Which app do you use?

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": {
    "denpyo": {
      "command": "npx",
      "args": [
        "-y",
        "denpyo-mcp"
      ],
      "env": {
        "EVM_PRIVATE_KEY": "your-value",
        "SVM_PRIVATE_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add denpyo --env EVM_PRIVATE_KEY=your-value --env SVM_PRIVATE_KEY=your-value -- npx -y denpyo-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": {
    "denpyo": {
      "command": "npx",
      "args": [
        "-y",
        "denpyo-mcp"
      ],
      "env": {
        "EVM_PRIVATE_KEY": "your-value",
        "SVM_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": {
    "denpyo": {

      ],
      "env": {
        "EVM_PRIVATE_KEY": "your-value",
        "SVM_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.

Common questions

Is Denpyo MCP 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: EVM_PRIVATE_KEY, SVM_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 (0.1.1) reached the registry 4 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.

denpyo-mcp

MCP server for Denpyo — Japan Invoice & Receipt Reader API (https://denpyo-api.hp-vladic.workers.dev).

OCR Japanese invoices (請求書) and receipts (領収書) from local files or URLs into structured JSON — vendor/merchant, line items, 8%/10% consumption-tax breakdown — with the qualified-invoice registration number (インボイス登録番号, T+13 digits) extracted and verified against the National Tax Agency registry in the same call.

Pays per call via x402 (USDC on Base or Solana). The wallet is the account — no signup, no API keys.

Usage

{

"mcpServers": { "denpyo": { "command": "npx", "args": ["-y", "denpyo-mcp"], "env": { "EVM_PRIVATE_KEY": "0x... (Base wallet holding USDC)" } } } }

Solana instead: set SVM_PRIVATE_KEY (base58) rather than EVM_PRIVATE_KEY.

Example prompts once connected: *"Read C:\scans\invoice-0712.pdf and tell me if the issuer is a registered qualified-invoice issuer"* / *"Process every receipt photo in this folder and total the deductible amounts by tax rate."*

Failed analyses (unreadable files) return errors and are not charged. Documents are processed transiently and never stored.
