The pixel-art studio agents can see — headless, over MCP.

Rust · MCP · Pixel Art · CLI

A headless pixel-art studio that AI agents drive over MCP. Every drawing op is a tool call, and doc_look hands back a PNG the agent can actually look at, judge, and correct — the same look-and-fix loop a human uses in an editor. One static Rust binary — no API keys, no network, fully deterministic.

Engineering notes

The look-and-fix loop

Agents are good at describing art and bad at seeing it. Every op is a tool call and `doc_look` returns a PNG the agent judges and corrects — closing the loop a human gets for free in an editor.

An eye, not just a hand

Critique, palette, silhouette, animation and colour-blindness audits turn “does it look right?” into numbers an agent acts on — and `doc_set_audit` judges a whole asset set as one game.

Game-ready output

Spritesheets with pivots, hitboxes and tags; animated GIFs and APNGs; packed texture atlases; Tiled-ready tilesets and engine-standard JSON. Any engine can slice it.
