We put the VINCAP record of listed wine companies behind an MCP server, so you can ask Claude, ChatGPT or Cursor about wine stocks and get answers with the filing each number came from. No key, no sign-in.
Ask it to rank every tracked company by net margin (latest reported period) and the top and bottom look like this:
| Rank | Company | Country | Net margin | Period |
|---|---|---|---|---|
| 1 | Laurent-Perrier | France | 16.3 % | FY to 31 Mar 2026 |
| 2 | PT Hatten Bali | Indonesia | 13.8 % | FY to 31 Dec 2025 |
| 3 | Wine's Link International | Hong Kong | 11.2 % | FY to 31 Mar 2026 |
| 4 | Delegat Group | New Zealand | 10.8 % | FY to 30 Jun 2026 |
| 5 | CITIC Niya Wine | China | 9.3 % | H1 to 30 Jun 2026 |
| … | ||||
| 41 | Treasury Wine Estates | Australia | −42.1 % | FY to 30 Jun 2026 |
| 42 | Scheid Vineyards | USA | −44.3 % | H1 to 31 Aug 2026 |
| 43 | Vifrana | Romania | −144.6 % | H1 to 30 Jun 2026 |
Treasury Wine Estates owns Penfolds. Its fiscal-2026 revenue was A$2,561 million and its net result was a loss of A$1,078.7 million; the server returns both lines with the results announcement PDF and the page they were read from.
Claude Code:

Cursor and other MCP clients (Streamable HTTP, no key):
{ "mcpServers": { "vincap": { "url": "https://vincap.co/api/mcp" } } }
Or call it raw, it is plain JSON-RPC over HTTP:

A company that has not reported the figure you weighted is listed unscored, never scored as zero. In the margin ranking above, 43 of 47 companies are scored; Lanson-BCC, Maison Pommery & Associés, Bodegas Riojanas and Thang Long Wine come back at the end with "missing": ["margin"]. A zero would quietly push them to the bottom of a list an agent then summarises as fact.
The full investor calendar with recorded outcomes and the monthly estates record are paid per call over x402 ($0.01 in USDC); everything above is free.
