Invovate MCP Server

Let AI agents generate PDF, JSON, and UBL 2.1 invoices in 11 languages(including right-to-left Arabic, Japanese, Hindi, and Cyrillic) through theInvovate 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.	Recommended
`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

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 Globexfor 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 theWindsurf MCP settings).

Run from source (before npm publish)

git clone <this repo> && cd 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.
