Blank Invoice Maker — MCP Server

An MCP server that lets any AI assistant (Claude, and other MCP clients) create invoices with Blank Invoice Maker — the free, no-signup, no-watermark invoice generator.

Ask your assistant to make an invoice, and it returns a link that opens blankinvoicemaker.com with the invoice fully pre-filled, ready to review and download as a PDF.

Privacy by design. The invoice data travels inside the link's URL fragment (#invoice=…) and is decoded entirely in your browser. Nothing is uploaded — consistent with Blank Invoice Maker's no-account, no-server-storage model.

Tools

ToolWhat it does
list_templatesLists the industry invoice templates available at blankinvoicemaker.com/templates (slug, name, description, URL).
create_invoiceBuilds an invoice from your details and returns a pre-filled blankinvoicemaker.com link to review and download.
create_invoice example

"Invoice Globex LLC for 10 hours of design at $90/hr and one $120 hosting setup, net 14, in GBP."

The assistant calls create_invoice with:

{
  "business": { "name": "Acme Studio", "email": "hi@acme.studio" },
  "client": { "name": "Globex LLC", "email": "ap@globex.com" },
  "items": [
    { "description": "Design work", "quantity": 10, "unitPrice": 90, "unit": "hours" },
    { "description": "Hosting setup", "quantity": 1, "unitPrice": 120 }
  ],
  "currency": "GBP",
  "paymentTerms": "Net 14"
}

…and returns a https://blankinvoicemaker.com/#invoice=… link that opens the editor pre-filled.

Installation

Requires Node.js 18+.

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "blank-invoice-maker": {
      "command": "npx",
      "args": ["-y", "blank-invoice-maker-mcp"]
    }
  }
}
Other MCP clients

Run the server over stdio:

npx -y blank-invoice-maker-mcp

How it works

create_invoice maps your input into the invoice structure used by blankinvoicemaker.com, compresses it with lz-string, and appends it to the site URL as a #invoice= fragment. Opening the link hydrates the editor in your browser — no signup, no watermark, no data leaving your machine.

Development

npm install
npm run build       # compile TypeScript to dist/
npm test            # build + run the unit tests
npm start           # run the server over stdio
