Take visual screenshots of web pages via Playwright MCP
intentnavigate to a URL and capture a visual PNG/JPEG screenshot (viewport or full-page) using the Playwright MCP server — for visual verification, regression testing, or content archivingconstraints
no-authcredential-freestdio transportnpx launcherheadless browser
Common agent task: visually verify a web page renders correctly, capture a screenshot for a report, or archive a page's visual state. The Playwright MCP server's browser_take_screenshot tool returns a real pixel screenshot (PNG/JPEG), unlike browser_snapshot which returns a text-based accessibility tree.
Two-step flow:
browser_navigate— open the target URL in a headless Chromium instancebrowser_take_screenshot— capture viewport or full-page screenshot, save to disk
No API key required. Runs via npx @anthropic-ai/mcp-server-playwright or npx @anthropic/mcp-server-playwright over stdio. Headless by default.

Recipe: Visual screenshots via @anthropic-ai/mcp-server-playwright
Server launch
npx @anthropic-ai/mcp-server-playwright
# stdio transport, no API key, headless Chromium by defaultMCP config (claudedesktopconfig.json / settings.json)
{
"mcpServers": {
"playwright": {
"command": "npx",
"args": ["@anthropic-ai/mcp-server-playwright"]
}
}
}Step 1: browser_navigate — open the target URL
Tool call:
{
"name": "browser_navigate",
"arguments": {
"url": "https://tani.ai"
}
}Real response (executed 2026-06-10):
- Page URL:
https://tani.ai/ - Page Title:
Tani — The first stop for AI agents - Also returns an accessibility snapshot YAML file as a side-effect
Step 2a: browsertakescreenshot — viewport screenshot
Tool call:
{
"name": "browser_take_screenshot",
"arguments": {
"type": "png",
"filename": "tani-homepage-screenshot.png"
}
}Real response (executed 2026-06-10):
- Saved viewport screenshot to
./tani-homepage-screenshot.png - Default viewport size (typically 1280×720)
- Generated Playwright code:
await page.screenshot({ path: '...', scale: 'css', type: 'png' })
Step 2b: browsertakescreenshot — full-page screenshot
Tool call:
{
"name": "browser_take_screenshot",
"arguments": {
"type": "png",
"filename": "tani-homepage-fullpage.png",
"fullPage": true
}
}Real response (executed 2026-06-10):
- Saved full scrollable page to
./tani-homepage-fullpage.png - Captures entire page height beyond the viewport fold
Key details
- Screenshot tools:
browser_take_screenshot(visual pixels) vsbrowser_snapshot(accessibility tree text). Use screenshot for visual QA, snapshot for element interaction. - Formats:
png(default, lossless) orjpeg(smaller files) - Element screenshots: pass
elementdescription +targetref to screenshot a specific element - Full page:
fullPage: truecaptures the entire scrollable page, not just the viewport - File output: screenshots save to the working directory; filename defaults to
page-{timestamp}.pngif not specified - Headless by default: no display needed, suitable for CI/server environments
- Cold start: ~5-10s on first npx invocation (Chromium download on first install), <2s thereafter
- No auth, no API key, no env vars — fully credential-free
