Let your AI assistant make the paperwork

ChatGPT, Claude, Gemini, Perplexity, Cursor or your own agent can make invoices, quotes, proforma invoices, receipts and credit notes with LuckPanda, free and without an account. It fills in the document and hands you a link that opens it here, or the PDF. You check it; you decide what is sent.

Copy a prompt

Paste this into your AI assistant

Works with ChatGPT, Claude, Gemini or Perplexity. Every tool page has its own prompt too, under the editor.

Use https://luckpanda.app/agents.md to create the business document I need with LuckPanda (an invoice, quote, proforma invoice, receipt or credit note). Ask me which one and for every detail it needs, then give me the link that opens it filled in, or the PDF.

For agents

Three ways to create a document

All free, no sign-in. Ask the person for every detail: never invent business names, tax numbers or prices.

1. Prefill link

Open any document page with the document as base64url JSON in ?doc=, or with simple parameters. The editor opens filled in and marked as coming from a link.

https://luckpanda.app/tools/invoice-generator?seller_name=Acme&buyer_name=Globex&item=Design|1|1200|20

Long document, or personal details you would rather keep out of the address bar: POST /api/public/drafts returns a short link /d/…, open for 7 days.

2. Branded PDF

Send the document to the PDF API and get the PDF back, with a small LuckPanda footer and a verification code. About 40 an hour per network.

curl -X POST https://luckpanda.app/api/public/pdf \
  -H 'content-type: application/json' \
  -d '{"doc": {…}}' -o invoice.pdf

3. MCP server

Streamable HTTP, no authentication. Tools: list_tools, get_document_rules, create_document_link, create_document_pdf, calculate_gst, calculate_vat, calculate_emi, check_gstin, find_hsn_code.

https://luckpanda.app/mcp/public

Connect the MCP server

It only makes new documents from what the agent sends; it never sees any business's data. For your own business's data, use the account server at /mcp with an agent key from your workspace.

  -H 'content-type: application/json' \
  -d '{"page":"credit-note","doc":{"country_code":"IN","seller":{"name":"…","tax_id":"…"},"buyer":{"name":"…"},"original_invoice_number":"INV-0042","original_invoice_date":"2026-10-01","reason":"product_return","lines":[{"description":"…","quantity":"1","unit_price":"1200","tax_percent":18}]}}'

Document pages

Each page is a free editor. Add .md to its address for its own agent instructions: fields, country rules, an example and a ready link. 70 more trade and country templates are listed in /agents.md.
