Keen
Upscale product screenshots, marketing art, or UI assets to 2x or 4x from the agent without leaving the editor.
Overview
Keen is a Build-phase MCP server that upscales images to 2x or 4x resolution through the Keen API with agent-driven stdio tools.
What is this MCP server?
- Upscale images to 2x or 4x resolution via Keen API tools
- stdio MCP package @keenimg/mcp (npm registry v1.0.2)
- Requires KEEN_API_KEY from keenimg.com
- x402 payment model for per-use API access
- GitHub source: TelcharFromNogrod/keen-mcp
- Supports 2x and 4x upscale factors per server description
- npm package @keenimg/mcp at server schema version 1.0.2
What problem does it solve?
Low-res source images block polished marketing and UI work when you do not want to manually batch upscale in another app.
Who is it for?
Indie builders generating or refining visual assets inside Claude Code or Cursor with a Keen API key already on hand.
Skip if: Teams that need local-only processing, custom model training, or upscaling without a paid third-party API.
What do I get? / Deliverables
Your agent can request 2x or 4x upscales during implementation so deliverable graphics meet resolution needs faster.
- 2x or 4x upscaled image outputs via agent tool calls
- Repeatable upscale workflow inside the coding session

Journey fit
Asset polish and third-party media APIs sit in Build when you wire tools into the product or content pipeline. Keen is an external image API bridged over stdio MCP, which matches integrations rather than raw frontend code.
How it compares
Hosted image API over MCP, not an on-device skill or general photo editor.
