Pixel MCP is an MCP server by Willibrandon, designed to expose Aseprite's pixel art and animation capabilities programmatically. Built using Go 1.23+, this free tool connects AI assistants and coding agents to Aseprite, enabling natural language control over pixel art creation. It acts as a bridge, translating requests into Aseprite commands. Users can deploy it through the Claude Code plugin marketplace or by integrating the pixel-plugin repository. This allows developers to automate and generate pixel art directly from AI prompts, enhancing creative workflows.

What does Pixel MCP connect to?

Pixel MCP functions as an MCP server, primarily connecting to Aseprite, a popular pixel art and animation editor. Its core purpose is to programmatically expose Aseprite's functionalities to AI assistants, enabling automated pixel art creation. The server translates requests from AI clients into actions within Aseprite, effectively making the editor's capabilities accessible via code. This direct integration allows external programs to manipulate canvases, layers, and drawing tools within Aseprite without manual intervention.

Core features and tools

Pixel MCP provides over 40 callable tools, all prefixed with "mcp__aseprite__*". These include fundamental Canvas & Layer Management and Drawing Primitives for creating basic shapes like pixels, lines, and circles. It also offers Selection Tools for manipulating areas, alongside Animation tools for sequence control. Advanced capabilities cover Reference Analysis, Color Quantization, Automatic Shading, Dithering, Palette Management, and Antialiasing. Additionally, Transform Operations and Export & Import Tools are available for managing and outputting pixel art.

Who is it for?

Pixel MCP targets AI assistants, coding agents, and developers aiming to programmatically generate and modify pixel art using natural language. It is ideal for integrating pixel art creation into automated workflows or AI-driven design processes. It allows for the generation of game assets or animated sprites through textual commands. This tool empowers those seeking to automate visual content creation within the pixel art domain. Skip this if you prefer manual, direct interaction with Aseprite without needing AI or programmatic control.

How to get started

No credentials are required. The core workflow involves configuring the absolute path to the Aseprite executable.

Use cases

• Creating pixel art sprites using natural language commands, such as "Create a 64x64 Game Boy style sprite" or "Draw a red circle with blue outline."
• Animating pixel art, for example, by adding a 4-frame walk cycle or setting frame timings.
• Exporting game-ready pixel art in formats like PNG, GIF, or spritesheets with JSON metadata for game engines such as Unity, Godot, and Phaser.

Pixel MCP offers a powerful bridge for AI assistants and developers to interact with Aseprite programmatically. It simplifies the creation and manipulation of pixel art through over 40 exposed tools, ranging from basic drawing to advanced animation and export. Its ability to automate complex pixel art tasks using natural language makes it a valuable asset for content generation. Try animating pixel art by adding a 4-frame walk cycle to a sprite.
