Getting Started

Just ask your AI agent (e.g. Claude Code) to create a Pyxel game. The agent will automatically discover and set up pyxel-mcp from the MCP Registry.

Manual Installation

1. Install the package:

pip install pyxel-mcp

2. Register pyxel-mcp as an MCP server in your AI agent. For Claude Code, add to your project's .mcp.json:

{
  "mcpServers": {
    "pyxel": {
      "type": "stdio",
      "command": "pyxel-mcp"
    }
  }
}

MCP Registry
