• src/servicenow_mcp/tools/script_include_tools.py:262-331 (handler)

  The handler function that executes the tool logic: sends a POST request to ServiceNow's sys_script_include table API with the provided parameters to create a new script include.

  def create_script_include(
      config: ServerConfig,
      auth_manager: AuthManager,
      params: CreateScriptIncludeParams,
  ) -> ScriptIncludeResponse:
      """Create a new script include in ServiceNow.
      
      Args:
          config: The server configuration.
          auth_manager: The authentication manager.
          params: The parameters for the request.
          
      Returns:
          A response indicating the result of the operation.

• src/servicenow_mcp/utils/tool_utils.py:685-691 (registration)
