Implementation Reference

• src/sketchup_mcp/server.py:256-290 (handler)

  The handler function for the 'create_component' MCP tool. It connects to Sketchup via socket, sends a JSON-RPC 'tools/call' request with the tool name and arguments, and returns the result as JSON string. The function signature defines the input schema (type, position, dimensions). The @mcp.tool() decorator handles registration.

  @mcp.tool()
  def create_component(
      ctx: Context,
      type: str = "cube",
      position: List[float] = None,
      dimensions: List[float] = None
  ) -> str:
      """Create a new component in Sketchup"""
      try:
          logger.info(f"create_component called with type={type}, position={position}, dimensions={dimensions}, request_id={ctx.request_id}")
          
          sketchup = get_sketchup_connection()

              }
          }
          
          logger.info(f"Calling send_command with method='tools/call', params={params}, request_id={ctx.request_id}")
          
          result = sketchup.send_command(
