport: stdio
Category: Other
You need to fill in: X402_PRIVATE_KEY

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
You fill in yourself: X402_PRIVATE_KEY

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

npmNode.js installed (for the npx command)

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "ja-normalize": {
      "command": "npx",
      "args": [
        "-y",
        "ja-normalize-mcp"
      ],
      "env": {
        "X402_PRIVATE_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add ja-normalize --env X402_PRIVATE_KEY=your-value -- npx -y ja-normalize-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "ja-normalize": {
      "command": "npx",
      "args": [
        "-y",
        "ja-normalize-mcp"
      ],
      "env": {
        "X402_PRIVATE_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "ja-normalize": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",

      ],
      "env": {
        "X402_PRIVATE_KEY": "your-value"
      }
    }
  }

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

Common questions

Is Ja Normalize safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: X402_PRIVATE_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.2) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

動かす

cp .env.example .env      # PAY_TO_ADDRESS を自分のウォレットに

npm install npm run dev # http://localhost:4021 npm run doctor # 発見用ドキュメントと402応答の自己診断 npm run check # 型チェック + テスト

未払いで叩くと 402 と PAYMENT-REQUIRED ヘッダ（base64 JSON）が返る:

curl -i -X POST localhost:4021/v1/text/normalize \

-H 'Content-Type: application/json' \ -d '{"text":"令和５年４月１日ＴＥＬ０３－１２３４－５６７８"}'

支払いを含むE2E（テストネット・買い手用の別ウォレットが必要）:

# Base Sepolia の USDC を https://faucet.circle.com で受け取っておく

BUYER_PRIVATE_KEY=0x... npm run probe -- http://localhost:4021 /v1/text/normalize

本番に出す手順

ウォレット: 受取専用のEVMアドレスを新規作成し PAY_TO_ADDRESS に設定（秘密鍵はサーバーに置かない。受け取るだけなので不要）
Coinbase CDP: https://portal.cdp.coinbase.com でAPIキーを発行 → CDP_API_KEY_ID / CDP_API_KEY_SECRET、X402_NETWORK=base （facilitator手数料: 1,000件まで無料、以降 $0.001/件。ガス代はfacilitator負担）
法人番号API: https://www.houjin-bangou.nta.go.jp/webapi/ でアプリケーションIDを申請 → HOJIN_APP_ID 発行まで2〜4週間。届くまで /v1/company/resolve は 503 を返す
デプロイ: 恒久的なドメインが必須（x402scanはngrok等のトンネルを拒否）。Render / Fly.io / Railway の無料〜最小プランで十分。PUBLIC_BASE_URL を実URLに
自己診断: npm run doctor -- https://your-domain
登録（発見されるため）

x402scan: POST https://www.x402scan.com/api/x402/registry/register-origin {"origin":"https://your-domain"} または UI から

世界の祝日は date-holidays（コードISC、データCC-BY-3.0、出典明記）
銀行・支店データは zengin-code（MIT、公開情報から自動収集）。npm update zengin-code で追従

次にやること

PAY_TO_ADDRESS を本物のウォレットに
法人番号 Web-API のアプリケーションID申請（リードタイムが一番長いので最初に）
Render/Fly にデプロイ、doctor 通す
x402scan / Circle / x402Relay に登録
死活監視（落ちたら通知）— 登録済みルートの79%が死んでいる市場なので、生きているだけで上位
インボイス登録番号の有効性検証（国税庁適格請求書発行事業者公表システム Web-API、別途ID申請）
