Free no-signup invoice MCP server for Claude & Cursor — generate PDF, JSON, and UBL 2.1 invoices in 11 languages via the Invovate invoice API.

Invovate MCP Server

Invovate MCP Server is a free, no-signup invoice MCP server for Claude, Cursor, and other MCP clients — it generates invoices as PDF, JSON, and UBL 2.1 via the Invovate invoice API.

Let AI agents generate PDF, JSON, and UBL 2.1 invoices in 11 languages (including right-to-left Arabic, Japanese, Hindi, and Cyrillic) through the Invovate invoice API. Works with Claude Desktop, Cursor, Windsurf, and any MCP-capable client.

JSON math works with no API key; PDF/UBL output uses a free key.

Tools

| Tool | What it does | Key needed | |------|--------------|------------| | calculate_invoice_totals | Compute subtotal, discounts, tax, shipping, deposit, grand total, balance due — no file rendered. | No | | generate_invoice_pdf | Generate a PDF. Returns a 7-day hosted link (great for chat), or writes the file when save_path is given. | Required | | generate_invoice_ubl | Generate UBL 2.1 XML (interoperability/archival only — not regulated e-invoicing). | Yes | | get_invoice_capabilities | List supported languages, templates, currencies, and features. | No |

Get a free API key

Sign up at https://invovate.com/auth — your key starts with inv_. Free tier, no credit card. (calculate_invoice_totals works without a key; PDF, UBL, QR, and hosted links require a free key.)

Install

Claude Desktop

Add to claude_desktop_config.json (~/Library/Application Support/Claude/claude_desktop_config.json on macOS, %APPDATA%\Claude\claude_desktop_config.json on Windows):

{
  "mcpServers": {
    "invovate": {
      "command": "npx",
      "args": ["-y", "invovate-mcp-server"],
      "env": { "INVOVATE_API_KEY": "inv_your_key_here" }
    }
  }
}

Restart Claude Desktop. Then ask: “Create an invoice for Acme BV billing Globex for 3 consulting days at €900/day with 21% VAT, in English, and give me the PDF.”

Cursor / Windsurf

Add the same block to the MCP config (~/.cursor/mcp.json for Cursor, or the Windsurf MCP settings).

Run from source (before npm publish)

git clone https://github.com/LightSpeedPlusOne/invovate-mcp-server.git
cd invovate-mcp-server && npm install
INVOVATE_API_KEY=inv_your_key node src/index.js

…and point your client at it:

{
  "mcpServers": {
    "invovate": {
      "command": "node",
      "args": ["/absolute/path/to/mcp-server/src/index.js"],
      "env": { "INVOVATE_API_KEY": "inv_your_key_here" }
    }
  }
}

Configuration

| Env var | Default | Purpose | |---------|---------|---------| | INVOVATE_API_KEY | — | Free API key (inv_…). Enables PDF/UBL output and hosted links. | | INVOVATE_API_BASE | https://invovate.com | Override the API base (rarely needed). |

Test

npm test                                   # lists tools + JSON math (no key)
INVOVATE_API_KEY=inv_xxx npm test          # also exercises the PDF hosted-link path

Notes

Not regulated e-invoicing. UBL export is for interoperability/archival only. No Peppol / Factur-X / ZUGFeRD / XRechnung / NF-e compliance or network delivery.
Hosted links expire and the invoice is deleted after 7 days.
