Aseprite

SpriteWare runs an MCP server that lets an agent open a sprite, draw pixels, read
the result back and export a PNG. It drives Aseprite for the agent: the window
you have open, or a hidden Aseprite when none is.

The mascot's idle animation The mascot's smile animation The mascot's blush animation The mascot's loading animation

I built the mascot sprite animations by hand. The other sprite assets in the app are AI, just to show what the MCP can do.

Download

Latest release.

Platform File
Windows Windows installer SpriteWare-windows-amd64-installer.exe
Windows Windows portable SpriteWare-windows-amd64.exe
macOS macOS (Apple Silicon and Intel) SpriteWare-macos-universal.dmg
Linux Linux binary SpriteWare-linux-amd64
Debian Linux package SpriteWare-linux-amd64.deb

The builds are unsigned. Windows: SmartScreen → More info → Run anyway.
macOS: right-click the app click Open. Linux binary: chmod +x it first. For Mac, you may need to allow apps from unidentified developers in System Preferences then Security & Privacy.

Run it

Aseprite 1.3+ is required. First launch asks for its executable.
The Server screen starts the MCP server and writes the entry into your assistant's
config (Claude Desktop and Claude Code, VS Code, Zed, Cursor, Windsurf, Cline,
Gemini CLI, Codex, OpenCode, Kiro). I have not tested them all to check if the intalls work correctly but if there are any issues, please make an issue on GitHub.

Getting Aseprite

No compiler needed: buy it on aseprite.org, Steam or Humble Bundle. A free trial is on aseprite.org.

Its source is free to build yourself if you would rather not buy it (i did buy it, lol. Just follow the intructions or get LibreSprite). Follow INSTALL.md:

Build

npm --prefix frontend run build
go build -o bin\spriteware.exe .

task build runs both. Go 1.26+ and Node 24.

Docs

dev-docs covers the architecture, the Aseprite protocol,
tests, and releasing.
