AI-powered terrain and procedural generation for Unreal Engine 5. One MCP server, one UE plugin.

Copy packages/hayba/Plugins/HaybaMCPToolkit/ into your UE project's Plugins/ folder:

YourProject/
  Plugins/
    HaybaMCPToolkit/   ← copy here

Right-click your .uproject file → Generate Visual Studio project files, then recompile. Enable in Edit > Plugins > Hayba MCP Toolkit.

Add to ~/.claude/claude_desktop_config.json (create it if it doesn't exist):

{
  "mcpServers": {
    "hayba-mcp": {
      "command": "npx",
      "args": ["-y", "@hayba/mcp"]
    }
  }
}

Restart Claude Desktop. You should see hayba-mcp connected in the MCP panel.

Open UE, go to Tools > Hayba MCP Toolkit, and follow the setup wizard to configure your API key and output paths.

claude mcp add hayba-mcp -- npx -y @hayba/mcp

npm install        # Install all workspaces
npm run build      # Build all packages
npm test           # Test all packages
