printscale-mcp

An MCP server that lets AI agents (Claude Desktop, Cursor, Claude Code, etc.) upscale images to print-ready files (TIFF + PNG + JPG) via PrintScale.

Setup

1. Create an API key at https://printscale.app/dashboard/api.

2. Add the server to your MCP client config, with the key as an env var.

Claude Desktop / Cursor (mcp config)

{
  "mcpServers": {
    "printscale": {
      "command": "npx",
      "args": ["-y", "printscale-mcp"],
      "env": { "PRINTSCALE_API_KEY": "psk_live_xxxxxxxx" }
    }
  }
}

Claude Code (CLI)

claude mcp add printscale -e PRINTSCALE_API_KEY=psk_live_xxx -- npx -y printscale-mcp

Running locally from source instead of npm? Use "command": "node", "args": ["/path/to/printscale-mcp/index.mjs"].

Tools

• printscale_upscale — upscale an image. Provide a public image_url or a local file_path. Choose mode (auto / 2x / 3x / print); for print, set cm and dpi. Returns TIFF/PNG/JPG download URLs. Charges credits.

• printscale_job — check a job's status by id.

• printscale_credits — show the remaining credit balance.

Example prompts

• "Upscale ./product.jpg to 60 cm at 300 DPI for print."

• "Upscale https://example.com/photo.png at 3x and give me the TIFF."

• "How many PrintScale credits do I have left?"

Notes

• Start from a sharp source — PrintScale enlarges detail, it doesn't repair blurry or low-quality images.

• Outputs are available for 3 days, then deleted. Download within the window.

• Credits are shared with your PrintScale account (buy them in the app).

Env: PRINTSCALE_API_KEY (required), PRINTSCALE_BASE_URL (optional, defaults to https://printscale.app).
