Texel

For developers

Let your AI agent make Minecraft skins.

A Texel skin is a JSON file with a palette and a list of drawing steps. Your agent writes it, renders it, reads the review and fixes whatever it flags.

Open the studio Connect your agent
frost-mage.skin.json agent

brief

Format

Skins as JSON

Selectors target faces of the player model: head.front, legs.sides@overlay. Faces use local coordinates, so “the bottom two rows of every leg” is one line. Pixel art is just strings.

  • 13 operations fill, rect, pixels, gradient, noise, shade, mirror and more.
  • Deterministic The same spec produces the same PNG in the browser, the CLI and the MCP server.
  • Never throws Invalid layers are skipped and reported with a JSON path and a fix hint.

Families

Many skins from one file

A family is a base spec plus patches. Axes multiply: three guilds × two ranks is six consistent skins. Guilds recolor palette roles; ranks toggle layers by id.

Pick a member to see the patches that build it.

MCP, CLI or browser

A single self-contained file: nine tools (render, validate, save, families, import, diff), three prompts, and an interactive 3D viewer in MCP Apps hosts. Works offline; writes stay inside a workspace directory.
