This tutorial covers how to add the [Rendex MCP Server](https://github.com/copperline-labs/rendex-mcp) 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
[Launch the installer](goose://extension?type=streamable_http&url=https%3A%2F%2Fmcp.rendex.dev%2Fmcp&id=rendex&name=Rendex&description=Capture%20screenshots%2C%20generate%20PDFs%2C%20and%20render%20HTML%20to%20images%20via%20AI%20agents&header=Authorization%3DBearer%20YOUR_RENDEX_API_KEY)
Add a `Remote Extension (Streaming HTTP)` extension type with:
**Endpoint URL**
```
https://mcp.rendex.dev/mcp
```
**Custom Request Header**
```
Authorization: Bearer
```
:::
Obtain your Rendex API key and paste it in as the Bearer token. Free tier includes 500 calls/month, no credit card required.

## 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:
Invoice #0042
Bill to: Acme Corp
| MCP server listing | $500.00 |
| Total | $500.00 |
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=]
✓ 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
```
## Pricing
Rendex is free to try — no credit card required for the free tier.
