Details
From the project READMEBlank 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
| Tool | What it does |
|---|---|
list_templates | Lists the industry invoice templates available at blankinvoicemaker.com/templates (slug, name, description, URL). |
create_invoice | Builds 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": "[email protected]" },
"client": { "name": "Globex LLC", "email": "[email protected]" },
"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
Keeping templates in sync
src/templates-data.ts is generated from the Blank Invoice Maker template registry:
BIM_APP_DIR=/path/to/blank-invoice-maker npm run generate:templates

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
