Pixelbolt
Create, inspect, and animate pixel art assets from editable JSON recipes using CLI commands, an MCP server, or a local studio interface.
Pixelbolt is a zero-dependency pixel art and animation toolkit designed for AI agents and game developers. It compiles human- and agent-editable JSON recipes into transparent PNGs, sprite sheets, texture atlases, animated PNGs, and GIFs with exact, repeatable pixel precision. Featuring built-in CPU fluid dynamics for fire, water, and smoke, wave effect synthesizers, and bone-and-joint character pose pipelines, it allows agents like Claude, Codex, or Cursor to draft, inspect, and fix artwork frame by frame without relying on external generative image models or complex graphics libraries.
Key Features
01Compiles JSON-based pixel recipes directly into PNG sprite sheets, texture atlases, APNGs, and GIFs
02Simulates deterministic, CPU-based fluid dynamics for seamless elemental loops like fire, smoke, water, and slime
03Provides skeletal limb and body posing templates for walk, run, jump, and combat animations
04Features zero runtime dependencies with full support via CLI, MCP server, and browser studio preview
05Enables precise AI agent inspection and pixel-level edits through dedicated MCP toolsets
