v0.6.0

First public release.

An MCP server that lets an AI assistant draw in Aseprite — live, in the real
editor, on your canvas. Two pieces talk over a local WebSocket: a Python MCP
server and a Lua extension inside Aseprite.

Install

Server — nothing to install ahead of time:

claude mcp add aseprite -- uvx aseprite-mcp

Plugin — download aseprite-mcp.aseprite-extension below and double-click
it, or add it from Edit → Preferences → Extensions → Add Extension. Then
restart Aseprite — extensions load only at startup.

Requires Aseprite 1.3 or newer. Either end can start first; the plugin retries
until the server is there and reconnects on its own afterwards.
