Image Upscale MCP - AI Super Resolution 2x/4x

AI-powered image upscaling with optional face enhancement. Uses Real-ESRGAN (Real Enhanced Super-Resolution GAN) for high-quality 2x or 4x super resolution.

What It Does

This MCP (Model Context Protocol) actor provides two tools for intelligent image upscaling:

Tool 1: upscale_image

Upscale any image by 2x or 4x without additional processing.

• Input: Image URL + scale factor (2 or 4)

• Pricing: $0.08 per image

Tool 2: enhance_face

Upscale images with face enhancement (better quality for portraits, profile pictures).

• Input: Image URL + scale factor (2 or 4)
• Output: Base64 upscaled image + metadata
• Pricing: $0.10 per image
