Screenshot API for MCP clients. Capture any URL as PNG with mockup mode support.
Connect Nightglass to Claude, Cursor or any other MCP client and it stops being a tab you switch to. Screenshot API for MCP clients. Capture any URL as PNG with mockup mode support. The nightglass mcp server is what makes that connection.
Take website screenshots from any MCP-compatible client — Claude Desktop, Cursor, Windsurf, Claude Code, and more.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
take_screenshot — Capture a screenshot of any website. Returns a PNG image directly in the conversationcheck_balance — Check your account balance and remaining screenshot creditsConfiguration is passed through the environment: NIGHTGLASS_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
The server ships on npm as nightglass-mcp, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Plenty of browser automation servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Nightglass's toolset — take_screenshot, check_balance — is a fair guide to whether it matches your workflow. It is maintained by mizukaizen; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
