MCP Face Transform Server

A Model Context Protocol (MCP) server that exposes the AceDataCloud Face Transform API — face keypoint detection, beautification, age/gender transform, face swap, cartoonization, and liveness detection.

Status: All Face APIs are currently in Alpha. Interfaces may evolve.

Features

• Keypoint detection — 90+ landmarks per face, multi-face supported
• Beautification — smoothing, whitening, face slimming, eye enlarging
• Age transform — age or de-age a portrait
• Gender transform — swap perceived facial gender characteristics
• Face swap — move a source face onto a target image (with optional async webhook)
• Cartoonize — render a portrait in animated / cartoon style
• Liveness detection — distinguish live captures from printed / screen photos
