Implementation Reference

• src/sketchup_mcp/server.py:343-359 (handler)

  The main handler function for the 'get_selection' MCP tool. It establishes a connection to SketchUp via socket, sends a JSON-RPC 'tools/call' request to SketchUp's 'get_selection' tool with empty arguments, and returns the JSON-encoded result or an error message.

  @mcp.tool()
  def get_selection(ctx: Context) -> str:
      """Get currently selected components"""
      try:
          sketchup = get_sketchup_connection()
          result = sketchup.send_command(
              method="tools/call",
              params={
                  "name": "get_selection",
                  "arguments": {}
              },
              request_id=ctx.request_id
          )
          return json.dumps(result)
      except Exception as e:
          return f"Error getting selection: {str(e)}"
