Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Paint MCP Paint a sunset over the mountains using the oil paint mode."
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
A drawing canvas exposed as an MCP server. An LLM connects over stdio and paints on a pygame window using tool calls.
pip install -r requirements.txtRelated MCP server: aseprite-mcp
python server.pyThis opens an 800x600 pygame canvas and starts the MCP server on stdio. Connect any MCP-compatible client (e.g. Claude Desktop) to the process.

When oil paint mode is enabled:
Color mixing — the brush picks up existing canvas color as it moves, so overlapping strokes blend naturally.
Paint depletion — strokes start opaque and gradually thin out as the brush runs dry. Each new stroke reloads the brush.
Soft edges — dabs use concentric rings with cubic falloff for painterly texture.
Brush shapes — five brush types (round, flat, filbert, fan, palette_knife) create distinct stroke characteristics. Flat for broad washes, filbert for general work, fan for blending, palette knife for bold impasto.
Shapes disabled — rectangles, ellipses, and flood fill are blocked. Only points, lines, and paths are available.
batch_strokes is the recommended way to paint — send many short strokes per call, each with its own color, brush size, and brush shape.

server.py — Entry point. Runs the pygame main loop and drains commands from a thread-safe queue.
tools.py — MCP tool definitions. Pushes drawing commands onto the queue.
canvas.py — Drawing engine. Wraps a pygame surface with draw ops, oil paint simulation, and an undo stack.
