Nightglass

mizukaizen/nightglass-mcp

Connects Claude to the nightglass screenshot API so you can capture website renders without leaving your conversation. Exposes take_screenshot with options for full page capture, viewport sizing, mockup frames, and dark mode emulation. Returns PNGs (or JPEG/WebP) directly in chat. Also includes check_balance to monitor your API credits. Requires a nightglass API key from their dashboard, where you get 50 free screenshots to start. Useful when you need visual confirmation of how a site looks, want to grab design references, or need to verify responsive layouts without opening a browser. Works across Claude Desktop, Cursor, Windsurf, and Claude Code.
