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.
| 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 |
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.)
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.”
Add the same block to the MCP config (~/.cursor/mcp.json for Cursor, or the
Windsurf MCP settings).
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" }
}
}
}| 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). |
npm test # lists tools + JSON math (no key)
