This tutorial covers how to add the Rendex MCP Server as a goose extension to capture screenshots, generate PDFs, and render HTML to images from any webpage or raw HTML — useful for archiving UIs, generating invoices and reports, producing OG images, and giving goose a reliable "see the web" capability without spinning up a full browser automation stack.
Configuration
:::tip Quick Install

Add a Remote Extension (Streaming HTTP) extension type with:
Endpoint URL
https://mcp.rendex.dev/mcp
Custom Request Header

Example Usage
Let's use the Rendex extension to generate an invoice PDF from raw HTML and archive a product page.
goose Prompt
1. Render this HTML as an A4 PDF with 1cm margins:
<!doctype html>
<html>
<body style="font-family: system-ui; padding: 40px;">
<h1>Invoice #0042</h1>
<p>Bill to: Acme Corp</p>
<table>
<tr><td>MCP server listing</td><td>$500.00</td></tr>
<tr><td>Total</td><td><b>$500.00</b></td></tr>
</table>
</body>
</html>
2. Then take a full-page screenshot of https://news.ycombinator.com in dark mode
3. Return both results so I can save them
goose Output
I'll generate the invoice PDF first, then capture the HN page.
[rendex_screenshot: format=pdf, pdfFormat=A4, pdfMargin={top: 1cm, ...}, html=<invoice markup>]
✓ PDF captured successfully (12,344 bytes)
width: 1280 height: 800 capturedAt: 2026-04-15T12:34:56Z
[rendex_screenshot: url=https://news.ycombinator.com, fullPage=true, darkMode=true]
✓ Screenshot captured (PNG, 847KB)
width: 1280 height: 4,321 waitStrategy: networkidle2
Both renders completed. You have:
1. Invoice PDF (A4, 12.3KB) — base64 in result 1
2. Dark-mode full-page screenshot of Hacker News (PNG, 847KB) — base64 in result 2
